I created OLEcontrol classs of OLEClasses dzocx32.ocx and duzocx32.ocx. I then AddObject() my own classes to the container that has the buttons that do my zipping and unzipping. The first time I tried using the controls, I just placed them on the form, perhaps after subclassing them in this way. But I found that they used up a huge amount of memory, so I just ADDOBJECT() and REMOVEOBJECT() each one as needed.

I still use version 3. I suppose you have version 4 if you just bought it. Perhaps the controls are slimmer.
