When you call Close, any of four different things might happen. The form might get destroyed, it might get minimized, it might get hidden, or it might do nothing at all. That's determined by the Action parameter in the form's OnClose event. (It's also affected by the response to the OnCloseQuery event.) The default action for forms is caHide. If the form is the application's main form, then closing it will also terminate the program. If the form is an MDI child form, then the default action is caMinimize. When you call Release, you're telling the form to free itself, but not right away. Instead, the form frees itself _after_ it finishes processing any other messages that were sent to its window. The Release method is most useful when you're calling it from within one of the form's own event handlers, such as in response to a button or menu click on that form. Calling Release implies closing the form since it's going to get destroyed. I don't know whether OnCloseQuery and OnClose get called in that situation, but if they do, their responses aren't heeded. Release is usually compared to Free, not to Close. -- Rob ------------------------ Yahoo!
