Close Button not Working

[E. Heineken]

The close buttons (the "x" on the top right corner of the forms) are sometimes not responding. But I'm very sure that the forms are working fine, becoz I got command buttons that can close the forms. Is there any solution to this? Thanx.

Is there any pattern to when they do not work?

I have multiple forms on my application. I suspect that it is because of the way I open up the forms? (coz I open and close them by setting the visible property) Actually is there any ways that I can set the function of those close buttons?

Put a breakpoint in the QueryUnload event of the form and check to see if unloadmode =0 (This means that you have clicked the "x").
I can't think of any reason that this wouldn't work but maybe you should consider using form.show and form.hide.

I found out that when I hardcode the display of the contents on the textbox controls on the form, the "x" button doesn't respond. But when i leave the textbox displays alone, the button now works. That's odd.....
