IErrorLookup::GetErrorDescription

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

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

• 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.

• 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.
