I would like to force the user to enter a value in the combo box before clicking the add button. Is there an easy way to do this other than programmatically enabling and disabling assorted controls? The lost focus event wont let you set focus back to the calling control. Other ideas?
Hans,

You certainly can use the lostfocus event to setfocus back to the same control.

* Lostfocus event
IF SomeCondition
   This.SetFocus()
   NODEFAULT  &&Critical to getting it to work
ENDIF

You must issue a NODEFAULT to stop fox from doing its default of moving focus after you have set it elsewhere.
