PostInitHook() will automatically fire when the business object is instanciated. PreRequeryHook() is automatically called when doing a Requery().

I always populate my view parameters in the PostInitHook(), and use properties on the business object. For example, if I had a view (and it was the primary view for this business object) that returned a single record via the vp_field parameter, I would create a property on the business object called "iField". Then I would add code to the PostInitHook that looked like:

This.AddViewParameter("vp_field", "This.iField")

Once I've dropped this on a form, I would bind the control to this property. Anytime a Requery() occurs, the business object will automatically populate the vp_field parameter based on the iField property. The nice thing about doing things this way is it maximizes reuse. I can use the same business object, without modification, for a desktop app or a web app.

I don't use the cViewParameter property on the controls, so I'm not really familar with how they work. Maybe someone else will jump in.
