case WM_CONTEXTMENU:
        {
            UINT xPos = LOWORD(lParam);
            UINT yPos = HIWORD(lParam);

            RECT rc;
            GetClientRect(hDlg, &rc);

            POINT pt = {xPos, yPos};
            ScreenToClient(hDlg, &pt);

            if (PtInRect(&rc, pt))
            {
                      TrackPopupMenu(hmenu,TPM_LEFTALIGN,point.x,point.y,0,hwnd,NULL);

                return TRUE;
            } else
                return FALSE;
