When developing complicated print-outs, it is very convenient it you can see how they successively are created when stepping through the program in the debugger. Sometimes I use VPE with Delphi, and there it can be done with VPEngine1.RefreshDoc;. Probably, VPEngine1.OpenDoc; and VPEngine1.Preview; need to be executed before that works, but is a very useful function.

How can that be done with VPE4VDF? Send DoVpeRefreshDoc doesn't show anything. When I tried with Send DoVpePreviewDoc before DoVpeRefreshDoc I got error 57, stack memory full.
