zip support?

Hi...

need zip/unzip in Dolphin5. Does anybody know how?

Thanks!

I've used the following Active/X component from VisualAge Smalltalk and it
worked well.  Since Active/X support is better in Dolphin that VA, it bodes
well that it would work nicely for you.

Thank you for the tip, but 300$ is much too much for this project.
Unbelievable, but I did not find any cheap lib yet.
Seems that I have to use Java again :-(.

How about:

http://www.gzip.org/zlib/

I know open source zip wrappers have been discussed on Smalltalk news groups
in the past.

Well, Ant (http://jakarta.apache.org/ant) has built-in zip support, and it's
easy enough to set it up to call it from a batch file, and it's easy enough to
call a batch file from Dolphin, and that doesn't cost anything but your time,
so...

A lo-tech solution (if you have a WinZip licence) is to directly run
winzip32.exe with command-line parameters. I've done this for a couple of
one-off jobs and it works quite well. Details:

http://www.winzip.com/xcmdline.htm

I also looked briefly at converting Squeak's compression features, but it
was too much for what I needed to do at the time.

Thanks for all your input, but is is not so easy in this case. What I get is
a zip-compressed database field that I have to uncompress, so any library or
app for zip files does not help me (including zlib).

BTW: I use ant myself and enjoy it very much ;-).

Jochen,

Have look at Bill Schwab's Dolphin Goodies which include a ZLib package.
It is available at his website:

If [de]compressing strings or byte arrays is the goal, then the ZLib package
will work as-is, but I've never actually tackled the .zip file problem.
Squeak has a solution though, and it might be possible to shamelessly hack
the missing pieces into Dolphin.  Also, the ZLib site mentions "minizip"
contained in the ZLib distribution as offering a way to read Zip files.

BTW, do not hit www . zlib . com (spread out for your protection<g>) unless
you like endless streams of pop-up ads.  The ZLib site is
http://www.gzip.org/zlib/ also reachable via www.zlib.org.

Have a good one,

Bill

I have written a somewhat working wrapper for BigSpeedZip.DLL
(http://www.bigspeedsoft.com/bszipdll/bszipdll.html) for DSP 4. I can send
you the code if you are interested. If I remember right they have an eval
version wich "just" limits the file size.
