First available in version 3.0 build 2039.
flag - A boolean value that indicates whether the application icon should appear in the taskbar or not. Setting flag to TRUE causes a button to appear in the taskbar with your application's title and icon (this is the default mode of operation). Setting flag to FALSE will cause the taskbar button for your application to disappear. Valid values include: true and false.
No output parameters.
When this method is called synchronously, a return object containing the output parameters is returned to the caller immediately.
If you remove your application from the taskbar your users will not be able to use ALT+TAB to switch to your application. It will still be visible in the Task Manager under NT, Win2000 and XP.
