i use the sharpziblib library for zipping purposes ( not yet needed in VS
2005 ) but i guess it is just a mather of a recompile

Reidar,

There is a sample in the 101 samples for VB2005 (Compresion)

Which makes that it is only copy and paste

http://msdn.microsoft.com/vstudio/downloads/101samples/default.aspx

I hope this helps,

Check out the 'System.IO.Compression.GzipStream' class.

Herfried,
I have not used GzipStream yet, however I get the impression that it only
compresses a single stream (file) rather then maintain the collection of
files in a zip. Of course I could have the wrong impression of GzipStream

I understand that you need to use some upcoming WinFX API to maintain the
collection of files in a zip.

For example you could use GzipStream to compress WebRequests & WebResponses
"on the fly".

That might be true, but the OP was specifically asking for zipping a single
file ;-).

Herfried,

Does the OP want a file that uses the ZIP compression algorithm, or does he
want a .ZIP file that contains a single file?

I really don't know. When I hear "zip a file" I think of a .ZIP file that
contains a single file. Not a file that uses the ZIP compression algorithm.

what I needed except for I also need to password protect the copmressed file.
