C program in VB

Hi

I received the code of a interface written i C, but I can't program in C.
Can someone interpret me this in VB?

First off. The code is not written in C, but in C++ (MFC).
Second, it appears to be a dialog which is using the services of something
referenced by "m_pWELAPI", which is what I assume you meant by an
'interface'.

You will likely need to create a VB form and reference that object. How will
depend on what it is - a control, an API (dll), or ... With out more
information anything else would be a pure guess.

The fact it has something called a "VB_Connect" is interesting. Attempt to
reference the item and see what services are available in the ObjectViewer.
