I need to click a button on a form, check to see if a set of files exist, if they don't create them, when they are done let the button finish it's code. The creation process may take a minute or so. Would it be a wise idea to use a modal form to display some sort of progess. Then based on the out come let the calling form have the control back to finish the process. I haven't used modal forms in my app but this may be a case where it is needed.
