Hi.
I have code in a Gotfocus of a control which does a Do MyF4Key

and in MYF4Key.prg have followng code:

If Pemstatus(_Screen.ActiveForm.ActiveControl,'ShowlookupWindow',5) = .T.
_Screen.ActiveForm.ActiveControl.ShowLookupWindow
Endif

This code is sued to run a Lookup piece of code.

However, I am getting the message :
ActiveControl is not an object if I hit the F4 key after selecting the screen to run . but just before it becomes visible. (My control is the first control on the screen)


It seems that if the Form is not actually active at the time I hit the F4 key, the message comes up.

Is there any way of testing to see if ActiveForm is an object , so I can avoid running the above code.

Regards,

Gerard
