Hi,
I want to turn Windows extended desktop on/off programatically. I am using Windows XP Home and Visual C++.
Thank you

You can do this with the SecondaryDisable and SecondaryEnable methods of the IUltraMonSystem interface.
Usually you would also want to save and restore the positions of windows and desktop icons, here's some sample code which demonstrates this:
IUltraMonSystem* pSys = 0;
CoCreateInstance(CLSID_UltraMonSystem, 0, CLSCTX_ALL, IID_IUltraMonSystem, reinterpret_cast(&pSys));
// disable secondary monitors
pSys->SavePositions(POS_ALL);
pSys->SecondaryDisable();
// enable secondary monitors
pSys->SecondaryEnable();
pSys->RestorePositions(POS_ALL);
See the Programming Guide for C++ in the SDK documentation for more information on the required headers etc.
