SUMMARY
=======

SysTray.exe is an ActiveX control that is written in Visual Basic that
demonstrates how to add icons to the status area of the taskbar. SysTray.exe
also processes callback messages for taskbar icons. By using the new Visual
Basic 5.0 AddressOf function, the callback messages are received and processed
in a module that is registered as a callback function in a Win32 application
programming interface (API) call.

MORE INFORMATION
================

In Visual Basic version 4.0, you must use a Visual Basic intrinsic control to
serve as a Window that reacts to the callback message to manipulate the status
area of the taskbar. By using an intrinsic control in this way, you can work
around the inability of Visual Basic version 4.0 to work with pointers. For
additional information about this method, click the article number below to view

  Q162613 HOWTO: Manipulate Icons in the System Tray with Visual Basic

Because Visual Basic 5.0 can work with pointers, you do not need to use an
intrinsic control to add icons to the status area of the taskbar. Additionally,
the control contains properties and mouse events, such as MouseMove, MouseDown,
MouseUp, and MouseDblClick, to make the control more useful by specifying when
the icon appears, where the ToolTip text will be, and the icon image.
