SetThreadDesktop function

Assigns the specified desktop to the calling thread. All subsequent operations on the desktop use the access rights granted to the desktop.

Syntax


BOOL WINAPI SetThreadDesktop(
  _In_  HDESK hDesktop
);

Parameters

hDesktop [in]

A handle to the desktop to be assigned to the calling thread. This handle is returned by the CreateDesktop, GetThreadDesktop, OpenDesktop, or OpenInputDesktop function.

This desktop must be associated with the current window station for the process.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The SetThreadDesktop function will fail if the calling thread has any windows or hooks on its current desktop (unless the hDesktop parameter is a handle to the current desktop).

Warning  There is a significant security risk for any service that opens a window on the interactive desktop. By opening a desktop window, a service makes itself vulnerable to attack from the logged-on user, whose application could send malicious messages to the service's desktop window and affect its ability to function.
