Repurpose Word button callback problem in C++/ATL RRS feed

  • Question

  • I followed this document on repurposing Word buttons and was able to successfully do so in a VSTO c# project.

    I'm trying to work this into a legacy word plugin project written in C++/ALT.

    For the ribbon xml I have:

    <command idMso='Cut' onAction='MyOnAction'/>

    in the IDL  I have:

    [id(1), helpstring("method MyOnAction")] HRESULT MyOnAction([in] IDispatch* pRibbonCtrl, [in,out] VARIANT_BOOL *fCancelDefault);

    and in Connect.cpp I have

    STDMETHODIMP CConnect::MyOnAction(IDispatch* pRibbonCtrl, VARIANT_BOOL* bRet)
    MessageBox(NULL,"I'm here!","APP",MB_OK);
    *bRet = VARIANT_FALSE;
    return S_OK;

    I never actually see the message box when Bold is clicked. In addition, the selected text does NOT  become Bold either (no error reported)

    I searched online and found a few discussions dating back to 2010, claiming that the callback for onAction signature is actually incorrect ( and should be:

    STDMETHODIMP CConnect::MyOnAction(IDispatch* pRibbonCtrl, VARIANT* bRet)

    I tried this too but observed the same behavior. 

    Any help would be appreciated!

  • Hi epochdave,

    I tested this but I was also unable to get it to work.  If nobody else in the community has any suggestions, the only thing I can suggest is to open up a support case with us to we can investigate further.  Sorry I couldn't help!
