According to the VFP online help, .dll-based COM objects ALWAYS allow modal events.

VFP COM Object aren't ActiveX controls; an in-process COM server can't have any UI code in it; while an out-of-process server can, it won't participate in the event loop of the application that references it.

>Why can't I display a form from within a .dll based VFP com component?

Because it's an in-process OLE Automation server and not an ActiveX control.

>Why doesn't the help file discuss error code 1031?

I have no idea.
