MS Access Forum / General 1 / December 2005Automate WinZip self-extract
Hi all, I regularly use FTP to place Self Extracting Zip files on the web for remote users to update their datafiles. Works very nicely. I have automated the creation of the initial zip file ( update.zip ), and can automate the FTP'ing of the SE zip file to the update site. I have, as yet, been unable to find a way of automating the creation of a SE zip file from the initial update.zip. I have performed a rather exhaustive search and have come up with nothing. Has anyone had experience with this? Thanks in advance. Karl Look here: http://www.access-programmers.co.uk/forums/index.php? and look in the Code Repository for "Zip Files Within Access"  SignaturePC Datasheet Your Resource For Help With Access, Excel And Word Applications resource@pcdatasheet.com www.pcdatasheet.com Over 1000 Access users have come to me for help. My Fees are very reasonable. > Hi all, > [quoted text clipped - 13 lines] > > Karl > Look here: > http://www.access-programmers.co.uk/forums/index.php? > > and look in the Code Repository for "Zip Files Within Access" >[garbage snipped] The CDMA charter prohibits advertising and PC Datasheet is the only consultant that refuses to adhere to that charter. There are literally hundreds of competent Access consultants available, that are ethical. Many post regularly in this newsgroup, others can easily be located by googling or visiting the new braintrade.biz or guru.com. Either Steve's advertising should be stopped or the CDMA charter should be amended to permit it. Permitting Steve to continue his spamming punishes the many scrupulous consultants who contribute here but don't advertise. Hi Steve, Thanks for that. I am unable to find the thread for " Zip Files Within Access " within the Code Repository. I can recall following this same link a few weeks ago - I think it was from a different posting in this group. Any further ideas?

The winzip command line package contains full documentation on command line parameters. You can use the WinZip command line extensions to zip and unzip your file. For example, you can unzip your file to a known location with wzunzip.exe, do whatever with it , and then rezip it by shelling to wzzip.exe: SignaturePC Datasheet Your Resource For Help With Access, Excel And Word Applications resource@pcdatasheet.com www.pcdatasheet.com Over 1000 Access users have come to me for help.

I feel I have a reasonable handle on the creation of zip files within an app thanks to the many helpful individuals in this group. The tricky bit is making that zip file into a self-extracting file from within a code module. You see, the remote users simply download the SE file and run it to update their datafiles. I've tried using plain zip files in the past, but it exposes the ability for them to change unzip paths etc. which caused issues. I'll keep looking, but in the mean time, I'll have another look at the WinZip site in case I've missed something there.

The link is: http://www.winzip.com/prodpagecl.htm I have not used it. James A.

What it really needs is an object model and an automation interface so that Access can control it. zlib.dll is good for having Access compress or uncompress programmatically but I don't think it can handle creating a self-extracting archive. James A. Fortune > Ok is that ironic or what, the idea of WinZip was to get a way > from the command line run PKZip et al and now they bring out > command line support for winzip. Hmm. I don't think that was the justification for WinXip. It was to provide a GUI to something that could be fairly opaque at the command line, even for people like me who are no strangers to the CLI. I use WinZip for unzipping files because it has an Explorer-like UI, which is simply easier than doing it from the command line. Providing a commandline interface just makes WinZip scriptable. I see no contradiction here at all. SignatureDavid W. Fenton http://www.bway.net/~dfenton dfenton at bway dot net http://www.bway.net/~dfassoc So, in other words, you use Winzip to get away from the command line PKZip. What contradiction were you referring to (that you say doesn't exist) ?

No, I use it because it's faster and easier, and provides functionality that is opaque in PKZip. In other words, it's a better program. > What contradiction were you referring to (that you say doesn't > exist) ? There is no contradiction in WinZip adding a commandline interface. They are extending a program to make it scriptable. PKZip was scriptable, but had a UI that few people today can understand. Adding a commandline interface is not being done to serve those people. It's being done to serve the people who would still use PKZip for the scripting. There is no condtradiction here at all. SignatureDavid W. Fenton http://www.bway.net/~dfenton dfenton at bway dot net http://www.bway.net/~dfassoc So you repeat that you use Winzip to get away from the command line PKZip. Oh right, only I didn't say it was a contradiction I said it was ironic. SignatureTerry Kreft >> So, in other words, you use Winzip to get away from the command >> line PKZip.

Ironic indeed. Phil Katz (PKzip) owned the market for years, long before WinZip or even Windows. But they were very slow to put a GUI on it when people began to become accustomed to Windows. That opened the door for WinZip. The WinZip command line tools are not new, however. They have never bundled them with WinZip but have been available for licensed WinZip users for years. The tool that the OP needs has been included with PKzip almost from the beginning. It's called zip2exe. It runs from the command line and simply creates a self extracting zip from a zip file. Note to OP - there are some "freeware" versions of zip2exe floating around. I'm not certain if they are really freeware or zip2exe PKzip rip-offs.

I don't seem to know one account from another. Sorry. Randy Harris OK. I had a thorough look at PKzip and a few others - thanks for the leads. I ended up purchasing a licence for WinZip Self-Extractor 2.2. The help file has a rather handy list of command line options to choose from. Works like a charm. ...........there's a bloke I know in Sydney saying to himself " I told you so ".
