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 the article in the Microsoft Knowledge Base: 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.
