This is off-topic, not related to C programming. This is the question at the level of the Windows user. Please refer to the Windows documentation.

Check the documentation[^]. And please do not just say "it does not work", as that gives us no idea what your code is doing, or what results you see.

I thought the MSDN article you mentioned was clear.

http://msdn.microsoft.com/en-us/library/windows/desktop/dd145179%28v=vs.85%29.aspx[^]

When your program starts, it is associated with a Windows desktop. Any monitors not associated with that desktop won't be accessible. You say " can not let the monitor work in the mode of large desktops.". I take that to mean you don't want the monitor added to the default desktop.

Solution: create a separate desktop for your independent monitor.

You can create multiple desktops and flip between them.

If the other monitor is already attached to a different desktop, your program will need to attach to it before attempting to create a window under that desktop's window space.

The monitor may be in the current Window station or not. See ...
