How to generate tlb file for a COM?

Built the COM dll on VC++ 6.0. Not very sure on how to build this .tlb file. Can someone share the experience on the use and the process to build it, please.

Thanks,

You must write an IDL file and use MIDL to compile it to a type library. IDL is its own language, so you'll have to learn it. If you add it to the project the compilation should be performed automatically.
