This is the interface and demo for Visual Basic 4.0

Here is only a part of vpedemo implemented.
Of course, all other demos are possible.

The biggest disadvatage of VB is, that you aren't able to receive 
windows-messages.

So you're not notified, if the user has closed a VPE window.
Because of this, the user-close-option for VPE windows has been
disabled (flag: VPE_NO_USER_CLOSE).

This isn't very fine, and we strongly recommend to use the message
blaster ocx / vbx control to work with these messages and have the
full functional user-interface.

Look at the C++ example (vpedemo.cpp), how to work with messages.

If you do not show any previews, this all doesn't apply to you.
