• Visual Studio Team System Source control and Sharepoint Integration

  Please tell me that you are going to fix this before the official release!! I am using VB not C++.  I really shouldn't have to care that my code is not running in the same thread as the one that created the form that contains the control that I am trying to update. Please fix this or at least have some real examples that show how to update a control on a form.  The examples that I found were not helpful at all. or, you could just set ystem.Windows.Forms. Control .CheckForIllegalCrossThreadCalls = false and all your cross threading problems go away. ...Show All
