Hi Trey.

You need to use the syntax oCalendar.Object.Value.

As Ed pointed out, the way around this is to instantiate the objects at runtime, not design time. You can subclass them in a PRG if you need code in the ActiveX methods (you have to use a PRG rather than subclassing them visually the avoid moving the problem from a form to a VCX). I wrote an article about this issue in the June 1998 issue of FoxTalk -- my solution was a generic SFActiveX object that loads the appropriate ActiveX control at runtime. Let me know if you don't have a copy of the article handy.

Say hi to Bruce for me!
