Zip plugin

[star2]

I really needed to have compression Option

thanks

OK,

Just tried this too, Copied _ZipPlugin.au3 to the correct directory, (include\user), have the dll in the script directory that I'm creating, compile my script and get error _ZipCreate unknown function, I opened the _ZipPlugin.au3 and it doesn't contain a function called _ZipCreate. it looks like the functions have been deleted from the file.

Can you post your script? _ZipCreate is in the plugin dll, not the .au3 file.

It could not find the correct place to change the compression ratio. I ran several tests and none of them seemed to change the ratio any (even trying no compression).

this should work correct?

I've made a couple of updates, please see first post for links and edits.

I must be missing something. I have tried every examble and read through everything in the downloaded zip, and I still cannot get it to create a zip file and add a file to it. I can get unzip to work but that is it. Could you give an example on how to create a zip file and then add a file to the zip file. thanks.

The files in the Au3Zip has a documented example.

I'm not at my devel machine so I can't look at it right now but I should get a chance within the next hour or so.

[Icarii]

Ok, I found the example (hey, it's monday) and got a test to work.

Great stuff, THANKS

One more question. Is there a list of the possible return values some where? I am adding logging to my script that information would help. Thanks

I found a problem , fixed it and up loaded an new updated version. I called a zip check on the folder being added. So, the func would fail to add the folder.

The return codes from zip.h

// These are the result codes:
#define ZR_OK        0x00000000  // nb. the pseudo-code zr-recent is never returned,
#define ZR_RECENT    0x00000001  // but can be passed to FormatZipMessage.

Thanks for the fast reply. I notice the output that Autoit get is in decimal and the outputs you post are in hex. So I converted them and wrote a function to call to make logging easier. I am sure you have an easier way (I am not the greatest programer). It seems to work but I only test a view of the errors.

Just thought I would share in case it helps someone else. Again thanks for the help.

There is a builtin function to give you the return code's associated message:

_ZipFormatMessage ($return_code)

Is it not working for you??

Edit: Yours are a bit more descriptive.

Well, I did not see that. Bet that could of saved me some time. Oh, well. My script seems to be working, but I am still testing. Thanks for the response.

How do I install this plugin?

Put the dll in a folder where your script will find it. If your distributing you script, you could put it in the script dir.

There is an include file, _ZipPlugin.au3 add this to your project.

Edit: The include file has compiler directive to prevent the compiler from not recognizing the plugin function names, and it provides a couple of methods to assist using the plugin.

There is an example program called PluginZip.au3 that shows the use of plugin.

eltorro, great UDF. As always, you do great work.

Any chance that CodeProject has 7zip functions available?

I haven't checked lately, but not last time I checked , no 7zip.

I suppose it would be possible to wrap the commandline version into a dll. Maybe I wll look into this in the future.

First of all thanks, works great.

I noticed when adding a directory to a zip, that there is very heavy CPU load just prior to actually starting the zip process. The durration of this load increases with the size of and/or number of files in directory being added. It seems that while it is in this state there is no pausing it either i.e. throwing a sleep into and adlib call. Is there away to reduce the CPU load durring that time.

Mike

The plugin code is using a recursive dir search to get the file names, so I would expect some loading. How many files are you talking about? It's probably possible to throw some sleep into the function without to much effort. As for pausing the action, right now it is not possible as there is not any mouse or keyboard support in the plugin. I'll look into adding some kind of handler.
