How do I create a message-only window from windows forms?

Question

I\'m trying to create a message-only window to receive window messages from an MFC library class, within a winforms application.

I\'ve tried subclassing NativeWind

Try that :

[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

static IntPtr HWND_MESSAGE = new IntPtr(-3);

protected override void OnHandleCreated(EventArgs e)
{
    base.OnHandleCreated(e);
    SetParent(this.Handle, HWND_MESSAGE);
}
