This is a poll of sorts about common concurrency problems in Java. An example might be the classic deadlock or race condition or perhaps EDT threading bugs in Swing. I'm interested both in a breadth of possible issues but also in what issues are most common. So, please leave one specific answer of a Java concurrency bug per comment an...
I have a bizarre rendering issue when I'm trying to use anti-aliased graphics in WPF. Here's a simplified version. If I use the following XAML <Window x:Class="RenderingBug.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Width="300" Heigh...
We have a MFC 8 application compiled with /CLR that contains a larger amount of Windows Forms UserControls wich again contain WPF user controls using ElementHost. Due to the architecture of our software we can not use HwndHost directly. We observed an extremely strange behavior here that we can not make any sense of: When the CPU load i...
I started using FogBugz as my project management tool. So I keep adding bugs and new features to it. The problem is FogBugz doesn't support subtasks for features, therefore I'm ending up adding all steps of implementing a feature as a text into the description box. But so far this is quite inefficient in many ways. It's not clear "what ...
What's going on?! Subtraction works fine until I get to 0.1 - 0.1. I'm in visual c# 2008 using the nonoba.com API. Console.WriteLine("hit! " + Users[targetNum].character.health + " : " + player.character.profile.attackPower); Users[targetNum].character.health -= player.character.profile.attackPower; Console.WriteLine("health! " + User...
I have been using dean edwards ie7/8 script. Not sure if it's my implementation or not but sometimes I would experience ie6 issues that weren't quite fixed or required special handling which meant I would be back where I started, caring about ie6. So, I was wondering if ie7/8 is still the go or if some other practice/solution was better....
I attempted to open a Java bug last Halloween. I immediately got a response that my submission was accepted, and have heard nothing since. Looking at Sun's web pages, I can't found any contact information where I can inquire. Almost two weeks ago I made a post in the Sun forums in what appears to be the most appropriate area and have ...
I have written some code that works pretty well, but I have a strange bug Here is an example... PLEASE WATCH MY COMBOBOX BUG VIDEO Like I said, this works well every time datachanged fires - the right index is selected and the displayField is displayed but, everytime after I type some text in the combobox, later, when the "datachan...
The Web browser's Window.External object is always null! To reproduce drop a web browser on a new winform and type: Option Strict Off Public Class Form1 Private Sub Form1_Load() Handles MyBase.LoadMe.WebBrowser1.Document.Window.DomWindow.External.AddFavorite("http://www.google.com") End Sub End Class Make certain you...
While investigating a reported problem with my site loading slowly, I came across an issue where I noticed (via firebug) that my flash file was loading twice. After a bit of investigation I tracked it down to a firefox bug combined with the usage of SWFObject 2.0. Now, I noticed on the thread that someone mentioned that you can workaro...
Hi Everbody, I am getting this error message while trying to access a wordpress blog which is installed in a directory. Is this due to .htaccess or something? Any help is appreciated. 'The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, webmas...
I was debugging some code in Visual Studio 2005, when I noticed that the IDE was not hitting breakpoints in a particular generic class. I could manually step into the class, but the tool-tips shown when hovering over references contained nothing but memory addresses instead of the normal friendly tool-tips. It turns out that the proble...
What was your most serious production bug? This could be any bug you contributed to the making of or solving in a live system. [moved my response to the answers] ...
Hi everybody, I just considered using the new TDictionary type. But On QualityCentral I read about two memory leaks caused by TDictionary: http://qc.codegear.com/wc/qcmain.aspx?d=67355 I just implemented the proposed workaround, basically subclassing TDictionary, overriding the destructor and manually freing the two objects that cause...
I read what-payment-structure-do-you-use-for-small-projects and I wonder how you guys are dealing with bug vs. feature. I once had a situation where a client wanted static reports. Then near the end of the project after most of the work on reports had been done he said he had always wanted dynamic reports. That change was not easy, beca...
There seems to be a bug with .Net winform's button. If you left click and hold it on a winform button, then right click (while holding down your left click), then release your right click, then drag your button to outside of the button, then release your left click, it seems that your button will be "stucked" - it won't back to depressed...
I would like my program to email me a bug-report when it fails. Is there any way of doing this... safely? I have found I can use System.Net.Mail MailMessage and SmtpClient and such, but of course, I will have to provide a username and a password to it (unless someone knows of one that doesn't need it?). And putting that in code I find a ...
When we upgraded MVC beta to MVC RC1 the development webserver that visual studio has suddenly crashed at some point in the application. After some searching I narrowed the bug to this simple line: if (!helper.ViewData.ContainsKey("SomeString")) SomeString is at that moment present in the viewData so the if statement should return fal...
The MSDN and Microsoft websites tout new features of Visual Studio. However, I am interested in finding a list of bugs fixed in the new release, if such a list exists. If no such official list exists, I am interested in blogs of Visual Studio developers and users of Visual Studio, reporting on the fixing of bugs in 2008 (release or SP1)...
Has anybody encountered this problem that DoCmd.OutputTo acOutputQuery deletes the query itself, the second time it is run? Is there any workaround/patch for this bug (at least seems like a bug to me)? Is there a better way to do this? ...
