Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

■ This error occurs after a Form_Load event procedure attempts
  to make a non-modal form visible.
 
■ Possible solution:
 
  • Unload or hide the modal form before trying to use the
    SHOW method on another form.
 
■ If you need additional help, move the cursor to a keyword
  and press F1 to open the Help window.
