Returns a MAPIERROR structure that contains information about the previous error that occurred to a profile administration object.

HRESULT GetLastError(
  HRESULT hResult,
  ULONG ulFlags,


[in] An HRESULT data type that contains the error value generated in the previous method call.


[in] A bitmask of flags that controls the type of strings returned. The following flag can be set:


The strings in the MAPIERROR structure returned in the lppMAPIError parameter are in Unicode format. If the MAPI_UNICODE flag is not set, the strings are in ANSI format.


[out] A pointer to a pointer to the MAPIERROR structure that contains version, component, and context information for the error. The lppMAPIError parameter can be set to NULL if there is no MAPIERROR structure to return.


The call succeeded and has returned the expected value or values.


Either the MAPI_UNICODE flag was set and the implementation does not support Unicode, or MAPI_UNICODE was not set and the implementation supports only Unicode.

The IProfAdmin::GetLastError method retrieves information about the last error returned from a method call for the profile administration object.

You can use the MAPIERROR structure, if MAPI supplies one, pointed to by the lppMAPIError parameter only if GetLastError returns S_OK. Sometimes MAPI cannot determine what the last error was or has nothing more to report about the error. In this situation, a pointer to NULL is returned in lppMAPIError.

To release all the memory allocated by MAPI for the MAPIERROR structure, call the MAPIFreeBuffer function.
