I'v get it!
protected override void WndProc( ref Message m )
{
const int WM_NCLBUTTONDOWN = 161;
const int WM_SYSCOMMAND = 274;
const int HTCAPTION = 2;
const int SC_MOVE = 61456;
if ( (m.Msg == WM_SYSCOMMAND) && (m.WParam.ToInt32() == SC_MOVE) )
return;
if ( (m.Msg == WM_NCLBUTTONDOWN) && (m.WParam.ToInt32() == HTCAPTION)
)
return;
base.WndProc( ref m );
}
