Hi All,

Just to let you know that I have deleted the download I posted a few months ago, which to allowed you to Zip/Unzip from within VFP using just the built in code of Windows XP. If anyone has downloaded it, please be aware of some licencing issues.

I have received an email today from Glen Horton of InnerMedia. It seems that when MS licenced the Zip bits in XP, it did not include rights for users to use the facilities directly outside of XP. I reproduce his email below.

Makes you wonder what other licences are needed whenever we step out of straight VFP. Does MS publish a list of which bits are freely usable?

Alan

Hello Alan,

I was very surprised to see your inventive approach to using the Windows XP
zip folders facilities from VFP and I want to take this opportunity to let
you know of some legal ramifications related to the approach you have
developed.  

Third-party sub-licensing for using the Windows XP Shell zip folders via
programatic or automated means is not covered by Microsoft's DynaZip
license.  To use DynaZip's facilities and programatic interfaces either
directly or indirectly, a developer must have a valid, legal license to
DynaZip.  Please warn your readers that they will be exposed legally if
they intend to use the Windows XP zip folders facilities via programatic
or automated means without acquiring a license.

If you need additional information regarding DynaZip Licensing, please
contact me.

Thanks,


Glen Horton
