Hi, I have this weird problem where I must use a CDC to draw to my application. I want to draw on the desktop. If I get the desktop DC, I can draw on it without any trouble. However, I am not using directx. To use directx, I tried getting the desktop HWND but when I pass it to directx's CreateDevice, it does not work properly. It will not draw on the desktop. Maybe I have to update the HWND or something but I"m not really sure. Anyway, is there someway I can use directX with a CDC instead of an HWND?

I don't think you want a device context. But maybe you shouldn't be getting the desktop HWND, but one for the window you want to draw on? What currently happens - some DX rendering or nothing at all?

nothing happens. if I switch the Hwnd with one to an actual window, it works fine. But I want to draw on the desktop (ie, on icons and they background, ect.), not on a window.
