Ok, I was wrong on how QueryUnload() works....I'd still use it to handle the "x" button, but it works like this

If Not this.IsOkToExit()
  NoDefault
EndIf

and it only works from the x button...

As for the event binding, the only thing I can think of that would mean the least amount of coding is this:
Add a property to the form called lIsOkToExit. It will be .T. or .F.
In your IsOkToExit() method, set the lIsOkToExit property to the return value, prior to returning it.
In the form's Release() method, check the flag and issue a NoDefault if the flag is .F.
e.g.

**---- IsOkToExit()
** determine if it's ok here **

this.lIsOkToExit=llOK
Return llOK


**---- Release()
If Not this.lIsOkToExit
  NoDefault
EndIf

If you use the QueryUnload() keep it pointing to the IsOk() method and not the flag.

>Trey,
>Thanks for the answer. I was using this case as an example. The IsOkay() method is being bound to many different controls on the form. Any thoughts? I don't really want to write and maintain a check like the one you described in several places. Thanks again,

>>>Hello,
>>>Lets say I have a piece of code that returns .T. or .F. depending on if it is okay to close a form or not. Now, the exit button on the form just calls the forms release method. So, I bind the click of the button to the IsOkToExit method on the form. The method, in this case, returns .F., how to I halt the execution of the button's code? Thanks,
