IErrorLookup::GetErrorDescription

  • Artikel

Returns the error message and source, based on the return code and the provider-specific error number.

Syntax

HRESULT GetErrorDescription (
   HRESULT        hrError,
   DWORD          dwLookupID,
   DISPPARAMS    *pdispparams,
   LCID           lcid,
   BSTR          *pbstrSource,
   BSTR          *pbstrDescription);

Parameters

  • hrError
    [in] The code returned by the method that caused the error.

  • dwLookupID
    [in] The provider-specific number of the error.

  • pdispparams
    [in] The parameters of the error.

  • lcid
    [in] The locale ID for which to return the description and source.

  • pbstrSource
    [out] A pointer to memory in which to return a pointer to the name of the component that generated the error. If an error occurs, *pbstrSource is set to a null pointer. The memory for this string is allocated by the provider and must be freed by the consumer with a call to SysFreeString.

  • pbstrDescription
    [out] A pointer to memory in which to return a pointer to a string that describes the error. If pdispparams was not a null pointer, the error parameters are integrated into this description. If there is no error description or an error occurs, the returned value (*pbstrDescription) is a null pointer. The memory for this string is allocated by the provider and must be freed by the consumer with a call to SysFreeString.

Return Code

  • S_OK
    The method succeeded.

  • E_FAIL
    A provider-specific error occurred.

  • E_INVALIDARG
    pbstrSource or pbstrDescription was a null pointer.

  • E_OUTOFMEMORY
    The provider was unable to allocate sufficient memory in which to return the error source or description.

  • DB_E_BADHRESULT
    hrError was invalid.

  • DB_E_BADLOOKUPID
    dwLookupID was invalid.

  • DB_E_NOLOCALE
    The locale ID specified in lcid was not supported by the provider.
