• MooTools Fx.Slide throwing this.element is null

  - by Brant

  The following code is throwing the error "this.element is null". However, the wid_cont is definitely grabbing an element. window.addEvent('domready',function(){ var min = $(document.body).getElements('a.widget_minimize'); min.addEvent('click', function(event){ event.stop(); //var box = ; var wid_cont = ($(this).getParents('.widget_box').getElement('.widget_box_content_cont')); var myVerticalSlide = new Fx.Slide(wid_cont); myVerticalSlide.slideOut(); } ); }); It's moo tools 1.2.4 and has the fx.slide included....

• Detecting a Key Press Squashed by Another Application

  - by Eric Smith

  I have a WPF application I'm planning to use as an overlay for a DirectX game (specifically Bad Company 2). I'm using WM_KEYBOARD_LL hook to detect KeyDown events so I can bring my app to the foreground when a specific button is pressed. This works perfectly except for when the game is running (I've also noticed this problem with Window's "Chess Titans" so it may be a DirectX thing). As far as I can work out, when the game detects a keyboard press, it "eats" the event and doesn't pass the CallNextHookEx() method like it should, which would allow the key press message to be moved along to the next application in the queue. I'm wondering if there's any sort of work-around to this? It seems kind of unfair that a single application can just willy-nilly eat up messages like that. Thanks! :) Relevant MSDN documentation: http://msdn.microsoft.com/en-us/library/ms644985%28VS.85%29.aspx

• Insert an ajaxified Webpart into an existing MOSS site

  - by mamoo

  Hi everybody, I need to code a webpart which purpose is to asynchronously fetch some documents and display them into an existing page. Unfortunately I have to face a lot of rescritcions and my struggle to find a solution seems useleess so far. 1) I cannot use Microsoft asp.net ajax 2) I must use Jsonp because the called service (page, whatever...) is outside the site's domain. That's not a big problem. 3) I have no possibility to alter the existing page code, so I cannot reference an external library such as JQuery. 4) For the same reason I have no possibility to call my methods on the window.onLoad event, so here the question is: how can I be sure that everything is correctly loaded before triggering my ajax call? 5) Since several instances of the same webpart can be placed into the same page, can there be some possible conflicts among the various js functions?

• Android draw using SurfaceView and Thread

  - by Morten Høgseth

  I am trying to draw a ball to my screen using 3 classes. I have read a little about this and I found a code snippet that works using the 3 classes on one page, Playing with graphics in Android I altered the code so that I have a ball that is moving and shifts direction when hitting the wall like the picture below (this is using the code in the link). Now I like to separate the classes into 3 different pages for not making everything so crowded, everything is set up the same way. Here are the 3 classes I have. BallActivity.java Ball.java BallThread.java package com.brick.breaker; import android.app.Activity; import android.os.Bundle; import android.view.Window; import android.view.WindowManager; public class BallActivity extends Activity { private Ball ball; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); ball = new Ball(this); setContentView(ball); } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); setContentView(null); ball = null; finish(); } } package com.brick.breaker; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android.view.SurfaceHolder; import android.view.SurfaceView; public class Ball extends SurfaceView implements SurfaceHolder.Callback { private BallThread ballThread = null; private Bitmap bitmap; private float x, y; private float vx, vy; public Ball(Context context) { super(context); // TODO Auto-generated constructor stub bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ball); x = 50.0f; y = 50.0f; vx = 10.0f; vy = 10.0f; getHolder().addCallback(this); ballThread = new BallThread(getHolder(), this); } protected void onDraw(Canvas canvas) { update(canvas); canvas.drawBitmap(bitmap, x, y, null); } public void update(Canvas canvas) { checkCollisions(canvas); x += vx; y += vy; } public void checkCollisions(Canvas canvas) { if(x - vx < 0) { vx = Math.abs(vx); } else if(x + vx > canvas.getWidth() - getBitmapWidth()) { vx = -Math.abs(vx); } if(y - vy < 0) { vy = Math.abs(vy); } else if(y + vy > canvas.getHeight() - getBitmapHeight()) { vy = -Math.abs(vy); } } public int getBitmapWidth() { if(bitmap != null) { return bitmap.getWidth(); } else { return 0; } } public int getBitmapHeight() { if(bitmap != null) { return bitmap.getHeight(); } else { return 0; } } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { // TODO Auto-generated method stub } public void surfaceCreated(SurfaceHolder holder) { // TODO Auto-generated method stub ballThread.setRunnable(true); ballThread.start(); } public void surfaceDestroyed(SurfaceHolder holder) { // TODO Auto-generated method stub boolean retry = true; ballThread.setRunnable(false); while(retry) { try { ballThread.join(); retry = false; } catch(InterruptedException ie) { //Try again and again and again } break; } ballThread = null; } } package com.brick.breaker; import android.graphics.Canvas; import android.view.SurfaceHolder; public class BallThread extends Thread { private SurfaceHolder sh; private Ball ball; private Canvas canvas; private boolean run = false; public BallThread(SurfaceHolder _holder,Ball _ball) { sh = _holder; ball = _ball; } public void setRunnable(boolean _run) { run = _run; } public void run() { while(run) { canvas = null; try { canvas = sh.lockCanvas(null); synchronized(sh) { ball.onDraw(canvas); } } finally { if(canvas != null) { sh.unlockCanvasAndPost(canvas); } } } } public Canvas getCanvas() { if(canvas != null) { return canvas; } else { return null; } } } Here is a picture that shows the outcome of these classes. I've tried to figure this out but since I am pretty new to Android development I thought I could ask for help. Does any one know what is causing the ball to be draw like that? The code is pretty much the same as the one in the link and I have tried to experiment to find a solution but no luck. Thx in advance for any help=)

• jquery noConflict not working in IE8 only

  - by slik

  I have a website using the prootype framework and I am looking to use a jquery plugin. Everything works just not in IE8. It works in ie7 which amazes me. Any idea what maybe wrong? jQuery.noConflict(); function OpenUp(sURL){ window.open(sURL,null,'height=560,width=820,status=yes,toolbar=yes,menubar=yes,location=yes,resizable=yes,scrollbars=yes',false); } jQuery(document).ready(function($) { $("head").append("<link>"); css = $("head").children(":last"); css.attr({ rel: "stylesheet", type: "text/css", href: "/my/docs/jquery.simplyscroll.css" }); $("#scroller").simplyScroll({ autoMode: 'loop', framerate: 1, speed: 1 }); }); I also tired the following: var $j = jQuery.noConflict(); var j = jQuery.noConflict(); everythig works just not in IE8 alone.

• Add Web Reference prompts for credentials with "Discovery Credential" dialog but won't accept valid

  - by Eden

  I'm attempting to add a web reference to my ASP.Net 3.0 project. This is a reference to the SQL Server Reporting Services web service. I have verified the service is up and running, but when I try to add the web reference in my project, I am prompted for my credentials, which I enter, and then prompted again and again and again. I have to hit cancel to stop the vicious cycle. When I do that the service definition comes up in the window, but the "Add Reference" button is disabled so I can't add the reference to my project. I have limited knowledge of SQL Reporting Services configurations. If anyone knows how to resolve this problem I'd really appreicate it.

• MooTools Classes and JsDoc

  - by Joel Alejandro

  I have the following Moo class: Nem.Ui.Window = new Class({ Implements: [Options, Events], options: { caption: "Ventana", icon: $empty, centered: true, id: $empty, width: $empty, height: $empty, modal: false, desktop: $empty, x: $empty, y: $empty, layout: $empty }, initialize: function(options) { this.setOptions(options); /* ... */ }, setHtmlContents: function(content) { /* ... */ }, setText: function(text) { /* ... */ }, close: function(win) { /* ... */ }, /* ... */ }); I want to document it with JsDoc. I read you can use @lends [class].prototype inside new Class and mark initialize with the @constructs tag. How can I mark methods and events such? I.E.: setHtmlContents should be a method, close should be an event. Also, can the elements under options be documented, somehow?

• Jaxer and HTTP proxy requests...

  - by rakhavan

  Thanks to everyone in advance. I'm using Jaxer.sandbox and making requests just fine. I'd like these requests to go through my http proxy (like squid for example). Here is the code I that is currently working for me. window.onload = function() { //the url to scrape var url = "http://www.cnn.com/"; //our sandboxed browser var sandbox = new Jaxer.Sandbox(); //open optons var openOptions = new Jaxer.Sandbox.OpenOptions(); openOptions.allowJavaScript = false; openOptions.allowMetaRedirects = false; openOptions.allowSubFrames = false; openOptions.allowSubFrames = false; openOptions.onload = function() { //do something onload }; //make the call sandbox.open(url, null, openOptions); //write the response Jaxer.response.setContents(sandbox.toHTML()); }; How can I send this request through a proxy server? Thanks, Reza.

• Is it possible to implement a GC.GetAliveInstancesOf<T>() (for use in debugging)?

  - by Omer Raviv

  Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific base class. I'll emphasize that I only want to use this method during debugging, so I don't care that the GC may change an object's address in memory during runtime. One idea might be to somehow harness the !dumpheap –type command of SOS, and do some magic trick to create a temporary variable and have it point out to the memory address printed by SOS. Does anyone have a solution that works?

• How to troubleshoot dependencies not copying.

  - by AngryHacker

  I have an EXE project A, which references a class library project B (all in the same solution). Project B has a reference to about 10 3rd party DLLs (from DevExpress). All the referenced assemblies have Copy Local set to true. When I build the entire solution, the resulting DLL from project B is copied into the bin/debug of project A. However, none of the dependencies of project B get copied. I looked in the Output window during compile and all looks good. There aren't any errors. How do I troubleshoot this?

• [C#] Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

  - by Luke Mcneice

  Hi all, I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?

• jQuery iframe overlay with flash closing issue

  - by Ryan Max

  Hello, I have a site that has a jQuery overlay, which contains an iframe, which pulls in another site that has flash in it. One of the buttons in the flash has editable parameters in xml, and I can change where the link points to. I want this button to close the overlay, but I can't quite figure out how to get it to work. I have tried the following: closeSection(); and parent.closeSection(); and window.parent.closeSection(); None of which work. Though the last two come close. They seem to close the flash, as the iframe just goes blank. Can anyone steer me in the right direction?

• reload an iFrame with the scrollbar set to a specific coordinate.

  - by Luis Armando

  I was wondering how could I reload any website using javascript and set it in a way that when it reloads the scrollbar is looking scrolled down to a certain position. I'm unsure as to how to look for this in Google honestly so I haven't digged up much =/. I think it has to be somewhere in the instruction to reload it and so far I have: document.getElementById('life').contentWindow.scroll(0,0); //doesn't work document.getElementById('life').contentWindow.location.reload(); although the first one gets me: Permission denied to get property Window.scroll of http://www.google.com.

• Dynamic size canvas with Scroll bars

  - by Pawan

  Hi, I am developing a simple WPF application without any auto layout. The goal is when a user clicks (mouse down) a element (say textBlock) will appear at the location of the mouse click. For this I am using canvas panel embedded in a Grid of 1 row, 1 column and scrollviewer (visible). The issues are: 1. when the application window is resized the scroll viewers do not become active. 2. I want the ability to auto grow the canvas with mouse drag. Something like in MS-Excel when user drags the mouse horizontally/vertically the canvas should grow. I have searched net a lot to figure this out and am unable to get an answer. Any help in this regard would be great. Thanks a bunch in advance. -P

• Understanding addSubview: memoryLeak

  - by Leandros

  I don't really understand, why this code leaks. ParentViewController *parentController = [[ParentViewController alloc] init]; ChildViewController *childController = [[ChildViewController alloc] init]; [parentController containerAddChildViewController:childController]; [[self window] setRootViewController:parentController]; - (void)containerAddChildViewController:(UIViewController *)childViewController { [self addChildViewController:childViewController]; [self.view addSubview:childViewController.view]; // Instruments is telling me, the leak occurs here! [childViewController didMoveToParentViewController:self]; } According to Instruments, this line: [self.view addSubview:childViewController.view]; is leaking. The whole code is called once in application:didFinishLaunchingWithOptions:, but it is shown that this code is responsible for 30 leaks (approx. 1.12 kB).

• Silverlight 4 Out-of-browser application into the browser ?

  - by Niklaos

  Hi guys, I just lost 5 hours looking for a answer which i haven't been able to find :p First, I'd like to force a trusted application (i need to access the file system) to display into the browser. Based on what i found on google a trusted application must be installed and launched as a desktop application (also called out-of-browser application). So, i want to have an installed application on the client side but meanwhile, the user must also be able to start this same application into a browser window when he goes on my web site. Is this possible ? Second, I'd like to give to the user the possibility to start the application from the browser. To be clear be the application is installed on the client computer but i want a button on my web site which starts the desktop application. How can i do that ? Thanks

• Ampersand in GET, PHP

  - by NightMICU

  I have a simple form that generates a new photo gallery, sending the title and a description to MySQL and redirecting the user to a page where they can upload photos. Everything worked fine until the ampersand entered the equation. The information is sent from a jQuery modal dialog to a PHP page which then submits the entry to the database. After Ajax completes successfully, the user is sent to the upload page with a GET URL to tell the page what album it is uploading to -- $.ajax ({ type: "POST", url: "../../includes/forms/add_gallery.php", data: $("#addGallery form").serialize(), success: function() { $("#addGallery").dialog('close'); window.location.href = 'display_album.php?album=' + title; } }); If the title has an ampersand, the Title field on the upload page does not display properly. Is there a way to escape ampersand for GET? Thanks

• Possible memory leak problem

  I write two pieces of c programs like following, during memcheck process using Valgrind, a lot of mem leak information is given. int GetMemory(int framewidth, int frameheight, int SR/*, int blocksize*//*,int ALL_REF_NUM*/) { //int i,j; int memory_size = 0; //int refnum = ALL_REF_NUM; int input_search_range = SR; memory_size += get_mem2D(&curFrameY, frameheight, framewidth); memory_size += get_mem2D(&curFrameU, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&curFrameV, frameheight>>1, framewidth>>1); memory_size += get_mem3D(&prevFrameY, refnum, frameheight, framewidth);// to allocate reference frame buffer accoding to the reference frame number memory_size += get_mem3D(&prevFrameU, refnum, frameheight>>1, framewidth>>1); memory_size += get_mem3D(&prevFrameV, refnum, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&mpFrameY, frameheight, framewidth); memory_size += get_mem2D(&mpFrameU, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&mpFrameV, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&searchwindow, input_search_range*2 + blocksize, input_search_range*2 + blocksize);// to allocate search window according to the searchrange /*memory_size +=*/ get_mem1D(/*&SAD_cost, height, width*/); // memory_size += get_mem2D(&searchwindow, 80, 80);// if searchrange is 32, then only 32+1+32+15 pixels is needed in each row and col, therefore the range of // search window is enough to be set to 80 ! memory_size += get_mem2Dint(&all_mv, height/blocksize, width/blocksize); return 0; } void FreeMemory(int refno) { free_mem2D(curFrameY); free_mem2D(curFrameU); free_mem2D(curFrameV); free_mem3D(prevFrameY,refno); free_mem3D(prevFrameU,refno); free_mem3D(prevFrameV,refno); free_mem2D(mpFrameY); free_mem2D(mpFrameU); free_mem2D(mpFrameV); free_mem2D(searchwindow); free_mem1D(); free_mem2Dint(all_mv); } void free_mem1D() { free(SAD_cost); } Now I hope to make sure where are the possible problems in my program? Here I may post some valgrind information to let you know about the actual error information. ==29105== by 0x804A906: main (me_search.c:1480) ==29105== ==29105== ==29105== HEAP SUMMARY: ==29105== in use at exit: 124,088 bytes in 18 blocks ==29105== total heap usage: 37 allocs, 21 frees, 749,276 bytes allocated ==29105== ==29105== 272 bytes in 1 blocks are still reachable in loss record 1 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804885E: GetMemory (me_search.c:117) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 352 bytes in 1 blocks are still reachable in loss record 2 of 18 ==29105== at 0x4024F20: malloc (vg_replace_malloc.c:236) ==29105== by 0x409537E: __fopen_internal (iofopen.c:76) ==29105== by 0x409544B: fopen@@GLIBC_2.1 (iofopen.c:107) ==29105== by 0x804A660: main (me_search.c:1439) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 3 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048724: GetMemory (me_search.c:106) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 4 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048747: GetMemory (me_search.c:107) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 5 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048809: GetMemory (me_search.c:114) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 6 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804882C: GetMemory (me_search.c:115) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are definitely lost in loss record 7 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804A4F8: get_mem3D (me_search.c:1393) ==29105== by 0x804879B: GetMemory (me_search.c:110) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are definitely lost in loss record 8 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804A4F8: get_mem3D (me_search.c:1393) ==29105== by 0x80487C9: GetMemory (me_search.c:111) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 1,168 bytes in 1 blocks are still reachable in loss record 9 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048701: GetMemory (me_search.c:105) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 1,168 bytes in 1 blocks are still reachable in loss record 10 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x80487E6: GetMemory (me_search.c:113) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 1,168 bytes in 1 blocks are definitely lost in loss record 11 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804A4F8: get_mem3D (me_search.c:1393) ==29105== by 0x804876D: GetMemory (me_search.c:109) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 6,336 bytes in 1 blocks are definitely lost in loss record 12 of 18 ==29105== at 0x4024F20: malloc (vg_replace_malloc.c:236) ==29105== by 0x804A25C: get_mem1D (me_search.c:1295) ==29105== by 0x8048866: GetMemory (me_search.c:119) ==29105== by 0x804A757: main (me_search.c:1456)

• Can we run windowservice or EXE in Azure website or in Virtual Machine?

  - by Arun Rana

  I have experienced with cloud service/hosted service on Azure. However regarding another project i am confused in selection in terms of functionalities. I have project (2 tier asp.net app) with that i need to run windowservice or exe which will do some functionality every day (like fetch data) so my confusions are as below Regarding Azure website Can i access RDP if i'll move to reserved instance? can i run windowservice/exe ? Regarding Virtual Machine Is it same as dedicated server? can i use WASD as database from application reside in same? I think i can run any exe and installed anything however azure is going to recycle this and if yes then what happened on recycling? can i use new window server 2012 (VHD) in that? Azure website & VM both are in preview mode so is it reliable to use it as production version?

• Qt Graphics Scene mouse event propagation

  - by Olorin

  hello i'm learning qt and i'm doing the folowing to add some widgets to a graphics scene void MainWindow::addWidgets(QList<QWidget *> &list, int code) { if(code == CODE_INFO) { QWidget *layoutWidget = new QWidget(); QVBoxLayout *layout = new QVBoxLayout(); foreach(QWidget *w, list) { layout->addWidget(w); this->connect(((ProductInfo*)w), SIGNAL(productClicked()), this, SLOT(getProductDetails())); } layoutWidget->setLayout(layout); this->scene->addWidget(layoutWidget); } } my ProductInfo class processes mouse release and emits a signal void ProductInfo::mouseReleaseEvent(QMouseEvent *e) { QWidget::mouseReleaseEvent(e); emit productClicked(); } the problem is after adding the widgets to the scene they no longer get the mouse release event and don't emit productClicked signal but if i add them to the main window(not to the scene) they work as expected. What am i doing wrong?

• Interface Builder and Xcode integration not working

  - by Martin Cote

  After having installed the iPhone SDK 3.1.2, Interface Builder is not in sync with Xcode anymore. The light indicator at the bottom of the XIB window is grey. IB doesn't see any files from the Xcode project. Xcode is always open when I start IB. I tried rebooting. No luck. I tried removing the preferences files for Xcode/IB. No luck. I tried reinstalling Xcode/IB. Still no luck. This page explains how IB monitors the changes in Xcode. While it was an interesting read, it didn't provide any help about how to investigate my problem. Any help would be appreciated. EDIT Here's additional information. I enabled the debug logs for launchd, and I noticed the following line that appears every time Interface Builder is started: [0x0-0x1b01b].com.apple.InterfaceBuilder3[315]: Couldn't open shared capabilities memory GSCapabilities (No such file or directory) This really seems to be related to my issue.
