ProcessCmdKey - wait for KeyUp?

Question

I\'m having the following issue in a WinForms app. I\'m trying to implement Hotkeys and I need to process Key messages whenever the control is active, no matter if the focus

Answer 1

const int WM_KEYDOWN = 0x100;
const int WM_KEYUP = 0x101;

protected override bool ProcessKeyPreview(ref Message m)
{
    if (m.Msg == WM_KEYDOWN && (Keys)m.WParam == Keys.NumPad6)
    {
        //Do something
    }
    else if (m.Msg == WM_KEYUP && (Keys)m.WParam == Keys.NumPad6)
    {
        //Do something
    }

    return base.ProcessKeyPreview(ref m);
}
