Setting ActiveX properties at development time

In Dolphin, is it possible, at *development* time, to instantiate an ActiveX (OCX) object,
set some properties for that object, and store it in a class variable. Then, deploy
an executable that uses that ActiveX object at runtime? I tried this, but got an error
at runtime. I assume that there is some connection established between the
Dolphin object and the ActiveX object that is broken when the image is stripped
and deployed. If this is the problem, is there a way to re-establish that connection
when the executable is started? Thanks.

You'll probably need to serialize the control's state so that it is
restored. If it is a visual object, you can use the AXControlSite to do this
automatically. If it isn't you can use the controls implementation of
IPersistStream to write and restore its state to an IStream.
