Hi !
I am Intrested to code the Zip Deflate Algorithm.

For the first step i did my first implemetation of the Huffman Compression.
Found the Code in a Book and the I-Net and then i converted it to

[Edit] The code seem to work well now! (found two Bugs...)

This Code works ...

@webbmeister
Why you are using PB4 ?? IT IS BETA !!! And Buggy !!!
And most of the Userlibraries are not ported to work with PB4 !
(Some are going never to be ported :cry: )

if i try to compile the given example, il get the error "Missing libraryExtensions", so it runs here even not.

You can ...

Stay cool !

I love you for your hard work!! Especially on jaPBe !!

Thanks ...

:oops: I dont remark that gnozal hasn´t made any choice to change compression mode......

If you read the explanation for the Zipfile you see Zipfiles are very easy to made. (i done it yesterday in a quickhack)
Read the appnote-xxxxxxxxx-pk.zip at: ftp://ftp.info-zip.org/pub/infozip/doc and Code ...

@cabaptista
I really agree with gnozal that the kompression strenght an acutual Computer dosn´t itch.

You have 2choices for the User
Kompression or no compression.

if you want, make al list box with the following Picks::wink: :wink: :wink:

Normal (is with compression)
Fastest (is witout ...

Hi gnozal!

I puzzled a bit arround the DOS Formated Date in the PureZIP_GetFileInfo Function.
I found some hints in the WinAPI-Help for the function DosDateTimeToFileTime_().

Here is my solution in pure PureB (only tested on WinXP !):

ArchiveFileName.s = "c:\temp\test.zip"

Procedure.l ...

Sorry for wasting your time!

In the German Forum a guy called Deeem2031, has created runtime optimized PBlibs: Math, Memory and StringExtension.
The StringExtension was the troublemaker.....

Now it is all right!

Thank you for your good work, and support!!!

OK!

I try it on an other (clean) Machine, and report later....

over and out

ok!

i'm using:
WinXP (SP2)

PureBasic 3.93
jaPBe 2.5.4.22

userlibs:
PBOSL
MDB_LIB (Paul Leishow)
PV_gadgets (PurevisionXP,Paul Leishow)
RegINI_lib (Paul Leishow)

Are we in an endles loop ?
I'm posted the error two post before......

When i'm using the PureZIP_Archive_Compress() Function, i'm getting POLINK errors:
multiple data. section
_pballocate_memory
_pb_free_memory

When you could not recapitulate the Errors under WinXP (SP2) and PB 3.93, and you have ...

The code are your examples: :lol:
myzip.s = "c:\purebasic393\program\PureZIP-test.zip"
myzipfile1.s = "C:\PureBasic393\Program\PureCOLOR_TEST_2.pb"
myzipfile2.s = "C:\PureBasic393\Program\PureCOLOR_TEST_3.pb" If PureZIP_Archive_Create(myzip.s, #APPEND_STATUS_CREATE)

@gnozal
Thanks a lot for your hard Work!!!!!!!

I am working under Windows XP and PB 3.93.

The Memorycompress example works fine.

The PureZIP_Archive_Create() command seems to be OK.

But if i try to Compile with PureZIP_Archive_Compress(), i get this error:

HI PB´s!

If you need a Programm that runs in Windows and Dos-Console you can Display Messages in both Know!

WICHTEL and DANILO from the German Forum solved the Problem that a Programm detect if the start caller was DOS or WINDOWS.
Code Looks like:
