_WinAPI_SwitchDesktop ( $hDesktop )
| $hDesktop | Handle to the desktop. This desktop must be associated with the current window station for the process. |
| Success: | True |
| Failure: | False |
The _WinAPI_SwitchDesktop() function fails if the desktop belongs to an invisible window station. This function
also fails when called from a process that is associated with a secured desktop such as the WinLogon and ScreenSaver
desktops. Processes that are associated with a secured desktop include custom UserInit processes. Such calls
typically fail with an "access denied" error.
