Thanks Cindy. I'll tear into the VFP8 Toolbox code and see what I can use.

>>... I want to drag a field onto my target form in design mode. This works like a champ if the target form is instantiated with CreateObject(), but not in design mode. The DBC manages to do this, but I don't know how. In short, runtime lets me drag and drop, but not invoke a builder. Design time lets me invoke a builder, but not drag and drop. That's the problem. Thanks.
