    combined keyPresses

    Can you detect a combination of keys pressed with a KeyPressed event handler on a Windows.Form?
    I want to detect the UP and RIGHT arrow for example being pressed together (to move something diagonally)

    hi - i had a similar problem and posed the same question elsewhere.

    my reply was to use

    Code:
    public static bool IsKeyDown(Keys key)
            {
                return GetAsyncKeyState((int)key) < 0;
            }
    
            [System.Runtime.InteropServices.DllImport("user32.dll")]
            public static extern short GetAsyncKeyState(int vkey);
    then use something like

    Code:
    bool temp;
    
                if ((temp = IsKeyDown(Keys.Right)) && (temp = IsKeyDown(Keys.Left)))
    
                //do something here depending on keys ( right & left at same time in this case)
    this will return the state of every key on the keyboard allowing you to check for simultaneous key presses.

    hope this helps
