Hi

I have overriden WndProc to detect when the key is pressed. Because it
didnt work i inserted debug code to detect what messages pass through
the WndProc exactly.My application is minimized in taskbar and visible
via notifyicon. When I run the program :

protected override void WndProc(ref Message m)
{
System.Diagnostics.Debug.WriteLine(m.Msg);

base.WndProc(ref m);
}

I see :

....and no more messages pass through WndProc. I need to catch windows
message when user presses Control twice. Why no more messages pass
through the WndProc and how to catch control presses twice?

The key down event would only occur if your window has focus, which it
doesn't. What you need is a global keyboard hook. I don't recall how to do
it, but two method names I do recall are SetWindowsHookEx and
CallNextHookEx.
