C# Keyboard hooks, keys up event

Question

I have a C# function that I'm trying to figure out, here is the code :

private int KbHookProc(int nCode, IntPtr wParam, IntPtr lParam)
    {
        if (nCode >= 0 && wParam == (IntPtr)WM_KEYDOWN)
        {
            var hookStruct = (KbLLHookStruct)Marshal.PtrToStructure(lParam, typeof(KbLLHookStruct));

            bool ctrlDown = GetKeyState(0xA2) != 0 || GetKeyState(0xA3) != 0;

            if (hookStruct.vkCode == 0x56 && hookStruct.KF_REPEAT == 0)
            {
                Clipboard.SetText(" ");
                MessageBox.Show("Hit ?);
            }                
        }

        if (nCode >= 0 && wParam == (IntPtr)WM_KEYUP)
        {
                MessageBox.Show("Message : KEY UP");
        }

        // Pass to other keyboard handlers. Makes the Ctrl+V pass through.
        return CallNextHookEx(_hookHandle, nCode, wParam, lParam);        
    }

so what I'm looking for here is to figure out how to fire the event when the L_CTRL + V button are pressed. It is working; however I only want the event to fire after the keys are up, and for that I am lost. Can anyone offer any direction?

If you only want to respond when the keys are released, then only respond to the WM_KEYUP message.

Remove the portion of your if statement that handles the WM_KEYDOWN message.
