D.2.7 Condition Refresh ToC Previous Next

The COM A&E Wrapper does not store the state of Conditions. When ConditionRefresh is called the Refresh Method is called on all COM AE Subscriptions associated with the ConditionRefresh call. The wrapper needs to wait until it receives the call back with the bLastRefresh flag set to True in the OnEvent call before it can tell the UA Client that the Refresh has completed.
