Can you not just set an object variable for the object, and test that it is
not Nothing.

Hello Group,



When distributing Excel projects with non-standard activeX controls I need
to make sure that they're installed before calling the control.

For example, the calendar control is a nice control, but it can be missed
if
not available. I would like to check if the calendar is available, and
only
then call it.



Does anybody know if this can be checked with Excel VBA, and how?



Thanks a lot.
