>>I'm with Mike on this one. Your form must have an existing way of being closed. Why not handle the OnFormClosing event in the same way? The args will tell you what triggered the closure and you can still cancel it if you want. IMO that's much more in keeping with the normal user experience.....

>So you are saying that when a user clicks on the X in the upper right corner, the OnFormClosing will fire? If so, hopefully there is a call to disallow closing the form. Thank you.

Dmitry,

Did you read the thread I gave you in full or only the referenced message?
