• .NET Development Object does not match target type when raising an event from c# to VB6

  I have a c# .net DLL that I use from a VB6 app. It exposes an event, and the VB6 app is sinking it. The VB6 app is receiving the event, as long as it is raised from the main thread of the .net DLL. I have an aync task being handled inside the DLL (delegate BeginInvoke). Any attempt to raise the event from within that thread casuses the reported error, even from within the AsyncCallback function, when the thread is ending. I noticed that the delegate for the event is not declared inside the interface. It's in that module, but above the interface definition:     [ComVisible(false)]     public delegate void Logging ...Show All

• Visual Studio SourceSafe, VS.NET 2003 and Stored Procedure Versioning

  Hi, Any Help I am version controlling my stored procedures via .NET IDE & VSS. Background: ================== I have VS .NET 2003, Visual SourceSafe v6.0d and MS SQL Server 2000. When one wants to version control their stored procedures, they can do this fairly easily through the VS.NET IDE. As an FYI - If you care - Here is an old sample of how to do this http://weblogs.asp.net/fmarguerie/archive/2003/02/24/2880.aspx ================== Problem: The VSS database has MOVED (in this case, to a different server). Everything involving the SP versioning is now haywire. The problem seems to be rooted in the fact t ...Show All

Now 95% of the time the RPC Complete: that exec's a sp and the SP Complete: events in the trace duration times are almost identical. Somtimes i find the following situation.

• Visual Studio Team System Installing TFS on a SharePoint Portal Server 2003

  Heya, I'd like to install TFS on a SharePoint Portal Server 2003. Is this possible at all Do I still need to install Windows SharePoint Services Cheers, Chris Hi, Sharepoint portal server installs Windows Sharepoint Services by default. So you don't have to install it again. But TFS requires wss SP2 to be installed. So you will have to install WSS SP2 before starting the TFS installation.
