.NET Development Collection Items Disappearing
So I have run into a serious problem that did not exist when I left work last week. I have items that are dissappearing from a collection as I iterate through it. I have a class called host which has a List<String> in it which has a list of Urls. There is only one way to get and remove urls, a property called NextUrl. public string NextUrl { get { string url; lock (_urls) { url = _urls[0]; _urls.RemoveAt(0); _lastTouched = DateTime.Now; } return url; } The loop is as follows foreach (Host h in currentList) { if (h.Count > 0) { DownloadUrlAsync(h.NextUrl); } } currentList is a contains a List of hosts.

Visual C# SQL fails to be recognized by Visual C# Express 2005
I recently installed Beta 2 of VCSE and also the SQL Server Express Edition, and after being unable to complete some tasks I required that SQL Express couldn't handle, I decided to uninstall it, and install my copy of SQL Server 2000 Dev on the machine instead. Now, VCSE fails to recognize the SQL Server that I installed, and when using the "Add New Connection" Wizard, I am unable to connect to the correct server. If I click on Advanced, the DataSource field is set to .\SQLExpress, and I am unable to change it. Is there some way to correct this issue Any help would be greatly appreciated. Thanks ^_^ Hi all, ...Show All

Visual Studio Express Editions VB app memory usage
I noticed that my VBE apps were consuming a lot of memory so I wrote a test app that consists of nothing more than a form with a single button. When I run the compiled .exe file, Windows Task Manager reports the the process is using over 8 meg of memory. If I minimize the app, memory usage drops to 372K. If I un-minimize the app, memory usage then jumps to approximately 2 meg & stays there with each successive minimize/un-minimize. Can somebody explain to me what is going on here Why does it initially have such a high memory usage for such a small app And why does it settle at 2 meg after minimizing once Thanks... ...Show All
Visual Studio 2008 (Pre-release) Peer Channel performance
Hi all! I am building a p2p application using WCF and the peer channel and one of the requisites of this application is to be able to send the higher number of updates per second. While doing some profiling, I noticed that server was sending (at least the sending method executed and returned) at the rate I had specified but clients were receiving at a variable rate. For instance, I specified an update rate of 170 miliseconds on the server and logs said it was sending more or less at that rate. But the logs on the client side were different: they showed a quite variable receiving rate (i.e. 171, 12, 189, 12, 231, 11, 171, 12, 232, ...Show All

Windows Forms 'PostMessage' in c#
Is there an equivalent to the win32's PostMessge() func in windows forms How do I create a user-defined message What I want to do is use my Form's message pump (I'm assuming there is one underneath), to synchronize events posted by seperate threads.

Visual C++ Strange error with _fileno
We're in the process of converting from visual studio 98 to 2005 (yes, we were a bit behind the times). Most of the changes are now dealt with, but there's one weird one that we can't figure out - it looks like a bug in the compiler. Here's the error we get: v:\frame\utils\.\preftext.c(104) : warning C4996: '_fileno' was declared deprecated C:\MSDev05\VC\include\stdio.h(219) : see declaration of '_fileno' Message: 'The POSIX name for this item is deprecated.
