ZIP OCX???

Does anyone know where I can get (if possible) a FREE ZIP control? (I use Polar ZIP and it works great but the $200 I don't want to spend).

try searching on
http://www.planet-source-code.com
Hell, you may learn how to do it Without an OCX,

and I dont think the company who makes the OCX you use should charge $200
winzip only costs $30!!!!!!!!

unfortunately.
Thanks for the Link.

WOW,
I searched for almost a half an hour and found nothing on PSC for zip files.

You could use pkzip25.exe, which I believe it is free. Just use the Shell function to fit your needs.

Code:

---

Usage:  PKZIP [command] [options] zipfile [@list] files
'View .ZIP file Contents
Shell "PKZIP zipfile", vbNormalFocus
'Create ZIP file
Shell "PKZIP -add zipfile [files]", vbNormalFocus
'Extract Zip File
Shell "PKZIP -extract zipfile", vbNormalFocus

---

If you don't have PKZIP25.exe, I will send it to you.

Sure, I'll take it!

but I would also like to know how to do it with code. C++ OR VB will do....(this isnt just for matthew, this is for anyone who can answer my Q)

{you need some DLL's though)

Thanks, I'll give it a try, but using a DLL Kind of defeats the purpose of Not-Using an OCX/

There is some info about how to do ZIP compression in VB over at vbaccelerator:-

The code at VBAccelerator.com just uses a dll by InfoZip. It's very hard to do zip compression in vb. But I keep saying it: You can get the specs of Zip and almost any other file format on http://wotsit.org

Check out: ftp://ftp.freesoftware.com/pub/infozip/zlib/

One edit later...sorry...wrong url...

The zip and unzip components available at http://www.vbaccelerator.com are the ones used in winzip et al. We have been mucking around with them for two or three months and have almost got them working in a vb product, (still trying to get unzip upgrade from a web address working), they work fine.

Also you can get the source code to a project which uses them on this site.:)

Go to accelerator, download the controls, and build your own compression/decompression interfaces. I know you are the type of guy who loves putting your own controls together.

cool, I'll have to check it out,

but does anybody know how to do this in C++ and/or delphi?
without the control(s)?

because I want to write a kick-ass runtime-free Zip/UnZip utility, and I really like C++ and Delphi, Awesome languages :)

so I would prefer it in that (Reason, VB has runtimes, and if you include them with it with Fusion the Exe's are Huge, Delphi makes fairly large executables, but there are no runtimes :D, and C++ makes really small Exe's as long as there is no MFC)


Thanks,

I'm using CGZipLibrary by Chris Eastwood in my app right now. It's just a few Dlls that do the work for you. Just copy his example and download the files and you're all set.

Check out the ZLib site - it has full source for compressing/decompressing files. Also look at GNU tar.

Here is a free ActiveX Control called ActiveZipper OCX - for zipping files.

Can't seem to find ActiveZipper at the URL you posted.. I even tried a search on that site, but no ActiveZipper..

Where can I find this?

Maybe they decided to not make it free :(.
I don't even have a copy of it anymore.
Perhaps you could try searching a search engine.
That's all the advice I can give, I'm not really very sure where to find it.
