COM related questions

I have a source code of a program using a compiled tlb file
the file as I extracted into VC++ includes structs that do not define themselves (as I saw them in tlh and tli)

I see in VB source code of the program the lines

Dim a as IUnknown
//.... and in form-load
Set a = New StructName


I do similar in C++ as
IInterface i=new StructName();
and get an error stating StructName has no appropriate constructor.

I read all the VB files I was given and couldnot find where the (Co)CreateInstance is used. I don't find any COM functions only the compiled interfaces are freely easily used as some normal classes.
I guess they want to freek me out by not having sent me all required files. :( They discriminate me!

Thank you.

Huhu :cry: I see this problem is too easy, how come you can't find a soluytion ?
When I was in coollege people did that on me too. :cry: Those are arrssholes
Yes, not enough files of course. Could you post it here ?

Is there a question there? If you have source code, then you can re-compile it. If you have a C++ question, we have a forum for that, too. This is VB6
