Hi everybody,
I'm developping a web service application which access to several COM
objects contained in an EXE file. I've created Interop (using tlbimpl tool)
for all typelib.
In my webservice I can instanciate one of these COM object but when I call
one method of this object I get an InvalidCastExce ption that tells me that
the QueryInterface failed to retrieve the appropriate interface.
The same Interop is perfectly running in a Win32 application (not a web
service). Is there any configuration/patch of IIS / Windows 2000 to solve
this ?
I'm running on Windows 2000 and developing using VS .NET 2003.
Please help me !!!
