• Visual Studio Team System TFS Not Ready for Prime time...not even close...

  I hate to say this but TFS has to be the worst application install I have ever seen. The documentation is lacking and the entire thing feels like a kludge. I cannot imagine this being ready any time soon. Many of the same bugs I saw in previous versions are still there. Just bad. After 7 reinstall attempts (because of many different reasons...one of which was that the TFS accounts ALL need to currently be admins or it wont work!) I finally got it to work. But only when I went with an ActiveDirectory structure would it work. No way would it work properly in a work group. Now after slaving to get it working, I find that it has bad performance ...Show All

• Visual C# Socket question.

  When I close a socket in the server side, I found the client will receive some empty data automatically, even though I haven't sent anything in my code. I also found that some empty data will also be sent to the server automatically if I close a client side socket. These two cases could be reasonable since there may be some acknowledgement to be sent arround. Upon closing a server side socket by calling its Close(), it's wired to see that ReceiveDataFromClientCallBack() will be called id the socket is a work socket. And the AcceptClientCallBack() will be also be called if the socket is a listner socket. Anybody can explain this T ...Show All

  I am using VB Express to create an application and am pulling my hair out trying to get the cd to autorun. Using Project->Properties->Publish and then Options...

• Visual C# Calling a instanced method from static method

• Visual Studio 2008 (Pre-release) Multiple threads, UI, and images

  I'm currently trying to write an application that dynamically loads images in a background process in order to eventually display them on the UI. Essentially, my background thread creates objects that inherit from System.Windows.Media.Brush or System.Windows.Media.Drawing so that my UI can redraw itself using these objects. When running my code, I receive an InvalidOperationException with the explanation of " The calling thread may not access this object because the object is owned by a different thread. ". This appears to be behavior for any class that derives from System.Windows.Threading.DispatcherObject. My question is, how can ...Show All
