Auto Create Zip File 1

[HumbleSeeker]

I'm currently building a small little toy, it logs which files have been updated in a directory and copies them to an archiving directory. The code is simple and works, I now want to take it to the next level of automatically zipping up the archive files and sub-directories.

Does anyone know of code in Visual Basic .Net that will perform the zip, or a free simple DLL I can include into the project. So far all I've found is DLL for $300, which as this is a play thing of mine I don't want to spend yet.

Any suggestions?

Check out

You can download a version for 30 day evaluation. You will be unlikely to find a free version of a .NET zip utility.

Thanks for the reply, but I really want my little toy to work for a couple of months, while I continue to modify and expand it.

OK if there isn't a free DLL available, does anyone know where I can get information and/or source code to create a zip file myself? Or even better has found a free DLL?

Did you think of WinZip command line support? You can either create batch file that will zip all files in archive folder an you can start the batch process from your app,
Or even better you can call commands from code using Shell.

There is a GPL zip utility for .NET available at

http://www.icsharpcode.com/OpenSource/SharpZipLib/Default.aspx

which should work in VB.NET. Download the compiled assembly and reference it in your application.

Thanks for that link octothorpe, it worked a treat. I found code to use the DLL at:

It does the job. Thanks to all who have helped.
