IObjectContext::SetAbort method

Declares that the transaction in which the object is executing must be aborted and that the object should be deactivated when it returns from the currently executing method call.

Syntax


HRESULT SetAbort();

Parameters

This method has no parameters.

Return value

This method can return the following values.

Return codeDescription
S_OK

The method completed successfully.

E_UNEXPECTED

An unexpected error occurred. This can happen if one object passes its IObjectContext pointer to another object and the other object calls SetAbort using this pointer. An IObjectContext pointer is not valid outside the context of the object that originally obtained it.

 

Remarks

The object is deactivated automatically on return from the method in which it called SetAbort. If the object is the root of an automatic transaction, COM+ aborts the transaction. If the object is transactional but not the root of an automatic transaction, the transaction in which it's participating is doomed to abort.

You can call SetAbort in error handlers to ensure that a transaction aborts when an error occurs. You can also call SetAbort at the beginning of a method to prevent your object from committing prematurely in the event of an unexpected return and then, if all goes well, call SetComplete just before the method returns.
