It would help if you would provide more details about what exactly you want
to use the new desktop for.  But in general, it is something along the
following basics (need more details to provide deeper examples):

    DWORD dwDesiredAccess = (DESKTOP_CREATEMENU | DESKTOP_CREATEWINDOW |
DESKTOP_ENUMERATE | DESKTOP_SWITCHDESKTOP);

    HDESK hDesktop = CreateDesktop("MyDesktop", NULL, NULL, 0,
dwDesiredAccess, NULL);
    HDESK hPrevious = OpenInputDesktop(0, FALSE, DESKTOP_SWITCHDESKTOP);
    ...
    SwitchDesktop(hDesktop);
    // use desktop as needed
    ...
    SwitchDesktop(hPrevious);
    CloseDesktop(hPrevious);
    CloseDesktop(hDesktop);

Thx REmy,
In fact I can switch to my newly created desktop.
The problem is that I have nothing(no windows) on this new desktop.
So what i want is a real and effective new desktop. Am i clear enough.?

Thank you

Nor should you yet.  All you have done so far is create a new empty desktop.
In order to actually display anything on it, you have to create your windows
within its context.  Look at the CreateWindowStation(),
SetProcessWindowStation() and SetThreadDesktop() functions as well.  Once
you have one of your process's threads associated with your new desktop, any
windows that you create in the context of that thread should appear inside
your desktop.

You'll need to start a new instance of Windows Explorer.  The first instance
of explorer on any desktop effectively controls the Windows "shell" - it'll
give you your Start menu and desktop icons.  If you use the CreateProcess
API call to start Explorer on the new desktop, make sure that you specify
the name of the desktop you wish to start Explorer on, in the STARTUPINFO
structure that is passed to CreateProcess.  That should do it for you.
