GetIDsOfNames implementation

Hi all,

I need to implement GetIDsOfNames in my C++ application and I have no idea how to do that. I understand that I should implement GetTypeInfo, GetTypeInfoCount for that. I found a code sample which uses LIBID, but I don't have LIBID, and I don't know where to get one.

What I really need is a good explanation of IDispatch interface internals...

+1 A:

Check the OLE Automation Protocol

As to GetTypeInfo, GetTypeInfoCount, why these functions are required, where are those type information used?

Required for late binding languages like VB or javascript. Do you want to support these languages?

This is not a good explanation of IDispatch internals, but if you have an .idl file for your interfaces you can generate a type library and include the latter into the COM server, then just use IDispatchImpl than will do the work for you.
