右键菜单加载问题

Question

2. 我在资源里定义了一个菜单ID为：IDR_MENU1，然后在视图的OnRButtonDown()里，设置一个右键菜单，这样会出错：
ClientToScreen(&point);
CMenu menu;
if(menu.CreatePopupMenu())
{
menu.LoadMenu(IDR_MENU1);
menu.TrackPopupMenu(TPM_RIGHTBUTTON,point.x,point.y,this);
}
而这样就不会：
ClientToScreen(&point);
CMenu menu;
if(menu.CreatePopupMenu())
{
menu.AppendMenu(MF_STRING,111,"A");
menu.TrackPopupMenu(TPM_RIGHTBUTTON,point.x,point.y,this);
}
右键菜单不可以LoadMenu吗？应该不会吧，那问题出在哪里呢？

Answer 1

ClientToScreen(&point); 
CMenu   menu, *pmenu = NULL; { 
   menu.LoadMenu(IDR_MENU1); 
   pmenu = menu.GetSubMenu(0);
   if(pmenu)
     pmenu->TrackPopupMenu(TPM_RIGHTBUTTON,point.x,point.y,this); 
} 

Answer 2

CMenu oMenu;
                if (oMenu.LoadMenu(IDR_MENU1))        
                {
                    CMenu* pPopup = oMenu.GetSubMenu(0);
                    ASSERT(pPopup != NULL);
                    CPoint oPoint;
                     GetCursorPos( &oPoint );
                    SetForegroundWindow();
                   pPopup->TrackPopupMenu(
                        TPM_LEFTALIGN | TPM_RIGHTBUTTON,
                        oPoint.x, oPoint.y, this); 
                }
            }
            break;

Answer 3

LoadMenu
CreatePopupMenu
是不同创建菜单句柄的方法，
你已通过CreatePopupMenu创建了菜单，此时是空菜单，只能通过AppendMenu,InertMent来增加菜单项
