Returns a MAPIERROR structure that contains information about the previous error generated by the form manager object.
HRESULT GetLastError(
HRESULT hResult,
ULONG ulFlags,
LPMAPIERROR FAR * lppMAPIError
);
Parameters
hResult
[in] An HRESULT data type that contains the error value generated in the previous method call.ulFlags
[in] A bitmask of flags that controls the type of strings returned. 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.
- MAPI_UNICODE
lppMAPIError
[out] A pointer to a pointer to the returned MAPIERROR structure that contains version, component, and context information for the error. This parameter can be set to NULL if there is no MAPIERROR structure to return.
Return Value
S_OK
The call succeeded and has returned the expected value or values.MAPI_E_BAD_CHARWIDTH
Either the MAPI_UNICODE flag was set and GetLastError does not support Unicode, or MAPI_UNICODE was not set and GetLastError supports only Unicode.
Remarks
The IMAPIFormMgr::GetLastError method supplies information about a prior method call that failed. Callers can provide their users with detailed information about the error by including the data from the MAPIERROR structure in a dialog box.
Notes to Callers
You can use 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, NULL is returned in lppMAPIError instead.
