• How to run unittest under pydev for Django?

  - by photon

  I configured properties for my django project under pydev. I can run the django app under pydev or under console window. I can also run unittest for app under console window. But I have problems to run unittest under pydev. I guess it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem?

• UDK ParticleSystem Problem

  - by EmAdpres

  I use below code to create my particles ( in fact, I don't know any other way.) spawnedParticleComponents = WorldInfo.MyEmitterPool.SpawnEmitter(ParticleSystem'ParticleName', Location, Rotator ); spawnedParticleComponents.setTranslation(newLocation); ... And unfortunately, I spawn many particles in game. When I play my game, after some time, I see Exceeded max active pooled emitters! Warning in console . To solve the problem, first, I tried spawnedParticleComponents.DeactivateSystem();, But it doesn't help. Then I try WorldInfo.MyEmitterPool.ClearPoolComponents(false);, But it doesn't either . :( How can I destroy many spawned particles and avoid this warning ?

• Avoiding display of Visual Studio Debugger when starting a new process from within java.exe

  - by Matt Sheppard

  How can I, from within a java program on windows, prevent a debugger window being displayed if a program I invoke crashes, and how can I detect the fact that it has crashed? Background I have a problem with a java application running on Windows which is launching an unreliable third party program by way of ProcessBuilder.start(). Specifically, if the external program crashes, the 'Visual Studio Just-In-time Debugger' window pops up asking if the user wants to debug the program. From the java application side, I'm happy to deal with the fact that under some circumstances, the third party program will crash, but I'd like to be able to detect and silently handle that situation from within the Java code without requiring any user interaction.

  - by Reini

  I'm trying to fetch some Data of a Oracle 10 Database. Some cells are containing german umlauts (äöü).

• Shift+Tab not working in TreeView control

  - by Christian

  I cannot get backwards navigation using Shift+Tab to work in a TreeView that contains TextBoxs, forward navigation using Tab works fine and jump from TextBox to TextBox inside the TreeView. Anytime Shift+Tab is used when one of the TextBoxes inside the TreeView, then the focus is move to the previous control outside the TreeView, instead of the previous control inside the TreeView. Also its only Shift+Tab navigation that are not working correctly, Ctrl+Shift+Tab work as expected and in the correct order. Any suggestions to what I'm doing wrong? Example code: <Window x:Class="TestTabTreeView.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <Style TargetType="TreeViewItem"> <Setter Property="KeyboardNavigation.TabNavigation" Value="Continue" /> </Style> </Window.Resources> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBox Text="First Line" Grid.Row="0" /> <TreeView Grid.Row="1" KeyboardNavigation.TabNavigation="Continue" IsTabStop="False"> <TreeViewItem IsExpanded="True"><TreeViewItem.Header><TextBox Text="Popular Words"/></TreeViewItem.Header> <TreeViewItem><TreeViewItem.Header><TextBox Text="Foo"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Bar"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Hello"/></TreeViewItem.Header></TreeViewItem> </TreeViewItem> <TreeViewItem IsExpanded="True"><TreeViewItem.Header><TextBox Text="Unpopular Words"/></TreeViewItem.Header> <TreeViewItem><TreeViewItem.Header><TextBox Text="Work"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Duplication"/></TreeViewItem.Header></TreeViewItem> </TreeViewItem> </TreeView> <TextBox Text="Last Line" Grid.Row="2" /> </Grid>

• This 24 Hours of PASS was "Different"

  - by RickHeiges

  Last week, the latest iteration of "24 Hours of PASS" was held. It was "Different" for me. Why? Because I was not an active participant on the days of the event other than being an attendee. I was involved in some aspects of the planning for the event when deciding the theme and format, etc. I was on many calls and email threads for the planning of this event. I did the moderator/speaker training a few weeks prior to the event. But on the days that the event was actually held, I was not on pins and...(read more)

• Android/Java AI agent framework/middleware

  - by corneliu

  I am looking for an AI agent framework to use as a starting point in an Android game I have to create for a university research project. It has been suggested to me to use JADE, but, as far as I can tell, it's not a suitable framework for games (at least for my game idea) because it runs in a split-execution mode, and it needs an always-active network connection to a main host. What I want is just a little something to give me a headstart. I am willing to adjust the game's features to the framework because it's more of a mockup game, and the purpose is to compare the performance of a couple of agents in the game world. The game will be very simplistic, with a minimal UI that displays various stats about the characters in the game (so no graphics, no pathfinding). Thank you.

• Use SendMessage in C# to perform a CTRL-C operation on a given handle

  - by gtaborga

  Hello everyone, I'm trying to perform a (CTRL-C) copy on a window. I've already managed to do this using SendInput but unfortunately that could fail if the window doesn't have focus. I'm trying to perform the same (CTRL-C) operation using SendMessage in C#. So far I haven't been successful in getting the WPARAM and LPARAM combination for this to work. I have also tried using SendMessage with the WM_COPY message but that didn't work for my needs. Please if anyone has done this before successfully using SendMessage I would greatly appreciate your help.

• Enforce VPN connection to access the Internet

  - by ch0wn

  I'm using a VPN when I'm online at an unencrypted wifi. Unfortunately, at my university the connection is quite unstable and at every reconnect the VPN connection is terminated and I manually need to reconnect to it using the NetworkManager, which obviously only works if I notice the reconnect. I enabled the option to automatically connect to the VPN in the NM options, but it seems to have no effect. Is there a way to enforce an active VPN connection before any other application can access the network connection so I can be sure not to send private data over unencrypted connections? Cheers, Pascal

  - by mp

  Hi, i have a simple css example, and i can't understand the behavior of one of my divs, when the horizontal scroll is displayed. so...when my browser window needs to display the horizontal scroll(when the window width is less than my div "content" width(1024px)), my div "footer" (that have the same "content's" parent and 100% width), seems to get an "extra blank space" on the right side. this space grows when I reduce the width of the window. any ideas about how can i get it off, or why it happens??thanks! heres my code: css: <style type="text/css"> html, body { height: 100%; width:100%; font-family:"Arial Black", Gadget, sans-serif; font-size:11px; font-variant:normal; } * { margin: 0; } .wrapper { min-height: 100%; height: auto !important; height: 100%; margin: 0 auto -4em; } #content{ width:1024px; margin:0px auto; background-color:#990; height:780px; } .footer, .push { height: 4em; width:100%; } #footer-content{ height:10px; background-color:#09F; width:100%; } </style> html: <body> <div class="wrapper"> <div id="content"> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.

• Xsl mime type problem

  - by savruk

  Hi, I have a busybox with lighttpd running on as http server. My problem is while firefox and opera can get the page with applied xsl, Arora(webkit) can not. Here is the script I use to get it work: <html> <head> <script> function loadXMLDoc(dname) { if (window.XMLHttpRequest) { xhttp=new XMLHttpRequest(); } else { xhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xhttp.open("GET",dname,false); xhttp.send(""); return xhttp.responseXML; } function querySt(ji) { hu = window.location.search.substring(1); gy = hu.split("&"); for (i=0;i<gy.length;i++) { ft = gy[i].split("="); if (ft[0] == ji) { return ft[1]; } } } function displayResult() { xml=loadXMLDoc("sample.xml"); alert(xml)//Gives [object Document] $scan=querySt("scan"); $sub = querySt("sub"); xsl=loadXMLDoc("sample.xsl"); alert(xsl)//Gives Null // code for IE if (window.ActiveXObject) { ex=xml.transformNode(xsl); document.getElementById("example").innerHTML=ex; } // code for Mozilla, Firefox, Opera, etc. else if (document.implementation && document.implementation.createDocument) { xsltProcessor=new XSLTProcessor(); xsltProcessor.importStylesheet(xsl); xsltProcessor.setParameter(null,"scan",$scan) if($sub != ""){ xsltProcessor.setParameter(null,"sub",$sub) } resultDocument = xsltProcessor.transformToFragment(xml,document); document.getElementById("example").appendChild(resultDocument); } } </script> </head> <body onload="displayResult()"> <div id="example" ></div> </body> </html> I tried to see if it load xsl well and put an alert(xsl) but it gives null. Other browser can get xml and xsl files perfectly. What can be the problem? Thanks P.S: It runs well on my local server with all browser.

• AppDelegate viewController memory leak?

  - by fuzzygoat

  I am just curious with regards to the correct way to create a view controller programatically. When I compile this code with the static analyser I get a leak (as you would expect) from the alloc. Should I just leave it as it needs to stay until the app exits anyways, or is there a cleaner way? - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSLog(@"UIApplication application:"); RectViewController *myController = [[RectViewController alloc] init]; [window addSubview:[myController view]]; [window makeKeyAndVisible]; return YES; } cheers Gary

• Ctrl+Click / Command+Click not working with analytics

  - by user347998

  Hi All, I created my own analytics for my site to track outbound click events using jquery. Now the thing with preventDefault() is that it does not allow for the Ctrl+Click or COmmand+click operation in the browser to open the link in new tab/window. So my solution was to detect e.metaKey || e.ctrlKey and use window.open. This does not work very great with safari unless the user changes browser behavior. I am wondering if anyone here knows what other analytics users do - like how does google etc deal with this problem in tracking outbound links? From this link: http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55527 - looks like google will also face the same problem. Thoughts?

• How do you use vim's quickfix feature?

  - by hora

  I'm a pretty new Vim user and I've found that its learning curve is quite steep (at least for me). I just installed this vim script for JavaScriptLint error checking, which shows errors in vim's quickfix window once I save a buffer. However, I don't know what to do next.. How do I 'scroll' through all the errors? How do I close the quickfix 'window'? How do I get it to check for errors after I've made changes to my code? I've looked at the vim quickfix docs but the amount of commands are overwhelming and I can't seem to find what I want. Any help would be appreciated. A side question: is there any way to have javascriptlint check for js errors for code residing in a .html file? Thanks!

• Component must be a valid peer (when i remove frame.add(Component);)

• Mixed alignment with Java Swing's GroupLayout

  - by zigdon

  I'm trying to build a GUI window in my application. What I'm trying to do is have a window, with a few buttons at the top, and a large text area. Something like this: +--------------------------------------------------+ | [button1] [button2] [button3] | | +----------------------------------------------+ | | | text area | | | | | | | | | | | | | | | +----------------------------------------------+ | +--------------------------------------------------+ I'm almost there, using GroupLayout: layout.setHorizontalGroup( layout.createParallelGroup() .addGroup(layout.createSequentialGroup() .addComponent(button1) .addComponent(button2)) .addComponent(closeWindow)) .addComponent(textarea1) ); layout.setVerticalGroup( layout.createSequentialGroup() .addGroup(layout.createParallelGroup() .addComponent(button1) .addComponent(button2) .addComponent(button3)) .addComponent(textarea) ); The problem is that this ends up with button3 aligned to the left, with the other two. I can't seem to figure out how I can specify the alignment on just that one button. I can do GroupLayout.Alignment.TRAILING on the entire button bar, but that hits all 3 buttons, which is also not quite right. So what's the correct approach? Since the alignment only applies for Parallel Groups, I don't think having a HorizontalGroup with two Sequential Groups in it will help? What am I missing?

• Show a taskbar item with a NativeWindow

  - by David Brown

  My application is intended to work almost entirely through a Windows 7 taskbar item with the use of thumbnails and jump lists. I know I can easily create a Form and simply hide it, but this seems like overkill. Plus, I'd like to toy around with NativeWindow as much as possible, because I've never used it before. Essentially, I have a class called RootWindow that derives from NativeWindow. I don't need a visible window at all, but simply something to process window messages and provide a taskbar item that I can attach thumbnails and jump lists to. Is there some kind of special CreateParams option I need to pass to CreateHandle? Or am I out of luck?

• Google Chrome + Ajax

  - by teehoo

  Im writing an ajax web app that uses Comet/Long Polling to keep the webpage up to date, and I noticed in Chrome, it treats the page as if its always loading (icon for the tab keeps spinning). I thought this was normal for Google Chrome + Ajax because even Google Wave had this behaviour. Well today I noticed that Google Wave no longer keeps the loading icon spinning, anyone know how they fixed this? Here's my ajax call code var xmlHttpReq = false; // Mozilla/Safari if (window.XMLHttpRequest) { xmlHttpReq = new XMLHttpRequest(); } // IE else if (window.ActiveXObject) { xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP"); } xmlHttpReq.open('GET', myURL, true); xmlHttpReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlHttpReq.onreadystatechange = function() { if (xmlHttpReq.readyState == 4) { updatePage(xmlHttpReq.responseText); } } xmlHttpReq.send(null);

• ScrollTo - toggle between min-height/fixed height

  - by Skoder

  Hi everyone, I'm trying to use the ScrollTo plugin, but I can't seem to get it working properly. I tried to view the source at the site I linked to but I'm trying to achieve something slightly different. I would like the window pane to change size according to the content (so the height would increase for longer text and would decrease for shorter text). However, when I supply a min-height (as opposed to a fixed height), the pane automatically changes to the maximum height when the page is loaded. So if I have something set to margin-top:1000px;, the pane will be 1000px in size regardless of what tab is currently displaying. The fix would be to use height instead, but that would mean that the window won't expand in height and the user would have to scroll. I got my code from viewing the source on the ScrollTo page, but I also tried this tutorial code. Thanks for any help
