Failed to QueryInterface(COM) IInplacePrintPreview of Excel 2016 RRS feed

  • Question

  • I wanna show printpreivew dialog in my application. The following code works with older version Excel but failed with Excel 2016, and returned error is 0x80040155 (Interface not registered)

    LPOLEOBJECT lpObject;

    IInplacePrintPreview pPrintPrieviw;

    HRESULT hr = lpObject->QueryInterface(IID_IInplacePrintPreview, reinterpret_cast<void**>(&pPrintPrieviw));

    So does Excel 2016 not support this interface or any alternative interface is available?

  • Hi Michael,

    To use the PrintPriview function via C++, you can refer the code below:

    void printPreviewExcel()
    	// Translate server ProgID into a CLSID. ClsidFromProgID
    	// gets this information from the registry.
    	CLSID clsid;
    	CLSIDFromProgID(L"Excel.Application", &clsid);
    	CoInitialize(nullptr); // NULL if using older VC++
    						   // Get an interface to the running instance, if any..
    	IUnknown *pUnk;
    	HRESULT hr = GetActiveObject(clsid, NULL, (IUnknown**)&pUnk);
    	// Get IDispatch interface for Automation...
    	IDispatch *pDisp;
    	hr = pUnk->QueryInterface(IID_IDispatch, (void **)&pDisp);
    	//get active presentation 
    	DISPID dispID;
    	LPOLESTR lpDesc = (LPOLESTR)L"ActiveWorkbook";
    	hr = pDisp->GetIDsOfNames(IID_NULL, &lpDesc, 1, LOCALE_USER_DEFAULT, &dispID);
    	VARIANT *pVarResult = new VARIANT();
    	DISPPARAMS *dispparams = new DISPPARAMS();
    	pDisp->Invoke(dispID, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_PROPERTYGET, dispparams, pVarResult, NULL, NULL);
    	//call PrintPreview
    	lpDesc = (LPOLESTR)L"PrintPreview";
    	hr = pVarResult->pdispVal->GetIDsOfNames(IID_NULL, &lpDesc, 1, LOCALE_USER_DEFAULT, &dispID);
    	hr = pVarResult->pdispVal->Invoke(dispID, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, dispparams, pVarResult, NULL, NULL);
    	// Release the no-longer-needed IUnknown...
    Regards & Fei
