Thread: ZIP OCX???

  1. #1
    Guest
    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!!!!!!!!

    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.

    {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/

    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

    Thumbs up John Slade is correct

    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 , and C++ makes really small Exe's as long as there is no MFC)


    Thanks,
    Dennis

    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.

    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.
