@gnozal
Do you think there is a way to add multivolume-support?
Or, if not, do you have any idea to handle it by code?

I simply use the ZLIB available functions, and AFAIK there is no function to handle multivolume archives.

It's a pity. Thanks for your reply!

Hi gnozal,

how I can check if an archive requires a password?

I make a small code like this.:

Code: Select all

x=PureZIP_FindFile(ZipFileName$(CurrentWindow),b$,#True)
PureZIP_GetFileInfo(ZipFileName$(CurrentWindow), x, @FileInfo.PureZIP_FileInfo)
; Passwort abfrage.
If FileInfo\flag = 9
  pw$=InputRequester(Lang$(235), Lang$(236), "")
  If pw$<>""
    PureZIP_SetArchivePassword(pw$)
  EndIf
EndIf

Is that the correct way to do ?

No, the help says :

Bit 0: If set, indicates that the file is encrypted.

So it should be something like that :

Code: Select all

If FileInfo\flag & %1 
 IsCrypted = #True 
Else 
 IsCrypted = #False 
EndIf

Ok, Thanks for your help.

Hello gnozal!

I want to re-direct a bug to you that was found by "String" from the german PB forum.

He says that if he creates an archive with PureZIP and its filename contains sspeacial characters like äöüÄÖÜß, then this archiv is not caompatible with other pack-programs (WinRAR, 7-Zip) anymore.

Please, contact him for furthher informations, link to the german thread:

Hallo gnozal

Beim entpacken entstehen aber Fehler.

Hello gnozal
PureZIP can pack long paths.
However, faults arise unpack.

No time to debug right now.
However, could you test http://freenet-homepage.de/gnozal/PureZIP_BETA.zip ? I changed one constant value ...

Posted: **Tue Jun 12, 2007 10:40 am**

Das Problem existiert auch bei der BETA.zip
PureZIP kann einen Pfad mit 254 Zeichen packen.
Aber nur eine Pfad Länge von 108 entpacken.

The problem exists also at the BETA.zip
PureZIP can pack a path with 254 signs.
But only one unpacking path length of 108.

Total path length is 243 for unpacked file Error_7777.jpg

So it seems to work here ?

I want to take a closer look on this lib. But I can not find any information if this lib is thread save and unicode able. Anything on this!?

The PB3.94 library is not threadsafe nor unicode compatible.

The PB4.0x library exists in 4 versions :
- the standard version, located in %Purebasic%\PureLibraries\UserLibraries\ ;
- the thread-safe version, located in %Purebasic%\SubSystems\UserLibThreadSafe\PureLibraries\ .
- the unicode version, located in %Purebasic%\SubSystems\UserLibUnicode\PureLibraries\ .
- the unicode + thread-safe version, located in %Purebasic%\SubSystems\UserLibunicodeThreadSafe\PureLibraries\ .

In order to use this library in thread-safe mode (compiler option /THREAD), you have to enable the subsystem 'UserLibThreadSafe'
in the PB IDE, or add '/SUBSYSTEM UserLibThreadSafe' to the PBCompiler arguments. In jaPBe, do nothing : it will automatically
enable the 'UserLibThreadSafe' subsystem to use the threadsafe versions of the installed userlibraries.
It's the same logic for unicode and unicode + thread-safe modes.

I personally only use the standard version ; I did'nt get any feedback for the other versions, so I assume they work.

Oh, thanks for very fast answering. I will try and give any report on success/ failure.

Hopefully I assume right: One open Archive can be handled by one thread or? couse Closing an Archive does not require an archive-handle nor ID.
