hi, i have another question,
how can i let my program unpack a file in its directory
(for installing purposes).
It should be able to unpack a .zip-file with any shell or external program. I know there is something called "info-zip", that is a free un/pack-module for C/C++ but i don't think it is available for VB. I dont want my program to use a shell like "pkunzip.exe" or that it runs winzip because if a user does not have it it will hardly work.

(if you know how to do a shell on a .dll file for ANY format(.rar, .arj, .ace, whatever) and have on i would be pleased if you could tell me where to get it.

thank you very much
