[endo]

wow, u r fast! I'm waiting thx

... should be fixed (same link).

it works! thanks a lot.

PB4.30, using your latest release posted above.

Seam to have some problems with the callbacks, there generating;

[06:36:56] Waiting for executable to start...
[07:36:56] Executable type: Windows - x86 (32bit)
[07:36:56] Executable started.
[07:36:56] [ERROR] purezipcallback.pb (Line: 26)
[07:36:56] [ERROR] Invalid memory access. (read error at address 2139095084)

And when I try thread safe it does this;

[06:37:21] The Program was killed.
[06:37:22] [COMPILER] Linker error!

POLINK: error: Unresolved external symbol '_PB_StringBasePosition'.
POLINK: Fatal error: 1 unresolved external(s).

Could you post some code ?

POLINK: error: Unresolved external symbol '_PB_StringBasePosition'.
POLINK: Fatal error: 1 unresolved external(s).

Looks like a subsystem issue [did you enable SubSystems\UserLibThreadSafe ?].
The following example works in both standard and threadsafe modes.

Code: Select all

Procedure CB_COMP(FileName.s, Progression.f, Param.l)
  Debug FileName + ", " + StrF(Progression, 0) + ", " + Str(Param)
EndProcedure

PureZIP_SetCompressionCallback(@CB_COMP())

If PureZIP_Archive_Create("C:\purebasic430\program\test.zip", #APPEND_STATUS_CREATE)
  PureZIP_Archive_Compress(#PB_Compiler_Home + "Examples\Sources\2DDrawing.pb", #True, 1)
  PureZIP_Archive_Compress(#PB_Compiler_Home + "Examples\Sources\Arithmetic.pb", #True, 2)
  PureZIP_Archive_Compress(#PB_Compiler_Home + "Examples\Sources\AsmInline.pb", #True, 3)
  PureZIP_Archive_Close()
EndIf

No need your fragment of code showed the error in my callbacks, something must have changed somewhere, I used to use;

PureZIP_CallbackC(File.s,PerCent.f)

with a "While WindowEvent() : Wend" in the callback, removing that and changing the procedure arguments too;

PureZIP_CallbackC(File.s,PerCent.f,Param.l)

Fixed the problem.

No I just enabled "Create threadsafe executable" from the compiler options.

Yes, the callback format changed in the latest download [additional UserParam]. See Tranquil's request.

No I just enabled "Create threadsafe executable" from the compiler options.

Sorry, you need to enable the UserLibThreadSafe subsystem.

Right'o np. thanks.

Does this lib also encompass the zip CRC capabilities?

I don't know exactly what you mean ?
The ZIP files created with this library have a valid Crc32 stored, including crypted archives. This can be checked with any external archiver (WinRAR, 7-ZIP, etc....).

POLINK: error: Unresolved external symbol 'SYS_AllocateString'.
POLINK: fatal error: 1 unresolved external(s).

4.40 Beta 1
gnozal can you fix this error? please

[DoubleDutch]

I think a few of the libs are broken on 4.40, hopefully Gnozal will give us an update soon.

[gnozal]

Because of

- Changed: Call(C)Function(Fast) parameters have been changed from 'Any' to 'Integer'.

I have to change my code to use prototypes.

[gnozal]

Here a PureZIP V2 version compiled with PB4.40 BETA 1 : http://freenet-homepage.de/gnozal/PureZIP_440.zip

Please test.

Note : if you upgrade from PureZIP 1.xx, please note that PureZIP V2 requires an additional parameter for the compression and progression callbacks.

Experimenting with PureZIP to unpack zip files, I find it runs in 1/3 the time MS Expand All takes (using 180MB zip file with many files). What is PureZip NOT doing and does it matter?

Secondly, my 3-line PureZIP unzipper app (simply calling PureZIP_ExtractFiles ) returns control to the WinXP command shell way before the files appear in the explorer or to the DIR command - do I need some sort of delay/wait in my app when I unzip a folder before I can see all the files in it?

Thirdly, can I use PureZip to unzip just a selected folder (e.g. with a filespec like "fred\innerFolder\things\*.jpg") ? I have a zip file with a complex internal folder hierarchy and I'm only interested in the content of a particular path. I suspect that PureZIP is so fast that this requirement is mostly irrelevant.

Thanks for PureZIP and PureBasic - at first sight it seems to be a dose of sanity in the increasingly complex and baffling software dev world.

I don't know what MS does
However PureZIP uses the ZLIB library so it should do what matters.

I never use the MS explorer (I am totally addicted to Total Commander) so I can only guess : it's some refresh delay, which you can probably force by sending some message to the explorer.

With the PureZIP_Archive_* functions, you can parse a ZIP archive (PureZIP_Archive_FindFirst()/PureZIP_Archive_FindNext()) and only extract some of the archived files (PureZIP_Archive_Extract()) based on the archived path (PureZIP_Archive_FileInfo()).

gnozal tell PureZip supports unpacking zip (RAW) archive without heading from memory
(1 file without zip a heading format)?
