Hi, I like to move a picture on the screen by clicking up, down, right, left arrow on the key board. Is there a way to get a notice in my software when “up arrow key” in keyboard is pressed, as an example. I tried bres=IsInputKey(0); How do I find out what key number is “up-arrow” Is this a right approach, I wonder. I use C, and C++ Languages on the platform of Windows10 and Visual studio 2017 Thank you in advance ChangChiTheGraphics

    You still have not said what type of project it is but since you say C (not C++) the implication is that it is a console program. See Reading Input Buffer Events - Windows Console. Try the sample program. There is much to learn but you can develop a relatively sophisticated text-mode UI Using the Console. That sample uses the KeyEventProc. In that when the arrow-up key is pressed ker.dwControlKeyState will be ENHANCED_KEY and ker.uChar.AsciiChar will be VK_UP.
