IWbemStatusCodeText::GetFacilityCodeText method (wbemcli.h)

The IWbemStatusCodeText::GetFacilityCodeText method returns the name of the subsystem where the error occurred, such as "Windows", "WBEM", "SSPI", or "RPC".

Syntax

HRESULT GetFacilityCodeText(
  [in]  HRESULT hRes,
  [in]  LCID    LocaleId,
  [in]  long    lFlags,
  [out] BSTR    *MessageText
);

Parameters

[in] hRes

Handle to the error code for which you want a description.

[in] LocaleId

[out] MessageText

Examples

The following example describes how to use GetFacilityCodeText.

IWbemStatusCodeText * pStatus = NULL;

    SCODE sc = CoCreateInstance(CLSID_WbemStatusCodeText, 
                                    0, CLSCTX_INPROC_SERVER,
                                    IID_IWbemStatusCodeText,
                                    (LPVOID *) &pStatus);
    
    if(sc == S_OK)
    {
        BSTR bstr = 0;

        // The m_hres is an HRESULT variable that has already
        // been declared and initialized.
        sc = pStatus->GetErrorCodeText(m_hres, 0, 0, &bstr);
        if(sc == S_OK)
        {
            // ...display string here.
            SysFreeString(bstr);
            bstr = 0;
        }
        sc = pStatus->GetFacilityCodeText(m_hres, 0, 0, &bstr);
        if(sc == S_OK)
        {
            // to do, display this.
            SysFreeString(bstr);
            bstr = 0;
        }
        pStatus->Release();
    }

    // clean up.
    pStatus->Release();
