>Simple question, but giving me a hard time. How do I disable or enable a command button using the THIS or THISFORM command. The command button is in a form and I want to have the button enabled only if the user needs to use the button. In other words, how do I reference the enable/disable options using the THISFORM command. Thanks, Mike.

The way I usually do it is the REFRESH method of the button itself, i.e. THIS.ENABLED=IIF(THISFORM.MyProperty=.T.,.T.,.F.)

Now call MyButton.Refresh when Myproperty changes.

Same thing could be achieved with

LPARAMETERS SetActive
THIS.ENABLED=IIF(SetActiveOnOff,.T.,.F.)

Call with THISFORM.MyButton.Refresh(.T.) or (.F.), as it were.

Hope this did it, write back otherwise.
