请问：在Ocx组件里用TrackPopupMenu 不能显示弹出菜单

     网页调用组件，在有的网页显示出得来，在有的网页不能显示出来。 --------------------编程问答-------------------- 在xp 上弹出菜单显示的出来，
在win2008上不能显示弹出菜单，iSelection 总是返回0
void CWebSignCtrlCtrl::DoRightClick()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());

CMenu   m_popmenu;
m_popmenu.LoadMenu(IDR_MENU1);

if (m_Lock=="1") {
m_popmenu.GetSubMenu(0)->ModifyMenu(ID_0_LOCK, MF_BYCOMMAND|MF_STRING, ID_0_LOCK, "解除锁定");
}

int iSelection = ::TrackPopupMenu(m_popmenu.GetSubMenu(0)->m_hMenu,TPM_LEFTALIGN|TPM_RETURNCMD,pMouse.x,pMouse.y,0,hWnd,NULL);

LRESULT lr = ::SendMessage(hWnd, WM_COMMAND, iSelection, (LPARAM)this);

}
--------------------编程问答-------------------- 看看和下面的情况是否有关联

Why doesn't my Context Menu dismiss properly when I click elsewhere ? [Context Menu, TrackPopupMenu(), Article, Visual C++] www.mooremvp.freeserve.co.uk 20-Sep-2001 by Bob Morre

Why doesn't my Context Menu dismiss properly when I click elsewhere ?

This is a known problem with TrackPopupMenu(). The cure is simple,
though somewhat obscure. Immediately before you call TrackPopupMenu, make a
call to SetForegroundWindow for your menu's owner window. Then immediately
after the call to TrackPopupMenu, post the same window a WM_NULL message.
Bizarre, but it works. Look at this sample code:

    HMENU hQuick = ::GetSubMenu (m_hUtility, IDM_QUICK);
    POINT CurPos ;
    GetCursorPos (&CurPos);

    SetForegroundWindow (); // Bodge

    TrackPopupMenu (hQuick,
                    TPM_LEFTBUTTON,
                    CurPos.x,
                    CurPos.y,
                    0,
                    GetSafeHwnd(),
                    NULL);

    PostMessage (WM_NULL, 0, 0); // Bodge
