Zipping files using VB - RESOLVED

[oobern]

I am creating a program to do my archiving on the first day of each month for the previous months data. I am wondering if it is possible using Visual Basic , to zip those files and move them to particular directories, without manually having to do each.
Can someone give me a hand as to where i would start. I am just confused on how to make VB zip a file. What references would i use?, etc. If possible can someone post a code snippet of how this may be done.

Thanks in advance

While there might be better ways, you could use the command shell to call the command-line ZIP utility.

Nice article for you on the topic...

Attached are two examples on how to zip/unzip files. Only 1 module, 1 dll and a small snippet of code for each. Very, very easy to use.

using VB5 no less?

Who me?

No, VB6

[dglienna]

the sample was written in vb5, or at least the module was.

Try using ARJ

dim x 

    x = shell("arj a -va c:\MyArchive.arj c:\Hello.mdb")

What would i use as a reference to use arj????

you don't need a reference if you call it using shell. I haven't used arj for years. i really liked it, back when nobody knew what it was even.

That sample from vbaccelerator (link was provided by NoteMe) is the best solution by far: wrapper dll is utilizing the same libraries that Winzip does and it works like a charm.

zip32.dll is from 1998. the ones with winzip 9.0 are Feb. 2004
I guess those are 16 bit?

[NoteMe]

It would be weird to call a dll for zip32.dll if it is 16bit isn't it? I havn't checked, but that would really be weird.

the bas module says it was written in vb5

Rather than guessing you should try that thing. If I'm saying it works like a charm - means it works like a charm. Period. But what ever ...

EDIT: here is a quick info directly from vbaccelerator.

Provided a new version of the Info-ZIP Zip32.DLL with encryption code compiled in. This enables you to create password-protected ZIP files.

OK, already. I'm up for anything at this point. I swore it'd work after it worked here.

It wasn't seamless, but it did work. Thanks.
