Hi Keith,
Sorry for the late answer, I was in vacation.
Thank you for your hints.
Unfortunately the code is not helpful, because I already wrote the program in VBS, VB and in C#.
Everything works, but C++.
Please find my little C++ project attached.
It works until I try to access the IVdComp object.
At least you can use it as a template for other Viewdraw programs.
Possibly you get my problem fixed, that would be great.
Ciao, Brösel
