MFC 弹出式菜单并分别为两个子菜单添加消息响应函数

右键点击，弹出式菜单为轿车和人两项，如果点击轿车，会在界面上显示，但是同样的写法，点击人的时候就没有消息响应

void CScoolGateView::OnRButtonDown(UINT nFlags, CPoint point)
{
CMenu menu;
if (menu.CreatePopupMenu())
{
menu.AppendMenu(0,ID_DRAW1,"轿车");
menu.AppendMenu(MF_SEPARATOR,0,"");
menu.AppendMenu(2,ID_DRAW2,"人");

CPoint pt;
GetCursorPos(&pt);
menu.TrackPopupMenu(TPM_RIGHTBUTTON,pt.x,pt.y,this);
}

CView::OnRButtonDown(nFlags, point);
}

void CScoolGateView::OnCar()
{
// TODO: Add your command handler code here
UpdateData(TRUE);
CDC*pDC=GetDC();
BITMAP bitmap6;
CBitmap bm6;
bm6.LoadBitmap(IDB_BITMAP6);
bm6.GetBitmap(&bitmap6);

CDC dc6;
dc6.CreateCompatibleDC(pDC);
dc6.SelectObject(&bm6);
pDC->BitBlt(350,545,350,400,&dc6,0,0,SRCCOPY);
ReleaseDC(pDC);
MessageBox("请进");

}

void CScoolGateView::OnPerson()
{
// TODO: Add your command handler code here
UpdateData(TRUE);

CDC*pDC=GetDC();
BITMAP bitmap7;
CBitmap bm7;
bm7.LoadBitmap (IDB_BITMAP7);
bm7.GetBitmap (&bitmap7);
CDC dc7;
dc7.SelectObject(&bm7);
dc7.CreateCompatibleDC(pDC);

pDC->BitBlt(350,545,1000,500,&dc7,0,0,SRCCOPY);
ReleaseDC(pDC);
MessageBox("请进");

}
