>Can you execute a print preview with this method? From the dll I was never able to get a main vfp screen.

No I never tried. I have gotten some UI stuff to work like MessageBoxes but it is not advisible to do any UI stuff from an OLE server. And, AFAIK VFP 6 does not allow it at all.

You may want to make your server an Out-of-Process server, then you may be able to. But I have no experience in that arena.
