Windows API Hook Notification when Capturing Display
Posted on 2009-05-09
I am writing a program that writes pixels to the main display background on windows. I can write the pixels, but I also need to know when this information is captured. I have a low level keyboard hook that is triggered when the print key is pressed. Is there any api hook or other way to be notified when any program calls CreateDC("DISPLAY", "", "", "") to get the main display window?
