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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

 ■ Custom controls extend the set of standard controls
   available in Visual Basic for MS-DOS. You access this
   custom-control functionality in Visual Basic via custom-
   control libraries (.LIB) and Quick libraries (.QLB).
 
 ■ Like standard controls, custom controls recognize a
   predefined set of properties, events, and methods.
   For more information on the specific features and
   functionality of a custom control, refer to the
   documentation that came with the control.
 
 ■ For more information on using custom controls, see
   Chapter 19 in the "Programmer's Guide."
 
 ■ For more information on creating custom controls,
   see Chapter 1 of "Professional Features"
   (Professional Edition only).
