Handle WM_NCHITTEST and always return HTCAPTION.

Just a little aside note. "Moving your window by dragging it by clicking on anywhere on the dialog" is OK in one particular case: it has no menu, no system menu, no maximize/minimize/close button, no scrollbars and is not resizeable. Returning always HTCAPTION from WM_NCHITTEST message handler leads in the impossibility of using menus,... and all enumerated above. A little bit better approach is to apply the trick only for the client area. Here is an example:

UINT CMyDialog::OnNcHitTest(CPoint point) 
{
   UINT nRet = CDialog::OnNcHitTest(point);
   if(HTCLIENT == nRet)
   {
      nRet = HTCAPTION;
   }
   return nRet;
}

Add the following line of code in your LButton Down handler. PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x, point.y));
