- One way is to make a control, change the visible property to false, and use it's event procedures to transmit the message.
-
- For example, a hidden textbox can be used. Then the Text1_Change event sub

- empty itself.)

- The property Form.WindowState gives this information. (0 = Normal,
- 1 = Minimized {iconic}, 2 = Maximized.)
