Inproc Server with Shared DLL

Environment: VC++ 4.1 / Win NT 4.0 From MSDN 

I have an inproc server that works nicely when it is statically
linked to MFC.  When I build it to use the MFC shared DLL it 
immediately crashes when my VB 4.0 client tries to attach to it:

	Dim MyInProc As Object
	Set MyInProc = CreateObject("Inproc")

Here's the error:

	Run-time error -2147221231 (80040111)

	OLE Automation error
	Class Factory cannot supply requested class

Any suggestions?

Thanks,

Chris Shafer

The reason is that MFC shared DLL works with applications written based 
on MFC only. Here the application is the main EXE but not the DLL. So if 
your application is written in VB, your DLL has to use static linked the MFC.
