Question

我不是使用pCmdInfo->lpVerb的agnaist但我的问题是当我们动态创建rightclick子菜单时我们将如何处理这种情况。例如，我有以下情况：

if(strcmp(cRegKeyVal,"Connected")==0)
    {
        //g_bConnectStatus=TRUE;
        InsertMenu ( m_hSubmenu , 0,  MF_BYPOSITION|MF_GRAYED, m_uCmdID++, _T("Connect") );
        InsertMenu ( m_hSubmenu , 1,  MF_BYPOSITION, m_uCmdID++, _T("DicConnect") );
        InsertMenu ( m_hSubmenu , 2,  MF_BYPOSITION, m_uCmdID++, _T("Configure") );
        InsertMenu ( m_hSubmenu , 3,  MF_BYPOSITION, m_uCmdID++, _T("Menu4") );
        InsertMenu ( m_hSubmenu , 4,  MF_BYPOSITION, m_uCmdID++, _T("About") );
    }
    else
    {
        //g_bConnectStatus=FALSE;
        InsertMenu ( m_hSubmenu , 0,  MF_BYPOSITION, m_uCmdID++, _T("Connect") );
        InsertMenu ( m_hSubmenu , 3,  MF_BYPOSITION, m_uCmdID++, _T("Help") );
        InsertMenu ( m_hSubmenu , 4,  MF_BYPOSITION, m_uCmdID++, _T("About") );
    }
..  
..  
InsertMenuItem ( hmenu, uMenuIndex, TRUE, &mii );
}

现在如果我使用pCmdInfo->lpVerb开关案例，如下所示，那么Case 1正在执行我是否点击 DisConnect （菜单项已插入）在如果条件在上面的代码段中）或 Help （菜单项插入 Else 部分，如上面的代码段）

switch ( LOWORD( pCmdInfo->lpVerb) )
        {
        case 0:
            {
            //Your Logi for Case-0
            }
            break;
        case 1:
            {
        //Your Logi for Case-I      
            }
        break;
      }

您应该在QueryContextMenu中存储菜单项标识符（或偏移量？），以便稍后在InvokeCommand中使用：

QueryContextMenu()
{
    m_uConnectId = m_uCmdID++;
    InsertMenu( m_hSubMenu, "Connect" );
    m_uHelpId = m_uCmdID++;
    InsertMenu( m_hSubMen, "Help" );
}

InvokeCommand()
{
    ULONG uCmdID = LOWORD( pCmdInfo->lpVerb );
    if( uCmdID == m_uConnectId )
    {
        // do "Connect"
    }
    else if( uCmdID == m_uHelpId )
    {
        // do "Help"
    }
}

我们可以在不使用pCmdInfo-＆gt; lpVerb的情况下执行rightclick
