    Question key activated script

    How do I make a program detect which key is pressed, and depending on the key that's pressed it would execute specific script?

    For example, if you press 'h' the script 'Beep(2000,500);' would be activated - but if you press any other keys nothing would happen.

    Thanks in advance.

    Sorry if im wrong because im just starting, but since the CALLBACK function is used each time a key is pressed, cant you put a switch statement in the function to handle the letters you want, then each letter adds special things to a new message.

    chapter #6 in petzold gives good examples on how to handle WM_CHAR and WM_KEYDOWN messages.

    Thanks, for you'r help guys, I don't know if this is the right way of doing it all I know is that this way works!

    Code:
    if(GetAsyncKeyState(VK_RIGHT)){ // If right arrow key is pressed...
    Beep(2000,300); }
    else{}
