2492.0. "a "router" OCX" by IMPERO::GORRINO (Sagrinte nen) Fri Feb 07 1997 08:48

	I'm evaluating the possibility of implementing an OCX like that:

	- It receives an input from an external application. It examines the
	  input and, driven by its configuration, evaluates a value to
	  be assigned to a property of another visible control

	- event handling callbacks associated to th emodification of other
	  controls properties modify an OCX property. The OCX callback
	  evaluates a value to be sent to the external application.


	In other words, this OCX acts as an intelligent  router between the 
	external application and the VB application controls, by encapsulating
	all the operations to be performed when associating application
	data to control properties.

	Is this feasable? are there any examples around to look at?

    Interesting. Presumably you're making it an OCX because you want to
    implement it in C++? I'd be tempted if I could to implement it as an
    in-process OLE server with time-critical bits written in C.
