    GetAsyncKeyState(int vKey) - Problem

    Anyone know of a way to empty the buffer after using the GetAsyncKeyState() function? If I can't empty
    it after each function call the program will behave badly.... I am looping a few functions, including that one. It seems to register more than one keypress sometimes and I don't know what to do about it.
    I would appreciate any help greatly.

    Have you tried setting the parameter to zero? That might work, but I doubt it, it's worth a go anyway. It obviously isn't going to work if there is a key with the "ID number" of zero.

    I am not sure about this, but I don't think the problem is with GetAsyncKeyState but rather your code. Notice the async in the word "GetAsyncKeyState".

    Thx for your replies. I found a solution... Yes MadCow you were right.. it was my code..
    when I did it like this:

    if (GetAsyncKeyState(0x25) == -32767){
        insert code here
    when I checked the return value to see if the button had been pressed it worked fine..
    before this it must have checked both button presses and if any button was held down.
