Does anyone know how to debug an InprocServer32 COM object written in c++ (ATL using VC50) called from an ASP.  My ASP is using the CreateObject(myComClass.myComObject) function to invoke it.  I know how to debug an InProcServer called from a VB app, another dll, or an exe.  However, I don't know what to attach to or what executable to use for this debug session.  
I'm running NT server 4.0 with IIS.  I'm also using MTS but have have it disabled for now.

The easiest way is to load your workspace for your COM project. Set your breakpoints wherever you want them. Then select the Build | Start Debug | Attach To Process. Make sure Show System Process is checked. Then select inetinfo and press OK. This will cause the debugger to watch those breakpoints.

thui, thanks for the answer.  Actually, I tried that today.  At least I think I did.  I tried so many things, I'm so confused!  I'm going to try this again tomorrow and I'll let you know what happened.

Thanks, Sam

thui, you were right!  Your solution was a success.  There were two issues that I came across however.

1) I had to actually run a query using ASP before starting my debugging session.  This loads some additional vbscript and ASP Dll's that are needed.  

2) inetinfo gets unloaded after each session. Consequenly, I have to restart the computer after each session.  I tried manually executing inetinfo after my debugging session but it nly stayed running for a few seconds.

Have you experienced these conditions?
