I've implemented a simple .NET component exposed to COM (through CCW I
guess) the point is that exactly the same code compiled using 1.1 Framework
works perfect with Excel VBA, while recompiled on 2.0 Framework causes

installed VS2005 on my machine.
When I try to run the addin inside of VS2003, it just launches Word and

I've been trying to use c# to read .url files. Yes, I've read other
post, and yes, I've read Mattias and Eduardo Morcillo's posts, but
nothing. The code below is an amalgam of all those posts (and I've
tried many other variations...), but no joy. The code runs, throwing no

I couldn't find anything about this aspect in .NET.  Theory is all

I'm a .NET beginner and I need to write a COM Interop for ASP 3.0. I don't
know which language is more advantageous for a COM Interop: VB or C#? I'm
reading documentation on both languages and I have a feeling that
implementing COM Interop in VB maybe easier. Please advise.

Please advise me on how to interop the static (public) methods, fields,
properties etc. from C# to VB6. Pointers to any links are greatly appreciated.

I have a COM object and a .NET object that need to talk to each other.
The COM object creates the .NET object, but then the .NET object needs to
call methods in the COM object. It appears to me that the best way to do this
would be via connection points.

OK so weird scenario but it's what the client wants so here it goes...
I have a bunch of ActiveX/OCX controls which I have run through AxImp to
