虚心求教，如何控制弹出的MENU的位置。比如说向上弹出。

如题，谢谢。

CRect Rect;
GetDlgItem(IDC_BTN_MAIN_SYSTEM_MENU)->GetWindowRect(&Rect);
m_MainMenu.GetSubMenu(2)->TrackPopupMenu(TPM_RIGHTBUTTON|TPM_LEFTALIGN,Rect.TopLeft().x,Rect.TopLeft().y,this);

** Rect.TopLeft().x,Rect.TopLeft().y
这两个参数就是表示：
在这个矩形的左上方，即在举行的最上面弹出

BOOL TrackPopupMenu( UINT nFlags, int x, int y, CWnd* pWnd, LPCRECT lpRect = NULL );

nFlags设置下列值
TPM_CENTERALIGN
If this flag is set, the function centers the shortcut menu horizontally relative to the coordinate specified by the x parameter.
TPM_LEFTALIGN
If this flag is set, the function positions the shortcut menu so that its left side is aligned with the coordinate specified by the x parameter.
TPM_RIGHTALIGN
Positions the shortcut menu so that its right side is aligned with the coordinate specified by the x parameter.
Use one of the following flags to specify how the function positions the shortcut menu vertically.
TPM_BOTTOMALIGN
If this flag is set, the function positions the shortcut menu so that its bottom side is aligned with the coordinate specified by the y parameter.
TPM_TOPALIGN
If this flag is set, the function positions the shortcut menu so that its top side is aligned with the coordinate specified by the y parameter.
TPM_VCENTERALIGN

CMenu menu;
menu.LoadMenu(IDR_MENU3);
CPoint point ;
::GetCursorPos(&point);
::SetForegroundWindow(m_hWnd);// m_hWnd父窗口的句柄
menu.GetSubMenu(0)->TrackPopupMenu( TPM_LEFTALIGN,point.x,point.y,this,NULL);

BOOL TrackPopupMenu( UINT nFlags, int x, int y, CWnd* pWnd, LPCRECT lpRect = NULL );

lpRect 与此有关
