IMsgServiceAdmin::GetLastError

The IMsgServiceAdmin::GetLastError method returns a MAPIERROR structure containing information about the last error that occurred for a message service administration object.

Quick Info

See IMsgServiceAdmin : IUnknown.

HRESULT GetLastError(
  HRESULT hResult,                
  ULONG ulFlags,                  
  LPMAPIERROR FAR * lppMAPIError  
);

Parameters

hResult

[in] HRESULT data type containing the error value generated by the previous method call.

ulFlags

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

MAPI_UNICODE: 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.

lppMAPIError

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

Return Values

S_OK: The call succeeded and has returned the expected value or values.
MAPI_E_BAD_CHARWIDTH: The MAPI_UNICODE flag was set and the message service administration object does not support Unicode.

Remarks

The IMsgServiceAdmin::GetLastError method retrieves information about the last error that was returned by an IMsgServiceAdmin method call. Clients can provide their users with detailed information about the error by including this information in a dialog box.

Notes to Callers

You can make use of the MAPIERROR structure pointed to by the lppMAPIError parameter, if MAPI supplies one, 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, GetLastError returns a pointer to NULL in lppMAPIError instead.
