eclipse - Disable selection change in JFace TreeViewer -

i have treeviewer in view. whenever press button (say s), viewer selects first item in tree starting letter (say stackoverflow). there way disable behaviour?

thank you.

restricting key events on tree looks promising loose navigating tree construction , expand/collapse on tree node , other functionality.

tree.addkeylistener(new keyadapter() {       @override       public void keypressed(keyevent e) {          e.doit = false;       }     });

jquery - How can i read an object filelist array in javascript? -

i have created array store list of selected files. well, have honest, looked code , when realized worked purpose, used it. need access array in order delete files manually, have tried using index of each sector, not work.

this how create array , store files.

 var files = [];  $("button:first").on("click", function(e) {                 $("<input>").prop({                     "type": "file",                     "multiple": true                 }).on("change", function(e) {                     files.push(this.files);                 }).trigger("click");  });

how read array files[] if contains object filelist or obtain indexs array?

here's how understand code:

each time first button in dom clicked file input dialogue accepts multiple files generated. upon homecoming dialogue emits change event files variable (a filelist object) attached function context (this). code pushes newly created filelist onto files array. since input accepts multiple files each object pushed onto files array filelist object.

so if want iterate through elements in files array can set function in change event handler:

var files = []; $("button:first").on("click", function(e) {     $("<input>").prop({         "type": "file",         "multiple": true     }).on("change", function(e) {         files.push(this.files);         iteratefiles(files);     }).trigger("click"); });   function iteratefiles(filesarray) {     for(var i=0; i<filesarray.length; i++){         for(var j=0; j<filesarray[i].length; j++){             console.log(filesarray[i][j].name);             // alternatively: console.log(filesarray[i].item(j).name);         }     } }

in iteratefiles() function wrote filesarray[i][j] isn't multidimensional array -- rather single dimensional array containing filelist objects behave much arrays...except can't delete/splice items out of them -- read-only.

for more info on why can't delete see: how remove file filelist

i see in body have {journalfullname} , not alter number anywhere on replace, (and other this) give error.

to avoid error ether alter parameter {{journalfullname}} ether sure replace because symbols {} wait have number within reflect parameter on format.

angularjs - Why does using wrap inside directive compile function cause infinite loop? -

i trying utilize wrap function within compile function of directive.

the next cause infinite loop , crash browser:

function compiler(telement, tattrs, transcludefn) {     var wrapper = angular.element('<div />');     telement.wrap(wrapper);       homecoming linker; }

why happening?

i'll guess... first time compiler function called, wraps element (i.e., element in html set directive attribute) within new <div></div>. angular treats new element , compiles it... finds directive, calls compiler function again, wraps again, , angular treats new element... advertisement infinitum.

Importing Text File in Java Constructor -

i not sure problems spawning from. have 2 classes, 1 called testfriends class , called guiapp class. in each of classes, object import file use. in testfriends class, import file in main method, parses , works nicely. in guiapp class, tried doing same thing, importing in constructor method , tells me file doesn't exists. both of files classes reside in same src folder , using:

bufferedreader in = new bufferedreader(new filereader(inputfile));

where inputfile string "friends.txt".

here 2 classes:

//this class works  public class temp {  public static void main(string[] args) throws parseexception {      seek {         system.out.println("hey");         bufferedreader in = new bufferedreader(new filereader("friends.txt"));  //create string buffer reading         string line = in.readline(); //reading first line         system.out.println(line);     }  grab (ioexception e) {         system.out.println("fail import.");     }  }  }   //////////the 1 below doesn't...  public class guiapp extends japplet{ //** panel **// private jpanel outerpanel;  //** button **// private jbutton button1;   /*  * constructor getting friends set  */ public guiapp() throws parseexception, filenotfoundexception{     bufferedreader in = new bufferedreader(new filereader("friends.txt"));//error line  }  /*  * create stuff  */ public void createstuff() {     outerpanel = new jpanel(); //create outer panel     button1 = new jbutton("click me");     outerpanel.add(button1,borderlayout.south); }   /*  * initialize stuff  */ public void init(){     createstuff(); //initialize create stuff     this.add (outerpanel);  }   }

any ideas why when both working in same directory, 1 can read while other can't?

thanks,

Is iOS removing the Content-MD5 HTTP header? -

i utilize web application that's returning content-md5 header in ios app, cannot retrieve header using [nshttpurlresponse allheaderfields] (whereas can see when utilize curl).

does know if ios deliberately removing header?

so i've figured out what's happened.

our saas provider has activated gzip default on non-production instances. mentioned in other threads, nsurlconnection supports gzip compression transparently , automatically send accept-encoding: gzip http header. when response received, nsurlconnection decompresses content , removes content-md5 header (because content-md5 hash of compressed data), why i'm not seeing in list of received headers.

objective c - subview from UIWindow and sending it back to UIwindow -

i have uiwebview loaded div, deed editor write. adding uiwebview sub view on uiwindow set frame equal total screen , hide uikeyboard, @ button method, need uiwebview uiwindow , sent uikeyboard. here code not working:

  keyboardwindowframe= nil;  (uiwindow *testwindow in [[uiapplication sharedapplication] windows]) {     if (![[testwindow class] isequal:[uiwindow class]])     {         keyboardwindowframe = testwindow;         [webviewforediting setframe:cgrectmake(5, 63, 310, 400)];         [webviewforediting.scrollview setcontentsize:cgsizemake(310, 400)];         [keyboardwindowframe addsubview:webviewforediting];          break;     }  } - (ibaction)keyboardbuttonselected:(id)sender {    [keyboardwindowframe sendsubviewtoback:webviewforediting];  //need send uiwebview uiwindow can write }

i think trying same thing , although question not particularly clear reply help.

it seems have view 'webviewforediting' want add together , bring in front end of keyboard. when click button want set view behind keyboard again.

i have tried using sendsubviewtoback code no joy.

in end though managed work using:

[[self view] exchangesubviewatindex: withsubviewatindex: ];

(credit goes sunny adapted question here)

i used next code below, switch between uiview , keyboard:

- (ibaction)togglebuttonpressed:(id)sender {      uiwindow * window = [uiapplication sharedapplication].windows.lastobject;      if (window.subviews.count == 1) {          [window addsubview:_menuview];     }     else {          [window exchangesubviewatindex: 0 withsubviewatindex: 1];     } }

i working 2 views (_menuview , keyboard) means check how many subviews window has create sure add together _menuview once.

then easy exchange 2 views.

even if had more subviews in window sure utilize modified version of this. long none of other views alter places exchanging them switch same 2 views.

note: aside. not sure if code works if called when keyboard not first responder. variable window using lastly object in window, keyboard if has been made first responder. might need tweaking working @ other times.

excel - Top third, next third of items by sales -

i have excel sheet shown below. need top third/ next 3rd items sales count. there way done in excel?

  item    count   1         100   2          90   3          80   4          60   5          55   6          50   7          45   8          35   9          25

dividing 3 buckets, 540/3 = ~180 items in each –

bucket 1 – items 1 , 2 (count = 190) bucket 2 – items 3, 4 , 5 (count = 195) bucket 3 - items 6, 7, 8, 9 (count = 155)

there multiple ways accomplish this. assuming item , count info in columns , b, shortest path utilize next formula in cell c2:

=round(3*sum($b$2:$b2)/sum($b$2:$b$10),0)

after entering c2, select cell , drag downwards right-bottom corner of cell way lastly row. note $ sign "missing" on purpose before sec 2. takes care of auto-fill behavior needed when dragging downwards corner.

if allowed utilize helper column, can create computationally more efficient method using next layout:

if want to, can hide column c. contains cumulative values of different sales counts. cell c1 set 0, cell c2 contains formula =$c1+$b2. column d approximates buckets using formula =round(3*$c2/$c$10,0) in cell d2, , 1 time again dragging downwards bottom-right corner. might improve approach if have many rows on sheet.

note both solutions yield same results. value in 1 or more buckets become 0, not right. can avoided using roundup in stead of round, since have not indicated want boundaries of buckets fall in different situations, thought leave exercise :-).

Need help to grouping php arrays to make it better -

first of all, grouping working sense dirty. need create looks clean , better. have next foreach

not sure type $topic['tid'] should careful when using non-consecutive numbers array keys.

ruby - Pretty print html output from Jekyll -

is there way pretty print html output jekyll?

for example, below snippet of html jekyll generates. notice how <p> tags have no indentation , have unnecessary line breaks after them.

      ...       <div id="content">  <p class="flush">post 1</p>  <p class="flush">post 2</p>  <p class="flush">post 3</p>         </div>       ...

i'm imagining alternative or plugin pretty print instead:

      ...       <div id="content">         <p class="flush">post 1</p>         <p class="flush">post 2</p>         <p class="flush">post 3</p>       </div>       ...

i suggest take 1 of tidy-makers , write own :tidy task in end of jekyll-specific task chain. or, easier:

desc "tidy jekyll output" task :tidy `find _site -name "*.html" -exec tidy {} \;` end

please note, neither newly created task nor plugin may found on net not applied on github pages, since have restricted policies run jekyll.

c# - Visual Studio autocomplete event handler with lambda format -

i'm on vs2012 , want utilize lambda format event handling, vs autocomplete tab key whenever type event subscrition via +=, e.g.:

vs autocompleted reference function inserts function:

txttitle.textchanged += txttitle_textchanged;  void txttitle_textchanged(object sender, textchangedeventargs e) {     .... }

is there way forcefulness autocomplete lambda format of:

txttitle.textchanged += (object sender, textchangedeventargs e) => { .... }

its huge pain have re-create , paste autocompleted non-lambda tighter lambda format.

you can create code snippet, have 1 creating lambda events.

here snippet if want seek (just save whatever.snippet) , import in vs (tools -> code snippet manager)

snippet:

video capture - Android: Record Screen Activity -

i planning record screen activity of user demo of 3 android applications created.

i think i've done research on google , play store , far, solutions saw either needed application not free, using google usb driver (which not compatible osx), or application required root.

i need application (either installed in android device or mac osx) can record screen activity of android device free, not require root, , not require intermediate hardware in order work.

thank you.

as of android 4.4, there screen recording feature accessible via adb.

http://developer.android.com/tools/help/adb.html#screenrecord

the screenrecord command shell utility recording display of devices running android 4.4 (api level 19) , higher. utility records screen activity mpeg-4 file, can download , utilize part of video presentation. utility useful developers want create promotional or training videos without using separate recording device.

How to calculate moving average in Python 3? -

let's have list:

y = ['1', '2', '3', '4','5','6','7','8','9','10']

i want create function calculates moving n-day average. if n 5, want code calculate first 1-5, add together , find average, 3.0, go on 2-6, calculate average, 4.0, 3-7, 4-8, 5-9, 6-10.

i don't want calculate first n-1 days, starting nth day, it'll count previous days.

def moving_average(x:'list of prices', n): num in range(len(x)+1): print(x[num-n:num])

this seems print out want:

[] [] [] [] []  ['1', '2', '3', '4', '5']  ['2', '3', '4', '5', '6']  ['3', '4', '5', '6', '7']  ['4', '5', '6', '7', '8']  ['5', '6', '7', '8', '9']  ['6', '7', '8', '9', '10']

however, don't know how calculate numbers within lists. ideas?

there great sliding window generator in old version of python docs itertools examples:

from itertools import islice  def window(seq, n=2):     "returns sliding window (of width n) on   info iterable"     "   s -> (s0,s1,...s[n-1]), (s1,s2,...,sn), ...                   "     = iter(seq)     result = tuple(islice(it, n))     if len(result) == n:         yield result         elem in it:         result = result[1:] + (elem,)         yield result

using moving averages trivial:

from __future__ import  partition  # python 2  def moving_averages(values, size):     selection in window(values, size):         yield sum(selection) / size

running against input (mapping strings integers) gives:

>>> y= ['1', '2', '3', '4','5','6','7','8','9','10'] >>> avg in moving_averages(map(int, y), 5): ...     print(avg) ...  3.0 4.0 5.0 6.0 7.0 8.0

to homecoming none first n - 1 iterations 'incomplete' sets, expand moving_averages function little:

def moving_averages(values, size):     _ in range(size - 1):         yield none     selection in window(values, size):         yield sum(selection) / size

you need tell form take multiple files this

{{ form_widget(form.file, { 'attr': { 'multiple': 'multiple' } }) }}

or this

{{ form_widget(yourform.file, { 'full_name':                                  yourform.file.get('full_name') ~ '[]' }) }}

read here https://github.com/symfony/symfony/issues/1400

this way can select , upload multiple files @ once.

math - What does squaring a transformation mean? -

i trying understand solution read exercise defines logarithmic time procedure finding nth digit in fibonacci sequence. problem 1.19 in construction , interpretation of computer programs (sicp).

spoiler alert: solution problem discussed below.

fib(n) can calculated in linear time follows: start = 1 , b = 0. fib(n) equals value of b. initially, n = 0, fib(0) = 0. each time next transformation applied, n incremented 1 , fib(n) equals value of b.

<-- + b b <--

to in logarithmic time, problem description defines transformation t transformation

a' <-- bq + aq + ap b' <-- bp + aq

where p = 0 , q = 1, initially, transformation same 1 above.

then applying above transformation twice, exercise guides express new values a'' , b'' in terms of original values of , b.

a'' <-- b'q + a'q + a'p = (2pq + q^2)b + (2pq + q^2)a + (p^2 + q^2)a b' <-- b'p + a'q = (p^2 + q^2)b + (2pq + q^2)a

the exercise refers such application of applying transformation twice "squaring transformation". right in understanding?

the solution exercise applies technique of using value of squared transformations above produce solution runs in logarithmic time. how problem run in logarithmic time? seems me every time utilize result of applying squared transformation, need 1 transformation instead of two. how successively cutting number of steps in half every time?

the solution schemewiki.org posted below:

 (define (fib n)     (fib-iter 1 0 0 1 n))   (define (fib-iter b p q count)     (cond ((= count 0) b)           ((even? count)            (fib-iter                      b                      (+ (square p) (square q))                      (+ (* 2 p q) (square q))                      (/ count 2)))           (else (fib-iter (+ (* b q) (* q) (* p))                           (+ (* b p) (* q))                           p                           q                           (- count 1)))))    (define (square x) (* x x))

the exercise refers such application of applying transformation twice "squaring transformation". right in understanding?

yes, squaring transformation means applying twice or (as case in solution exercise) finding transformation equivalent applying twice.

how problem run in logarithmic time? seems me every time utilize result of applying squared transformation, need 1 transformation instead of two. how successively cutting number of steps in half every time?

squaring given transformation enables cutting downwards number of steps because values of p , q grow much faster in squared transformation in original one. analogous way can compute exponents using successive squaring much faster repeated multiplication.

so how successively cutting number of steps in half every time?

this in code given. whenever count even, (/ count 2) passed count on next iteration. no matter value of n passed in on initial iteration, on alternating iterations (worst case).

you can read blog post on sicp exercise 1.19: computing fibonacci numbers if want see step-by-step derivation of squared transformation in exercise.

sql - how to fix a double LEFT JOIN in a trac report -

we utilize customized version of trac people can give scores bugs based on 2 criteria, allow phone call them severity , importance.

for simplicity, allow database contains next tables:

table ticket

id | title           | reporter 1  | sql injection   | torvalds 2  | buffer overflow | linus 3  | localization    | bofh

table votes

ticket_id | value | type       | voter 1         | 4     | severity   | linus 1         | 2     | severity   | torvalds 1         | 3     | severity   | bofh 1         | 4     | importance | linus 1         | 3     | importance | torvalds 2         | 4     | severity   | linus 2         | 2     | severity   | torvalds 2         | 1     | importance | linus 2         | 1     | importance | bofh 3         | 1     | importance | linus

so instance first row means user linus suggested 4 severity score of ticket #1.

now have next sql query in trac study utilize average scores:

select t.title, t.reporter, avg(vs.value), avg(vi.value), count(vs.value), count(vi.value) ticket t left  bring together votes vs on vs.type = 'severity'   , vs.ticket_id=t.id left  bring together votes vi on vi.type = 'importance' , vi.ticket_id=t.id;

in hopes, should homecoming table next values:

title | reporter | severity avg | importance avg | number of sev. votes | number of imp. votes sql injection | torvalds | 3 | 3.5 | 3 | 2

thus telling me how many people voted ticket , votes are.

however, due way left join works, entries cartesian product of severity , importance votes, averages still valid, while both counts set 3x2=6 instead of right value.

is there simple way prepare query, returns want?

combine case statements aggregate functions:

select    t.title,    t.reporter,    sum(case when v.type = 'importance' 1 else 0 end) count_imp,   sum(case when v.type = 'severity' 1 else 0 end) count_sev,   sum(case when v.type = 'importance' v.value else 0 end) /      count_imp avg_imp,   sum(case when v.type = 'severity' 1 else 0 end) /      count_sev avg_sev    ticket t   left  bring together votes v    on v.ticket_id = t.id;

if trac sql doesn't allow re-use aliases count_imp , count_sev repeat statements in average calculation columns.

c# - REGEX character Set substitution -

i need regex pattern allow me substitute characters 1 set corresponding characters in set. example: set [abcdefg], should replaced set [1234567]... in string of "bag", want replacement "217".

regex regx = new regex("([abcdefg])([1234567])"); string result = regx.replace("bag", "$1$2");

my result same source. should replace pattern be?

something work much improve regex:

var fromcharacters = "abcdefghijklmnopqrstuvwxyz"; var tocharacters = "12345678901234567890123456";  var mystring = "bag";  var sb = new stringbuilder(mystring.length); (int = 0; < mystring.length; ++i) {     sb.append(tocharacters[fromcharacters.indexof(mystring[i])]); }  sb.tostring().dump();

you similar if want, example, 'j' turn '10', need array of strings instead of beingness able utilize string array of chars.

i'm not sure how regex, know shouldn't.

is there way line ending glyphs in visual studio 2012?

the next screen shot (from notepad++) show want (the cr lf part):

you might want check out extension: end of line rolf w. rasmussen. current binary version displays cr , lf identifiers @ end of line time, source version ties vs's "view whitespace" menu option.

it's visual studio 2013, it's open source , should straightforward recompile vs2012 compatible plugin

c# - Regex to match string delimited with two types of delimiter -

i don't understand how regex expressions set together, here's question.

i have delimited string 1,3;5,1;6,4 , on. have here storing shopping cart products ids , volumes. 1,3 mean have product id "1" , quantity 3. products (with volumes) delimited ";".

what need set regex validate such string. positive numbers allowed limitation let's 1 10000.

does has solution that?

this regex pattern matches on semicolon-delimited number pairs, comma separates members of each pair, , each number between 1 , 10000:

^([1-9]\d{0,3}|10000),([1-9]\d{0,3}|10000)(;([1-9]\d{0,3}|10000),([1-9]\d{0,3}|10000))*$

there must @ to the lowest degree 1 pair. if there 1 pair, no semicolon follows it. semicolons should nowadays between neighboring pairs.

mod rewrite - mod_rewrite and .htaccess: Can my RewriteRule substitution be a subfolder in DocumentRoot's parent folder? -

thanks help in advance.

here's , trying accomplish:

i have static files in /home/username/code/project/static/ my document root /home/username/public_html/ (which .htaccess file is).

i'm trying utilize next in .htaccess file (i have no access httpd.conf):

rewriterule ^(static/.*)$ /home/username/code/project/static/ [l]

but if understand mod_rewrite's documentation correctly (see below), "/home/username/code/project/static/" treated either file-system path relative document root or url path, not absolute file-system path intended.

i tried using "~/code/project/static/" , "../code/project/static/", got internal server error when trying visit page (yes, i'm bit of noob).

so question is: there way substitution of rewrite rule used in .htaccess context absolute file-system path rather path relative documentroot?

here's extract mod_rewrite documentation reference (can found in total here: http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule):

for example, if specify substitution string of /www/file.html, treated url-path unless directory named www exists @ root or file-system (or, in case of using rewrites in .htaccess file, relative document root), in case treated file-system path.

any help much appreciated :)

thanks!

one way accomplish you're trying create symlink within public_html points static /home/username/code/project/static/. requires followsymlnks alternative detailed in options directive documentation may not allowed within total apache configuration, out of control.

a improve approach reverse link - create public_html/static maintain real files , create /home/username/code/project/static symlink public_html/static. avoids need specific .htaccess rules. since seems want create files under directory publicly-accessible anyways, it's improve security-wise since keeps publicly-accessible files under same directory construction , avoids potential security issues arise allowing symlinks go within web root other areas of file system.

Adding some python flavor to C++ -

curly braces for(int i=0; i<10; i++) { line 1 line 2 } if (something) { line 3 line 4 } else if(something) { line 5 line 6 line 7 } else { line 8 line 9 line 10 }

i lazy typist , in recent years i've developed dislike curly braces in c++. not think unnecessary; can't live without them in long pieces of code. when branch of code contains 3 5 lines, increased indentation lone seems sufficient in making context clear, , curly braces don't seem much more taking precious screen space (especially when utilize vertical splits) , requiring me press more keys, which, owing not-so-convenient positions on keyboard, add together more strain fingers.

so, i'm thinking of doing preprocessor allow me utilize python-flavored c++, this:

for(int i=0; i<10; i++)     line 1     line 2  if (something)     line 3     line 4 else if(something)     line 5     line 6     line 7 else     line 8     line 9     line 10

so create curly braces optional in short branches of code, , doing code becomes cleaner. if have lot of functions consist of no more 8 lines, getting rid of curly braces create huge difference me. things seem more compact, clean; , beingness able see more useful code in 1 screen somehow makes me sense better. people kind of thing below thankful well:

void blahbalh(){ code... }

apparently people started doing decades ago sake of screen space. now, wouldn't improve if curly braces become optional? is, utilize them when code contained becomes relatively long.

symbols in general

to add together more python flavor c++. think braces surrounding conditions can done away with. looks really different c++, after got used python found quite elegant:

if something:     line 3     line 4 elif something:     line 5     line 6     line 7 else:     line 8     line 9     line 10

generally, i've found python tends utilize far fewer symbols, thing:

symbols cause more finger strains plain text, because of relatively inconvenient positions on our keyboards , because of need press shift (qwerty , dvorak same here) since alphanumerical keys easier press, can type faster if avoid using symbols. , experience sense more natural flow when don't have press shift key.

so have more plain-text operators, using and in place of &&, , or in place of ||, etc. , can have python-styled loops, easier type

what guys think of python-flavored c++? suggestions?

i'm thinking of doing preprocessor simple source-to-source transformation. looks easiest way go without having define new language.

i lazy typist , in recent years i've developed dislike curly braces in c++ ... , curly braces don't seem much more taking precious screen space

write code this, , switch ide types braces you. can go on write code rest of understand.

for (int i=0; < 10; i++) {     line 1     line 2 }  if (something) {     line 3     line 4 } else if (something) {     line 5     line 6     line 7 } else {     line 8     line 9     line 10 }

my original replace code is.

rttextarea.rtf = rttextarea.rtf.replace(oldtext, newtext);

but problem replaces occurence of words instead of required word e.g origianl word :- hello name serak , in state of israel replace() -- whole word chages "are serak , in arereal"

is there anyway can include status or match whole word? working environment c#.

use regular expressions. in illustration \b represents word boundary.

var regexp = new system.text.regularexpressions.regex(@"\bis\b"); rttextarea.rtf = regexp.replace(rttextarea.rtf, "are");

scala - Mapper versus Record/Squeryl -

i start first project in lift framework , have decide persistence library choose. utilize relational backend both mapper , record may come in play.

in case of mapper - thing miss ability command queries beingness sent rdbms - when comes more complicated queries solved joins, aggregation etc in sql. take next illustration - let's have next 2 entities:

class baseproduct extends longkeyedmapper[baseproduct] idpk {   // fields } object baseproduct extends baseproduct longkeyedmetamapper[baseproduct]  class myproduct extends longkeyedmapper[myproduct] idpk {   // fields   object  base of operations extends mappedlongforeignkey(this, baseproduct) } object myproduct extends myproduct longkeyedmetamapper[myproduct]

where myproduct 1 of specialization of baseproduct entity. there one-to-one relation between these entities. best possibility i've come query exact myproduct baseproduct query this:

myproduct.findall(precache(myproduct.base))

which issues 2 queries (moreover afraid not able command fields of myproduct entity want select.

enough bad mapper library. main concern record/squeryl api fact lacks proto-classes nowadays around mapper api. there close functionality of these classes record? possible access database specific features in squeryl (eg. geometrical queries in postgresql)?

are there other pros , cons either of these layers? or there other abstraction layer deserve attending if want have decent typesafe encapsulation of communication database , provide decent command on queries (i used issuing queries straight using pdo layer in php - don't want such direct querying interface possibility of having command on queries great) integration lift framework advantage.

thank you!

we've been using squeryl lift quite while , have been happy it. based on case above, in current release version of squeryl (0.9.5), like:

class baseproduct(id:long, more fields) extends keyedentity[long] {  }  class myproduct(id:long, more fields) extends keyedentity[long] {  }

then, have schema defines relationships (i assuming joined on id field):

val baseproducts = table[baseproduct]("base_products") val myproducts = table[myproduct]("my_products") val myproductstobaseproducts =    onetomanyrelation(myproducts, baseproducts).via((mp, bp) =>     mp.id === bp.id)

to query both records, like:

from(myproducts, baseproducts) ( (mp, bp) => where(mp.id === bp.id , mp.id === lookupval) select(bp, mp) )

the query above homecoming tuple of (baseproduct, marketproduct) single sql select.

you can utilize relationship retrieve related item, such adding method myproduct:

def baseproduct = myproductstobaseproducts.left(this)

however, illustration mapper, issue sec query. making database specific queries, there & operator allow evaluate expressions @ server. if function not available in squeryl can create custom functions.

overall, have found squeryl flexible , great hybrid between orm , straight sql. has performed remarkably , have not found many places squeryl prohibited me getting @ database functionality needed. gets easier next version, 0.9.6 have lot more flexibility custom types.

sql - Proper populating of dropdown list in asp.net dynamically -

i newbie in asp.net, want inquire more proper in terms of populating dropdown list in asp.net? using datasource or using sqldatareader , loop.

i using sqldatareader , loop, here sample code:

for = 1 20             etc.commandtext = "select classification schemaitemdetails.assetclassification ac_id = " & & ""             dim dr sqldatareader = etc.executereader             while (dr.read())                 ddoneclassification.items.add(dr.getstring(0))             end while             dr.close()         next

is there difference in using sqldatasource , one?? never utilize sqldatasource populating dropdown.

from point of view easiest , best solution set dropdownlist's datasource property. in case, required job done behind scene , neednd't think of synchronization info between db server , web server.

also, if you, modify sql single request sent db server, i.e.

"select classification schemaitemdetails.assetclassification ac_id between 1 , 20"

private void printdocument_printpage(object sender, printpageeventargs e) {     graphics graphic = e.graphics;      font font = new font("courier new", 12);     float fontheight = font.getheight();     int startx = 10;     int starty = 10;     int offset = 0;      float pagewidth = e.pagesettings.printablearea.width;     float pageheight = e.pagesettings.printablearea.height;      foreach (string line in textrichtextbox.lines)     {         graphic.drawstring(line, font, new solidbrush(color.black), startx, starty + offset);         offset += (int)fontheight;// + 5          if (offset >= pageheight - (int)fontheight)         {             e.hasmorepages = true;             offset = 0;         }     }     e.hasmorepages = false; }

you using api wrong, the doc says:

in printpage event handler, utilize graphics property of printpageeventargs class , document contents calculate line length , lines per page. after each page drawn, check see if lastly page, , set hasmorepages property of printpageeventargs accordingly. printpage event raised until hasmorepages false. also, create sure printpage event associated event-handling method.

you can't set hasmorepages in loop, on exit of callback. callback called until set hasmorepages false

servicestack - Razor exceptions -

i have undoubtedly set wrong exceptions thrown razor templates though there no problem templates. these fixed doing build.

if have error in template popup asking me debug in vs, of course of study not allow me debug template.

errors in log not helpful (see below).

is possible both avoid spurious errors , improve info when there problem?

servicestack.razor.templating.templatecompilationexception: unable compile template. check errors list details.    @ servicestack.razor.templating.templateservice.createtemplate(string template, type modeltype)    @ servicestack.razor.templating.templateservice.compile(viewpageref viewpageref, string template, type modeltype, string name)    @ servicestack.razor.templating.templateservice.compile(viewpageref viewpageref, string template, string name)    @ servicestack.razor.viewpageref.compile(boolean force)

i having similar problems. found "easiest" way find out error was, download of service stack, build debug version of razor libary , link project. set break point in servicestack.razor.templating.templateservice.createtemplate method , able see total exception details. there learnt had included import in razor page not referenced in project.

since solved it's been reliable.

php - CRUD Resource incl Sub-Resource in MANY_MANY relation with RESTfull JSON-API -

i utilize yii framework web-application restfull json-api , crud operations. api utilize restfullyii extension. there alternative?

there 3 tables (user, event , event_participant) many_many relation. relation in event model:

public function relations() {      homecoming array(         'participants' => array(             self::many_many,             'user',             'event_participant(studiobooking, user)'         )     ); }

i want utilize crud operations crud event user sub-resource in 1 request. works resource sub-resource. want save/update/delete resource incl. sub-resource, illustration post request data:

{     "event": "eventname",     "start": "2013-02-17 14:30:00",     "end": "2013-02-17 16:00:00",     "participants": [ {         "id": "2"     },{         "id": "3"     }] }

this should create new event in event table , new id event participant ids in "event_participant" table. possible yii framework?

you'll have come own code this, relatively straight forward. here's example. note: "coded" in stackoverflow editor, not production ready, tested code :)

ruby - Unable to use bourbon functions with sass (sass -r bourbon.rb fails) -

i having problem compiling sass files functions such linear-gradient or box-shadow. getting same issue here https://github.com/thoughtbot/bourbon/issues/68 resulting css jumble of false's.

i not working on rails project, thought might have include bourbon.rb file library when doing sass --watch, not working me:

sass --watch .:.. --r ./bourbon/lib/bourbon.rb loaderror: cannot load such file -- bourbon/generator    utilize --trace backtrace.

no such file load -- rubygems (loaderror) here says might indicate have several versions of ruby installed, , which -a ruby showed both rbenv 1.9.3-p327 /usr/bin/ruby (i stil unclear difference is). anyway, moved .rbenv backup , supposedly have 1 version of ruby. tried specifying rubygems path

echo $rubylib /usr/lib/ruby/1.9.1/rubygems

but still getting same error when trying include bourbon.rb file sass --watch.

elise, version of bourbon using? $bourbon -v

since bourbon 3.0, no longer required pass --r ./bourbon/lib/bourbon.rb flag sass --watch command.

please read new installation instructions here: http://bourbon.io/

Provide an HTML page with JS with node.js and express -

i trying serve html page linked js script using node.js , express. server provide page:

var express = require("express"); var app2 = express(); app2.get('/', function(req, res) {    res.sendfile('./index.html'); }); app2.listen(process.env.vcap_app_port || 3000);

and page:

<!doctype html> <html> <head>     <title>demo</title> </head> <body>     <h1>demo</h1>     <script src="/js/socket.io.js"></script>     <script src="/js/codice.js"></script> </body>

as can see have 2 js scripts in js folder not loaded when launch page. can do?

what place public resources (javascript files, css files, images etc) in directory (express names public default) , utilize express.static middleware in app.configure call:

app.configure(function () {     // various other middleware functions...     app.use(express.static(path.join(__dirname, "public"))); });

this runs static file server homecoming file within public directory. currently, browser making request js files, express server doesn't know them. time out.

if generate initial state of app global express executable (available if installed express via npm globally), set of you.

operators - Precedence of cast in c# -

this question has reply here:

cast operation precedence in c# 2 answers

what precedence of cast in c#? illustration in next code, z less or equal two?

double x = 4.5; double y = 2.1; double z = (int) x / y;

the cast beats binary operators binding. hence (int)x / y means ((int)x)/y.

on other hand, should prefer readable code clever code, since don't know should write next instead:

((int)x) / y

note brackets free, , create code more readable.

One or two keyspaces in Cassandra for a different kind of data of the single application -

in project utilize cassandra analytics , mysql store data. see cassandra fit info well.

my question is: should create new keyspace info or should utilize keyspace exists used analytical data? should take business relationship when making such decision?

my stack python (django) + pycassa, cassandra 1.2.

keyspace high level grouping of similar column families. there no hard , fast rules, , important implications of either decision relate specific client library's api. personally, create new keyspace when want separation of concerns data. it's analogous creating different database in relational db.

android - SherlockActionBar: Export signed apk, then Eclipse crashes :( -

today finished testing new android app..

i utilize sherlockactionbar.

import /library

my os ubuntu 12.10 64bit..

i can build .apk eclipse , app runs on android 2.3.3(mobile) , android 4.0(tablet).

but when seek to: android tools -> export signed application package, eclipse crashes :(

i error:(before export/crash)

invalid zip archive: /home/voidcode/ubuntu one/workspace/jakewharton-actionbarsherlock-e5c2d1c/library/bin/library.jar

this error log find in eclipse-folder after crash: http://paste.ubuntu.com/1677938/

my androidmanifest.xml this:

<uses-sdk android:minsdkversion="4" android:targetsdkversion="15" />

and project.properties this:

# file automatically generated android tools. # not modify file -- changes erased! # # file must checked in version  command systems. # # customize properties used ant build  scheme edit # "ant.properties", , override values adapt script # project structure. # # enable proguard shrink , obfuscate code, uncomment (available properties: sdk.dir, user.home): #proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt  # project target. target=android-14 android.library.reference.1=../jakewharton-actionbarsherlock-e5c2d1c/library

you may want check couple of things in project.

your project.properties file targets android api14, manifest targets api15. these should same sherlock actionbar works on api7+. may issue actually. seek changing android:minsdkversion="4" android:minsdkversion="7" obviously not allow prior android 2.1, you'll still target 100% of ecosystem.

if doesn't work, i've had lots of problem , exporting packages solutions random.

my general solution disable auto build, clean , manually build library projects.

for example

under project menu uncheck build automatically then project > clean... on window, uncheck start build immediately choose clean projects , click ok select sherlock actionbar project do project > build project (not build all). this build 1 library do library projects have included. click now, export project signed apk.

that works me , stops lot of unexplained export issues.

asp.net mvc 3 - Current user identity in ObjectContext.SavingChanges -

i using objectcontext.savingchanges event update createddate/updateddate columns based on object state this

partial void oncontextcreated() {    //extension of command timeout avoid processing problems.    commandtimeout = 600; //time in seconds     this.savingchanges += new eventhandler(entities_savingchanges); }  protected void entities_savingchanges(object sender, eventargs e) {    var addedobjects = this.objectstatemanager.getobjectstateentries(system.data.entitystate.added);    foreach (var addedobject in addedobjects)    {       var propertyinfo = addedobject.entity.gettype().getproperty("createddate");       if (propertyinfo != null)       {          propertyinfo.setvalue(addedobject.entity, datetime.utcnow, null);       }     }      var modifiedobjects = this.objectstatemanager.getobjectstateentries(system.data.entitystate.modified);     foreach (var modifiedobject in modifiedobjects)     {        var propertyinfo = modifiedobject.entity.gettype().getproperty("updateddate");        if (propertyinfo != null)        {           propertyinfo.setvalue(modifiedobject.entity, datetime.utcnow, null);        }     } }

i have 2 more columns createduser , updateduser.

is there way update using current user name context?

ofcource, system.httpcontext.current null here separate class library project, access through wcf service.

if code resides in wcf service consume asp.net mvc application send current username parameter method invoking.

android - ViewFlipper vs AdapterViewFlipper -

could explain practical differences between viewflipper , adapterviewflipper. including when utilize 1 , not other.

i have been using viewflipper months in custom cursor adapter , origin think used wrong approach albeit works.

with viewflipper, typically declare children front, , there no recycling concept.

with adapterviewflipper, utilize adapter, listview, spinner, etc., children determined on fly , views representing children can recycled.

for small, static content, viewflipper simpler. also, adapterviewflipper added in api level 11 (iirc) , hence not work on older versions on android.

you setting item datatemplate contextmenuservice.contextmenu , there no actual content. need have content displayed there. also, have items in list?

move contextmenuservice.contextmenu in 1 main template - splitting (for unknown reason). remove datatemplate declaration in listbox command , utilize pre-defined style.

.net - Multi threading Concept in Oracle pl/sql -

i created procedure, takes input in form of array, beingness passed .net web application.

in procedure: open cursor containing info in table, fetching info cursor row row , apply validation rules on it.

for each row need multiple hits db (almost containing nested queries); if info validation fails update remarks field in same table (by using update query immediately), , if validation successful inserting/updating info in other table.

i tried on 0.25 1000000 records, , noticed takes more 1 hr process it.

i need improve performance of stored procedure. please allow me know how accomplish this.

i have thought this.

making multiple sets of record (10 k in each set) , process each set way utilize multi threading.

is possible? if yes how?

very likely, procedure can made faster utilize of pl/sql batch processing capabilities. run code in parallel, @ dbms_job , dbms_scheduler packages. also, check if parts of code can speed parallel query and/or parallel dml. line line slowest thing, if used explicit cursor.

perl - catalyst consistent url format with trailing slash -

i'm developing catalyst application , having problem way catalyst interprets urls.

let's in our catalyst application have controller account. if case, catalyst interpret

http://mydomain.com/account , http://mydomain.com/account/

as same url index action.

however, seo , linking purposes (and consistent overall) forcefulness catalyst recognize 1 format , stick it.

i've found 1 module seems built this: catalyst::plugin::sanitizeurl, it's documentation says should set

use catalyst 'sanitizeurl';

in myapp.pm , handle you.

however, whenever utilize error:

bad request

on every page load. know of simple way have catalyst utilize 1 format?

the simple way forcefulness catalyst utilize 1 format without trailing slash add together method myapp.pm:

sub begin :private {     ($self, $c) = @_;     @path = split "/", $c->req->path, -1;     $c->detach('default') if @path , (pop @path eq ''); }

it redirect on 'default' method a.k.a page 404 if uri ends slash on request.

i'm hoping can utilize perl doing equivalent of this:

you should search around dump_peer_certificate() method net::ssleay module.

see http://www.perlmonks.org/?node_id=70620 , http://metacpan.org/pod/net::ssleay

the problem when build , images shown want save current shown image disk. need current fragment imageview can't because fragment.getview() null, activity associated fragment null , can't figure out why it. here code see if help here:

this fragment:

public class imageviewurlfragment extends fragment  {     string _url;      @override     public view oncreateview(layoutinflater inflater,             viewgroup container, bundle savedinstancestate)      {         //  lastly 2 arguments ensure layoutparams inflated         // properly.         view rootview = new imageviewurl(getactivity(), _url);           homecoming rootview;     }      public void setimageurl(string imgurl)     {         _url=imgurl;     } }

and adapter:

public class imageviewurlcustomadapter extends fragmentstatepageradapter  {     list<string> _urls=new arraylist<string>();      public imageviewurlcustomadapter(fragmentmanager fm)      {         super(fm);     }      @override     public fragment getitem(int i)      {         imageviewurlfragment fragment = new imageviewurlfragment();         fragment.setimageurl(_urls.get(i));           homecoming fragment;     }      public string getitemurl(int i)     {          homecoming _urls.get(i);     }      @override     public int getcount() {          homecoming _urls.size();     }      @override     public charsequence getpagetitle(int position) {          homecoming "object " + (position + 1);     }      public void addimageurl(string url)     {         _urls.add(url);     } }

and main activity, notice comment get:

public class mainactivity extends fragmentactivity  {     imageviewurlcustomadapter _iva=null;     viewpager _vp=null;      @override     protected void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          _iva = new imageviewurlcustomadapter(                         getsupportfragmentmanager());         _iva.addimageurl("http://upload.wikimedia.org/wikipedia/commons/b/b4/saturn_(planet)_large.jpg");         _iva.addimageurl("http://planetthreesixty.com/sites/default/files/planet.jpg");          _vp = (viewpager) findviewbyid(r.id.viewpager);         _vp.setadapter(_iva);     }       @override     public boolean oncreateoptionsmenu(menu menu)      {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.activity_main, menu);          homecoming true;     }      @override     public boolean onoptionsitemselected(menuitem item)      {         if(item.getitemid()==r.id.savetosd)         {             int index= _vp.getcurrentitem();             fragment fragment=_iva.getitem(index);              //this need fragment view, returns null                     view view= fragment.getview();             imageview iv=(imageview)view.findviewwithtag("imageview");             bitmap bmp=iv.getdrawingcache();           }            homecoming super.onoptionsitemselected(item);     } }

sorry long sources, have cleaned could, wanted nowadays playing parts. guess hapenning?

thanks in advance.

so need current fragment imageview can't because fragment.getview() null, activity associated fragment null , can't figure out why it.

that happening because you're expecting _iva.getitem(index); homecoming fragment viewpager uses page corresponding specified index. not happen viewpager has called getitem method fragments needs , after phone call getitem method new imageviewurlfragment instance. new instance isn't tied activity(getactivity() returns null) , view wasn't created.

as utilize fragmentstatepageradapter seek code below visible fragment:

if (item.getitemid()==r.id.savetosd) {      int index = _vp.getcurrentitem();      fragment fragment = _vp.getadapter().instantiateitem(_vp, index);      //...

php - Base64 Over HTTP POST losing data (Objective-C) -

i have http post request , base64 encoding library, encode image b64 send on http via post method.

i output base64 xcodes console, re-create , paste , works perfectly. although base64 store within database (mongodb, plain text file etc) comes out corrupt on other end.

working version (copied , pasted xcode): http://dontpanicrabbit.com/api/working.php broken version (from mongodb database): http://dontpanicrabbit.com/api/grabimage.php

if view source you'll notice same there added whitespace broken version.

the objective-c code using is:

myimage.image = [info objectforkey:uiimagepickercontrolleroriginalimage];      nsdata *imagedata = uiimagejpegrepresentation(myimage.image, 0);      [base64 initialize];     nsstring *encoded = [base64 encode:imagedata];      nsstring *urlpost = encoded;     //nslog(@"%@",encoded);      nsstring *varyingstring1 = @"picture=";     nsstring *varyingstring2 = urlpost;     nsstring *post = [nsstring stringwithformat: @"%@%@", varyingstring1, varyingstring2];     nslog(@"%@", post);     //nsstring *post = @"image=%@",urlpost;     nsdata *postdata = [post datausingencoding:nsasciistringencoding allowlossyconversion:yes];      nsstring *postlength = [nsstring stringwithformat:@"%d", [postdata length]];      nsmutableurlrequest *request = [[nsmutableurlrequest alloc] init];     [request seturl:[nsurl urlwithstring:@"url/api/insertimage.php"]];     [request sethttpmethod:@"post"];     [request sethttpbody:postdata];     nsdata *returndata = [nsurlconnection sendsynchronousrequest: request returningresponse: nil error: nil];     nsstring *strresult = [[nsstring alloc] initwithdata:returndata encoding:nsutf8stringencoding];

php -> mongodb storage

<?php      seek {       // open connection mongodb server       $conn = new mongo('localhost');        // access database       $db = $conn->dablia;        // access collection       $collection = $db->images;        // insert new document       $item = array(         'picture' => $_post['picture']       );       $collection->insert($item);       echo 'inserted document id: ' . $item['_id'];        // disconnect server       $conn->close();     }  grab (mongoconnectionexception $e) {       die('error connecting mongodb server');     }  grab (mongoexception $e) {       die('error: ' . $e->getmessage());     } ?>

output code:

<?php  seek {   // open connection mongodb server   $conn = new mongo('localhost');    // access database   $db = $conn->dablia;    // access collection   $collection = $db->images;    // execute query   // retrieve documents   $cursor = $collection->find();    // iterate through result set   // print each document   foreach ($cursor $obj) {     echo '<img src="data:image/jpeg;base64,'.trim($obj['picture']).'">';   }    // disconnect server   $conn->close(); }  grab (mongoconnectionexception $e) {   die('error connecting mongodb server'); }  grab (mongoexception $e) {   die('error: ' . $e->getmessage()); } ?>

i have no thought why seem corrupting on post?

the problem suggested in first comment. is, base64 encoded info can contain '+' characters. in x-www-form-urlencoded info receiver knows '+' encoding of space character. since aren't url encoding base64 value, instances of '+' cause info corrupted when received.

the '+' characters in initial info turning ' ' when received , stored. when output value, invalid base64 encoded data.

if examine source of working vs. non-working examples you'll see whitespace exists there '+' in original base64 encoded value. newlines you're seeing because whatever you're viewing source in wrapping lines @ ' ' character.

in ios code need encode base64 encoded value, in case need percent encode '+' characters.

edit add, in response comment:

post = [post stringbyreplacingoccurrencesofstring:@"+" withstring:@"%2b"];

Where to keep editable config file for Android application? -

i want config file similar config.xml in .net can edit manually device. have info can modified. 1 way figured out maintain file in sdcard in xml form , read that. question approach whether reading xml sdcard in android app slow downwards performance?

is there other way store config file can changed later?

you consider using sharedpreferences. not sure purpose of config.xml in .net is, if saving info can modified looking for, sharedpreferences sounds solution.

of course, mentioned above, not knowing config.xml for, taking stab suggestion. allow me know if not looking for. delete reply before down-vote barrage begins. ;-)

in case fits bill, here few tutorials started.

ruby on rails 3.2 - ActiveAdmin member_action gives 401 Unauthorized response -

i building rails app using active_admin 0.5.1.

in app/admin/plays.rb defined admin resource this:

activeadmin.register play member_action :upload, :method => :post ... end def index ... end end

note added non-standard upload-action described here: http://activeadmin.info/docs/8-custom-actions.html

now whenever phone call index action, works fine. when post fellow member action :upload though, 401 response:

started post "/admin/plays/1/upload.js" 127.0.0.1 @ 2013-02-13 18:46:36 +0100 processing admin::playscontroller#upload js   parameters: {...} warning: can't verify csrf token authenticity   adminuser load (0.4ms)  select "admin_users".* "admin_users" "admin_users"."id" = 1 limit 1    (0.1ms)  begin transaction    (0.0ms)  commit transaction completed 401 unauthorized in 7ms

furthermore after getting error, admin user logged out.

what missing here? expecting actions defined via member_action work standard actions.

found reason.

"warning: can't verify csrf token authenticity" kind of give-away.

you need add together authenticity_token param ajax upload request create devise happy.

i still wish devise have given more detailed hint on happened in detail.

Dialogs don't pause thread - Android Logic -

i'm having bit of confusion logic of code. i'm doing displaying dialog user using showdialog (which know depreciated) , select, drawing icon touched.

my question is: "how programme "pause" while user picking selection, next code doesn't called , drawing isn't done after press ok.

edit: forgot mention - on main ui thread, haven't got lot of experience dealing threads have couple of asynctasks in program. there point in making new thread handle touch , drawing functions?

private void touch_start(float x, float y) { // on finger touchdown             // check touch mode             if (addobjectmode == true) {                 //drawingareaview method  add together edittext box @ position x,y                 ix = (int) (math.round(x));                 iy = (int) (math.round(y));                 mx = (int) (math.round(x));                 = (int) (math.round(y));                 myrect.set(ix, iy, mx, my);             } else if (addappliancemode == true) {                 // code draw appliance icon @ mx, (with offset icon centered)                 maketoast("start drawing appliance @ x, y");             }         }          private void touch_move(float x, float y) { // on finger  motion             float dx = math.abs(x - mx); // difference between x , x             float dy = math.abs(y - my);             if (dx >= touch_tolerance || dy >= touch_tolerance) { // if coordinates outside screen? if touching hard enough?                 mx = (int) (math.round(x));                 = (int) (math.round(y));                 if (addobjectmode == true) {                     myrect.set(ix, iy, mx, my);                 } else if (addappliancemode == true) { // whatever here gets repeated loads if move (e.g. per pixel)                     maketoast("user moved appliance");// dont set myrect                 }             }         }          @suppresswarnings("deprecation")         private void touch_up() { // on finger release             if (addobjectmode == true) {                 myrect.set(ix, iy, mx, my);                 mycanvas.drawrect(ix, iy, mx, my, mypaint);                 maketoast("touchup,  phone call dialogs!");                 dialogstarter();             } else if (addappliancemode == true) {                 //  phone call  add together appliance dialog                 maketoast("call appliance dialog");                 showdialog(dialog_appliance_classification);                 //mycanvas.drawbitmap(bmp, mx, my, mybitmappaint);             }         }

its drawing bitmap fails have code choses bmp draw based on user chose gets called in wrong order.

here dialog onclicklistener code:

.setpositivebutton("ok",                         new dialoginterface.onclicklistener() {                             public void onclick(dialoginterface dialog,                                     int whichbutton) {                                 maketoast("user clicked ok");                                 if (islamp == true) {                                     resources res = getresources();                                     bmp = bitmapfactory.decoderesource(res,                                             r.drawable.lamp);                                     // code draw lamp canvas here                                     homerview.drawapplianceicon();                                     maketoast("lamp drawn canvas");                                 }                             }                         })

there error @ drawapplianceicon() cannot phone call method contained in custom view class if seek homerview.drawapplianceicon().

it returns error: "cannot create static reference non-static method drawapplianceicon() type drawnewplans.homerview"

heres hierarchy:

public class drawnewplans extends activity implements colorpickerdialog.oncolorchangedlistener {     protected void oncreate(bundle savedinstancestate) { // on create method - initialises activity     protected dialog oncreatedialog(int id) { // dialog creator code     public void colorchanged(int color) { // implemented method when color changed     public class homerview extends view { // custom view drawing on         protected void ondraw(canvas canvas) { // method used when want draw our canvas         protected void onsizechanged(int w, int h, int oldw, int oldh) { // if screen size changes, alter bitmap size         private void touch_start(float x, float y) { // on finger touchdown         private void touch_move(float x, float y) { // on finger  motion         private void touch_up() { // on finger release         public boolean ontouchevent(motionevent event) { // on touch event         public void drawapplianceicon() { // code im working on     public boolean oncreateoptionsmenu(menu menu) { // on menu creation     public void dialogstarter() { // starts dialogs gathering user submitted  info     public void checkstoredobjects() { // checks stored in object list     public void resetvalues() { // resets values of object null, reuse     public boolean onprepareoptionsmenu(menu menu) { // method needed inflate menu     public boolean onoptionsitemselected(menuitem item) { // method containing code when menu item selected     public void maketoast(string message) { // method display pop short duration     public void makelongtoast(string message) { // method display pop long duration     public void redrawmode() { // reenables drawing mode resetting mypaint     public class getlocations extends asynctask<void, integer, jsonarray> { // asynctask class getting homer locations

edit: unfortunately reply accepted isn't calling piece of code want correctly! :(

here's revised code:

drawnewplans.this.myhomer.drawapplianceicon(200, 200); // should  phone call method contained in custom view draws bmp coordinates provided.

the method code:

public void drawapplianceicon(float x, float y) { mycanvas.drawbitmap(bmp, x-50, y-50, mybitmappaint); }

this works when called touch_start() in custom view class not when called via phone call in oncreatedialog method. sorry pain , have massive long question - there improve way of discussing this? sense starting new question mean have repeat context of programme on again.
