>I'm trying to patch some old Fox DOS code to run in VFP 6.0 with as few modifications as possible. We're in the middle of design phase for a new system, but want to replace all the old Fox DOS to avoid any Y2K problems. The new system will completely replace what we have now. I don't want to create a form to use the OCX. The old code just did RUN PKUNZIP MyZip.ZIP. We tried just leaving this in, but ran into memory problems.

I just tried to CREATEOBJECT my class based on dzocx32.ocx from the command window. It said something like "OLE Object invalid for this container". You might need to place your zip control on a form. But since the control isn't actually visible, you can ADDOBJECT it to any form that happens to be open when you call it, as long as it's in scope. You might replace your zipping button with a container that has a zipping button and gets dynazip controls ADDOBJECTed to it as needed. That doesn't seem too invasive to me. There's no need to make a new form.
