Get the color of a pixel

How can I get the color of a pixel on the screen? Not on my application, anywhere on the screen.
I know I have to use GetPixel, but how do I get the device context, that includes everything on the screen?

C++, Win32, Dev-C++

You can open the display as a DC:

Code:

---

CreateDC("DISPLAY", NULL, NULL, NULL);

---

You can use GetDC and pass NULL as its parameter

Thanks, I'll test these as soon as I can.

Perhaps the GetPixel() function? This is a link to something I did before. Look at it, and modify it to your needs -

Code:

---

GetDC(HWND_DESKTOP);
// stupid code tags
