Thanks, it is very useful class, they have alot of operations for winzip but still lacking if error happened in zipping the files (like the file is open by another user), so I am still looking for a solution for my problem.

>>I am using WZZIP from WinZip to archive some files, I need to get a return error if for any reason the process failed, any help ?
