I’m currently developing what is more or less a script that needs to get some data from a VB 6 COM dll. This dll is currently used in a MS Word VBA project, and it exports classes, etc to the VBA code. It is added in the Tools -> References menu in the VBA editor, and I can see it’s classes in the object browser of VBA.

From my readings, it is possible to use a VB6 COM library in VB.NET (or at least, it is supposed to be able to.) As it should be possible in VB.NET, and since .NET runs on the CLR, and since IronPython does to, logically, can’t i access this ancient DLL from IronPython?

I have tried import clr; clr.AddReferenceToFileAndPath(dllpath) in IronPython, but keep getting ‘IOError: file does not exist’, which is clearly false.

If anyone can point me to using a VB6 COM object in /any/ .NET language, that would be greatly appreciated.

Thanks!

PS: No, I can’t edit / view source of the COM DLL, it’s 3rd party proprietary stuff.
PPS: Any way I can get the GUID / COM ‘name; of the dll?

    You need to generate a Runtime COM Wrapper assembly using the tlbimp tool, and add a reference to that; languages which support .net attributes can do the interoperation explicitly, but even there, autogenerating the wrapper is far simpler.

    Inspecting the wrapper assembly in ildasm will show exactly how the conversion has been performed.
