The BeginTrans method begins a database transaction. Use of transactions is optional.
Syntax
HRESULT BeginTrans();
Parameters
This method takes no parameters.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Remarks
During a transaction, all changes to the database are deferred until IGuideStore::CommitTrans is called, at which time changes are saved and the transaction ends. You can also end a transaction by calling IGuideStore::RollbackTrans, which cancels any pending changes.
