How can I use these files in VB6?

Hello,

I have a C++ project, but I don't know much C++. I would like to have
the application in VB6 for better understability and debugging. The
project consists of about 10 .dsw files (C++), and they compile to .lib.
Can anybody please tell me if it's possible to use them in VB6, maybe
like a DLL or so?
The project is rather huge, and rewriting it would be an awful lot of work.

Thank you.
Tom

You didn't say what kind of "lib" the project compiles to.

But yes, a VC++ programmer should be able to convert or wrap a ".lib" file
into a regular 'WinAPI' Dll, or an ActiveX component either of which could
be used from a VB application.

Assuming the code structure is such it would be amenable to be contained
in a DLL, there's no reason you couldn't recast that portion as a DLL,
no. You would, I think (others can correct me if I'm overstepping my
knowledge of C++ which is undoubtedly even less than yours :) ) have to
build an interface C-style wrapper using stdcall to interface to VB or
do that in the C++ code itself.

Other than that, "piece o' cake"! :)

Is this an open source project? If so, can you post the link?

What does this project do? Perhaps there is a VB equivalent.

Do you have VC? If so, which version?

Finally, open one of the DSW files with Notepad, and post the version number
which is in the first line.
