UnZipping on the Fly

[Richard Stevens]

Kevin:

I'm storing zip files in a Blob database fields. What I would like to do is to UnZip a file using your Delphi component on the fly. i.e. without having to save the zip file to disk first. Is this possible??

Sorry, I just found the ArchiveStream property...

Just to be sure it's clear, stream zipping/unzipping is done using one or a combination of the following...

1) UnZipToStream method to unzip from an archive into your stream.
2) ZipFromStream method zips from your stream into the archive.
3) The ArchiveStream Property is used to hold the archive in memory.

If you use #1 and/or #2 above in combination with #3 then you are using stream<-->stream zipping/unzipping.

I thought I had written this post earlier but I don't see it showing up, so, sorry if it ends up being a repost.
