>I'm at the Gzip web site now(http://www.gzip.org/zlib/), it provides some .h source code in C++ format and .OCX libraries which it says is for win98/NT. But can I import any OCX into VFP to use?

Hi Jimi,

Basically, the ActiveX is a control that you can place on your form or Web. DLL is a library with functions that you can use if you include it to your application. To answer if the OCX works in VFP you should just try it, as most of them do not have any info on that if it works properly with VFP.
