Some OCXes need to have a strict time domain control, as an example those related to communication. As of 9.6 they can\'t be applied in a component because the time domain is (too) heavily under Uniface control. The only current way to use them is to wrap them into a VB6 piece of software but availability of VB6 is under question for next future.
A Uniface application must deal with a ZigBee network over TCP or UDP. Incapsulating the Winsock OCX to collect informations from the network could be done only with a (deprecate) piece of software.
