Thanks Cheeso you're are star!
I really appreciate you added the wrapper within your libary. I didn't want to have to create and maintain my own version. I believe it also enhances your library. looking forward to further COM enhancements.
In answer to your question I'm currently using vbscript in WSH and SQL Server Data Transformation Services - I know time to upgrade but life is never that easy
Some things i noticed on 188.8.131.52
the DotNetZipLib-Runtime-v1.9.msi once run is titled 1.8 and installs to 1.8.
Within the chm on the ComHelper documentation the functions ReturnValue is "[Missing <returns> documentation for "......"
perhaps a couple of tweaks for your next release
Thanks again Matt
