1. Integrated Compressionmethods
For the implementation of the ActiveX DLL there have been selected
two compressionmethods. The ZIP component was choosen, because ZIP
is a widespread method and ACE has been selected as a result of
its very high compressionrats. Both compressionmethods can be downloaded
as trial version from the page of the designer of the component.
(ZIP at Bigspeed
Net and ACE at Winace.com).
The ZIP DLL by Bigspeed Net is the fastest and smallest ZIP DLL
on the market. The within the framework of this projects designed
ActiveX DLL offers the programmer the use of the functions provided
by the both archivetypes in a easy way without the need to include
additional code, as it must be done when integrating eighter the
ZIP or ACE DLL alone.
