ActiveX controls in VFP

I'm with you; I avoid ActiveX at all costs. The distribution, etc. is a pain. I'll supplement my apps with a standard DLL any day (eg. Graphics Server).
Delphi, CBuilder and Kylix (and even Paradox) got it right; they have their own "native" Visual Component Library that surpasses all the ActiveX **** out there.
Actually, you can build your own "TreeView" in VFP using a Grid, some grid line suppression, deleting/undeleting (expanding/collapsing) on the fly, and using a "graphics" Font (like FoxFont) for "connectors". "Indenting", after all, is simply adding a "leader" that is proportional to the "level" an item is located at.
A ListBox and an array can also be used to simulate a TreeView, though collapsing/expanding is not as easy as with a Grid ... However, "pruning and grafting" is easier with an array-based ListBox.
