Override OnNcHitTest and return HTCAPTION if the mouse is where you want the

Hi,
I have created a dialog based application without a title bar, and
want to move the dialog using the left mouse button.
I tried MoveWindow nut the window was streching instead of moving !!!
Can anyone help me please?

Hi and thanks for your help.
I did it with the following two handlers:

void CYourDialog::OnLButtonDown(UINT nFlags, CPoint point)
  {
     CDialog::OnLButtonDown(nFlags, point);
     PostMessage( WM_NCLBUTTONDOWN, HTCAPTION,
          MAKELPARAM( point.x, point.y));
  }

  // Handler for WM_NCHITTEST message

  LONG CYourDialog::OnNcHitTest( UINT uParam, LONG lParam )
  {
     int xPos = LOWORD(lParam);
     int yPos = HIWORD(lParam);
     UINT nHitTest = CDialog::OnNcHitTest(CSize(xPos, yPos));
     return (nHitTest == HTCLIENT) ? HTCAPTION : nHitTest;
  }

can anyone tell me more about waht is happening in them ( I am a
newbie).
