Introduction
This example uses the gdi32.dll function GetPixel to return the RGB pixel value from any pixel on the screen based on an x and y position. To do this, a call was also made to the user32.dll GetDC function to get the handle to the device context (HDC) for the entire screen.
Steps to Complete
Open attached VI.
Specify the desired X and Y position.
Additional Notes
This example uses the gdi32.dll and the user32.dll. Both will need to be installed to run this example.
