Switching Primary and Secondary Display.

Hi,

I have to switch the primary and secondary display. For this I tried:

Code:

---


        DISPLAY_DEVICE        disdev;

        ZeroMemory(&disdev, sizeof(disdev));
        disdev.cb = sizeof(disdev);
        int x, flags ;

        EnumDisplayDevices(NULL, 1, &disdev, 1);
        //
        flags = CDS_SET_PRIMARY | CDS_UPDATEREGISTRY |CDS_RESET;
        x = ChangeDisplaySettingsEx(disdev.DeviceName, NULL, NULL, flags, NULL);

---

Well, it didn't work, although I get a successful as return value.

I tried all kinds of different flags but it never works (although I always get a successful return value).

Could anyone please help me with this ?
