DISPPARAMS dp = { NULL, NULL, 0, 0 }; DISPID dispID; LPOLESTR szDoc = L"Documents"; IDispatch* pDocuments = NULL; VARIANT varRetVal; hr = m_pDispApp->GetIDsOfNames(IID_NULL, &szDoc, 1, LOCALE_SYSTEM_DEFAULT, &dispID); hr = m_pDispApp->Invoke(dispID, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYGET, &dp, &varRetVal, NULL, NULL); if (!SUCCEEDED(hr)) { Destroy(); return -1; } // keep the Dispatch pointer in the member variable for later use. m_pDocuments = varRetVal.pdispVal; return 0; } int CAutoWord::SaveDocument() { VARIANT varRetVal; EXCEPINFO excepInfo; VARIANTARG varg; varg.vt = VT_BSTR; varg.bstrVal = _bstr_t("c:\\doc1.doc"); // this is the MS-word document filename, must be changed to a valid filename that exists on disk DISPPARAMS dpSave = { &varg, NULL, 1, 0 }; DISPID dispSaveID; LPOLESTR szSaveDoc = L"Save"; HRESULT hr = m_pDocuments->GetIDsOfNames(IID_NULL, &szSaveDoc, 1, LOCALE_SYSTEM_DEFAULT, &dispSaveID); hr = m_pDocuments->Invoke(dispSaveID, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD, &dpSave, &varRetVal, &excepInfo, NULL); printf("hello2\n"); if (FAILED(hr)) { OutputDebugString("The document could not be printed\n"); Destroy(); return -1; } }
