Description:
The Cancel method cancels an outstanding asynchronous Send or RegisterNotification call.
Note: To cancel a RegisterNotification call, use CancelNotification instead,
as it provides a more convenient way of doing this.
This is a synchronous method.
Syntax:
result = so.IMessaging.Cancel(criteria);
Arguments:
criteria:
This is an object with the TransactionID property
(number). criteria.TransactionID specifies the transaction
ID of the Send or RegisterNotification call
to cancel. The transaction ID is the result.TransactionID value
that was returned as part of the result of the initial call.
Return value:
The Cancel method returns an object that contains
an error code and an error message.
