ComClasses in C#
is there an equilent of this in c#? If not how to proceed to get the same
functionallity to be able to expose the com class?

Hello,

I think from what you are asking you want to use C# to create a component
that appears to be a COM object - usable with classic VB and Component
Services etc. Your explanation is a little vague...

If so you need to create a CCW (COM Callable Wrapper) for your class. This
allows .Net apps use it as a .Net object, and COM clients as a COM object.

The process is roughly:

1 - Create your class (DLL)
2 - Create an interface to it
3 - Add some COM specific attributes
4 - Mark your class as implementing the interface

Note there are some limitations eg: you can't expose C# public static
methods using an interface (something I spent the last few days working
around).

I'll let you mull over that for a while. If you are stuck post back and tell
us how far you got.

Cheers!
