Creating Zip Files
Is there access in VB2005 that allows creation of compressed (Zip) files, or at least has access to the windows-based utility that puts files into a compressed folder?
There is a new System.IO.Compression.GZipStream that handles zipped streams, however this does not handle zip files and entries so you will have to write your own code around it.
I have used the SharpZipLib that James suggested and it works well.
