I need to create a form with an animated GIF. This form will be used to do take patience for the user when a long operation perform. So, when I launch a long calculation operation, I need to show the form, do calc, and finally hide form. But, when calculation (or other operation) is done, I get only the form background. The GIF doesn't appear. Even with refresh, update, etc ... it doesn't work. Is there a solution to my problem?
Perhaps with Thread?
