Hello.

I have a Visual Basic 6 program that calls a C++ DLL that I am in the
process of writing.   The DLL does some calculations and should draw some
points in a Picture form contained in the VB exe.  How can I scale the
Picture form to a custom scale from the C++ DLL, so that the points are drawn
in the right place?

Note: I am currently passing the picture's hDC tag to the DLL, but I don't
know what to do with it.  Can I use some version of the SetWindowExt,
SetViewportExt, and SetViewportOrg functions?

Any help would be much appreciated.  Thanks.

Nikolai.
