Hi Barbara,

>Christof's suggestion was correct. However, if the control is .Null, his code will give you .T. back but your base class code will still bomb. You'll need to check to see if the value is .Null, OR, and simpler, check to see if the the control NAME is type "C"

How do you set a control to NULL? *g* The only way I ever got this was when I manually decreased the internal object reference counter.

For actual objects, TYPE("object") is sufficient. Of course, if we are dealing with object reference properties, as well, than you need some more checking as you have indicated.
