• .NET Development How to intentionally do interop like this: Managed->CCW->RCW->Managed

  VS2005 prevents me from adding a reference to a type library that was exported from a .NET assembly. A message pops up that says "The ActiveX type library was exported from a .NET assembly and cannot be added as a reference, add a reference to the .NET assembly instead." The message makes perfect sense, because it would be foolish to take the performance hit of going through a COM interface when you could have just stuck with managed code. But my situation is different. It's my job to TEST the COM interface in a product that is written with managed code, and I need to use managed code to drive the testing. If I don't use the COM interface, then I'm not really testing it. So, after extensive effort, I still don't have a g ...Show All

• Visual Basic Firing new event in existing control?

  Hi, I'm new to Visual Basic 2005 (Express Edition) and I' decided to build my own PrintPreviewDialog using the PrintPreviewControl. One of the properties of the PrintPreviewControl is the Zoom Propertie. Unfortunately, the control doesn't provide a ZoomChanged event and I need to know when this propertie is modified (by the user, by the program or by resizing the control). Is there a way to trigger a ZoomChanged event everytime the value of the Zoom propertie change I created a new UserControl that inherit from the PrintPreviewControl but I'm not sure where to go from there. Hmm, that would change the Zoom property value without raising an event. Using Overloads instead of Shadows ensures tha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creators Club

  Quick question about membership in the Creators Club. I have 3 profiles registered on my Xbox 360. If I enroll my profile (GamerTag) in the Creators Club and upload a game will all rest of the local profiles be able to play the game as well All three profiles are Gold level profiles. Thanks, Mike Hi Mike, The solution is to have the other profiles sign in after you have run the XNA Game Launcher. That way you can play multiplayer games on the same machines. But the subscription holder must always be the one to log in first. Thanks! ...Show All

• Visual Studio Team System TFS Fills up disk?

  Not sure if anyone else has seen this issue. Didn't have a chance to reproduct, but I think TFS source control will dump at certain intervals if you have a deleted SID in one of your security groups that could be used. Our disk/temp directory kept getting filled, the event log mentioned something about an invalid id, I had to search through all the groups to find it and remove it. Anyone else seen this Seems like this is something where it should not dump just because of an old deleted SID. I looked I didn't see any reports unfortunately Any other place info would be kept Not able to repro there ...Show All
