| Ends a transaction for multiple imports. |
| |
|
void EndTransactionalImport (
VARIANT_BOOL bSuccess
) |
|
| |
| Parameters | | bSuccess | | [in] True if you want to commit all changes made during the transaction, false for rolling back those changes. | | | | Remarks |
 | The value for the parameter bSuccess must not depend on the return values of the import routines that were called
during the transaction. If one of the imports fails, the changes made to the files are rolled back independently of the
value of the parameter bSuccess.
This parameter can be used if you want to rollback the changes for a reason outside the import routines. |
| When the transaction is committed either all imports are executed or none of them is. ('all or nothing') |
| It is important to keep the period between starting and ending the transactional import as short as possible. During
this transaction none of the files involved can be modified by other users. It is therefore adviseable to not show any
user interface during the transactional import. |
| This method can be only be used for objects of the same dossier! |
| None of the imported items will be available in the files as long as the transactional import is busy. It is only after
the transaction is completed that all (or none) of the items are visible in the files. |
