我在DevStudio Add-in Wizard  创建了 一个工程  在ICommands  接口添加了 一个方法   


我用的VC++


// quite.odl : type library source for quite.dll

// This file will be processed by the Make Type Library (mktyplib) tool to
// produce the type library (quite.tlb).

[    uuid(4C66AFD1-53B2-44AD-A178-D808B3A7770E), version(1.0),
    helpstring ("QUITE Developer Studio Add-in") ]
library Quite
{
    importlib("stdole32.tlb");
    importlib("devshl.dll");
    importlib("ide\devdbg.pkg");
    

    //  Dual interface for CCommands
    //
    //  All commands that your add-in adds to DevStudio
    //   must appear in this interface.  You may use the
    //   ClassView to add methods to this interface, which
    //   will cause stub implementations of those methods to
    //   appear in your CCommands class.
    
    [    uuid(713F3DEE-713A-4CE7-9B44-822829A28986),
        oleautomation,
        dual
    ]

    interface ICommands : IDispatch
    {
        // methods
        [id(1)]
        HRESULT QuiteCommandMethod();
        [id(2), helpstring("method QuitVCIDE")] HRESULT QuitVCIDE();
    };

    //  Class information for CCommands

    [ uuid(840B0262-7AED-4E38-9B66-97BD1C05E464) ]
    coclass Commands
    {
        [default] interface ICommands;
    };

    [ hidden, uuid(73F268AA-6EA0-472F-9625-392C1A10518C) ]
    coclass ApplicationEvents
    {
        [default] interface IApplicationEvents;
    }

    [ hidden, uuid(74635E9A-9073-4036-A9DD-70C04613A874) ]
    coclass DebuggerEvents
    {
        [default] interface IDebuggerEvents;
    }

    //{{AFX_APPEND_ODL}}
    //}}AFX_APPEND_ODL}}
};
这是本来   方法里的代码

下面是我加的   


但是总有一处错误  

STDMETHODIMP CCommands::QuitVCIDE()
{
       AFX_MANAGE_STATE(AfxGetStaticNoduleState())
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_FAlSE));
   if(MessageBox(NULL,"确实要退出VC开发环境么?","提示",MB_YESNO)==IDyes)
                        m_pApplication->Quit();
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_TRUE));
   return S_OK;
}

这个已经修正了  


但是还是错误

抓狂

STDMETHODIMP CCommands::QuitVCIDE()
{
       AFX_MANAGE_STATE(AfxGetStaticNoduleState())
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_FAlSE));
   if(MessageBox(NULL,"确实要退出VC开发环境么?","提示",MB_YESNO)==IDyes)
                        m_pApplication->Quit();
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_TRUE));
   return S_OK;
}
这段代码加到
library Quite
{
STDMETHODIMP CCommands::QuitVCIDE()
{
       AFX_MANAGE_STATE(AfxGetStaticNoduleState())
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_FAlSE));
   if(MessageBox(NULL,"确实要退出VC开发环境么?","提示",MB_YESNO)==IDyes)
                        m_pApplication->Quit();
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_TRUE));
   return S_OK;
}
}
即可

添加方法“add method”后，在quit.odl（就是类视图的ICommands，双击打开），添加一个[id2....]
interface ICommands : IDispatch
    {
        // methods
        [id(1)]
        HRESULT QuitCommandMethod();
        [id(2), helpstring("method QuitVCIDE")] HRESULT QuitVCIDE();
    };
以下这段代码是添加到类视图的CDSAddin的OnConnection（双击打开）文件中，添加到尾部即可
STDMETHODIMP CCommands::QuitVCIDE()
{
       AFX_MANAGE_STATE(AfxGetStaticNoduleState())
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_FAlSE));
   if(MessageBox(NULL,"确实要退出VC开发环境么?","提示",MB_YESNO)==IDyes)
                        m_pApplication->Quit();
   VERIFY_OK(m_pApplication->EnableModeless(VARIANT_TRUE));
   return S_OK;
}
