im writing a program where i need to pick a color from a pixel anywhere on the screen. i found a dll which will let me do it by clicking on the screen only.
i need to know how to pick it via pixel coordinates.
could anyone point me in the right direction to some source or reading material on the net??

btw i am running VB6.

any help would be greatly appreciated.

Probably at some point the Mouse Click is converted to cordinates. Instead of converting mouse cordinates, enter your own.

Use the API... C++...

GetPixel
The GetPixel function retrieves the red, green, blue (RGB) color value of the pixel at the specified coordinates.

COLORREF GetPixel(
HDC hdc, // handle to DC
int nXPos, // x-coordinate of pixel
int nYPos // y-coordinate of pixel
);

Look in the API Viewer that comes with VB6 to find the correct translation to VB from C.

To get the hdc of the Screen ... use Screen.hdc

Good luck!

no the DLL doens't allow me to enter my own co-ordinates
it has only one function in it and it has code which directly takes the mouse from the screen.

i will check out the API as soon as i get a chance, thanks for the idea
