I would have to compress all files within a specific folder. Does anyone know how I can do this from within Navision C/SIDE. May be there is some kind of OCX or Automation Server I can use. I thought of using pkzip in a SHELL-command, but isn't there a better solution?

Have a look at zlib http://www.gzip.org/zlib/
A DLL of this compression library can be found at http://www.winimage.com/zLibDll/

I did not try this, but maybe you can call this DLL from C/AL code.

Probably this is a stupid question, but I do not seem to succeed in registring the dll with regsvr32. I get the message "zlib.dll was loaded, but the DllRegisterServer entry point was not found."

Can you help me with this?

I searched a while and found this page http://www.dogma.net/markn/FAQ.html#Q27 where you can download zlibocx2.dll. This file can be registered using regsvr32.

Some C/AL code:



where x is a OCX-variabele, pointing to "zlibIF Class".

Thanks for your time!

I was looking too for some OCX-possibilities, and one I found:http://www.freedownloadscenter.com/Programming/Visual_Basic_Components_H-P/Maquisistem_Zip_Compress_OCX.html. Now, this always shows a Pop-up, and it didn't seem to work properly (I always got an error 'bad file name' or something).

Now, I'm trying your possibility, but here, it seems that I only can compress 1 file to 1 zip-file. Now, my main intention was compressing a folder to one file (because, later on, I have to e-mail this file).

A solution COULD be the following:


Now, this has as major disadvantage that it is a DOS-routine, which means, that it can't use the long Windows-names. E.g. "Waldos zip file.html" becomes something like "waldos~1.HTM". Also the zip-file itself can't have a long file-name. So, if possible, I would prefer another solution.

What version of pkzip are you using? Version 4.00 DOES support long filenames.

Indeed, I was using 2.50.
I found a better pkzip now at http://burks.brighton.ac.uk/burks/software/compress/install.sw?3.cutezip2.exe. It's not pkzip, but pkzipc and works slightly different. Here is my code:


Thanks for the help!

Hi! I'm using the Zip Compress OCX from Binarywork in version 3.0.98. Works fine.

These posts are from 3 years ago ... are there new (free) possibilities to ZIP files from Navision?

You can use "Microsoft Shell Controls And Automation" to zip an entire folder. Parse FolderItems for specified files.



You can find 'Microsoft Shell Controls And Automation' in all Microsoft Windows computer from W95.

Previous way of compressing file is pretty good and simple. But You must take care that compressed folders are supported only in XP/2003 Windows versions. For 98/ME/2000 You need to register additional DLL's which could be taken from MS udpate site (searching here)
After this, copy files from downloaded file: zipfldr.dll,dunzip32.dll and dzip32.dll into Windows\System or Windows\System32 (depends on OS) directory and register zipfldr.dll with regserv:
regserv32 X:\windows\system32\zipfldr.dll
Should work:)
Thanks for the way described.
Maybe somebody tried using CAB?:)

Hi

When testing Albertos code example above I'm getting an error: "An exception occurred from an external component."

What am I doing wrong?

Specifically the error occours when executing the "DstFolder:=Shell32.NameSpace(ZipFileName);" statement - I'm guessing because ZipFileName points to a file and not a folder?



Besides this I'd like to know which modifications I have to make in the code in order to be able to compress (and de-compress) single files?

Thanks in advance!

Which version of OS are u using? Is ZIP Folders functionality enabled?
About working with seperate files, it's the same as working with standart folders. F.e. you can define Folder.CopyHere(filename) and so on.

Thanks for your reply.

I'm on WinXP.
I don't know if ZIP folders functionality is enabled or disabled - is this configurable? I was hoping to write code that would be executable on any WinXP machine.

If I understand you correct,

is legal?
