PureZIP library : ZIP / UNZIP files

[zikitrake]

another bug

If you have a zip file with 2 files with the same name in differents directories,

For example, you have this tree directory

c:\test\text.txt
c:\test\dir1\text.txt

Code: Select all

Searchfile1.s = "c:\test\text.txt"
ReturnValue1.l = PureZIP_FindFile(ZIPFile$, SearchFile1)

Searchfile2.s = "c:\test\dir1\text.txt"
ReturnValue2.l = PureZIP_FindFile(ZIPFile$, SearchFile2)

ReturnValue1 and ReturnValue2 have the same value (I think it only search for filename without path)

And I would like that

Code: Select all

PureZIP_Archive_Locate()

can Returns file number in archive or add the command

Code: Select all

PureZIP_Archive_FindFile(FileToSearch.s)

(is this possible?)

Thank you!!

Yes, I search only for the filename.
I will add an option to search for the full path.

And I would like that PureZIP_Archive_Locate() returns file number in archive

I simply use the ZLIB unzLocateFile() function wich does not work that way.
And PureZIP_Archive_Locate() is intended to work like the other PureZIP_Archive_*() functions, ie with current file in archive.

But you can do your own FindFileInZIP() function :
- open archive with PureZIP_Archive_Read()
- scan the archive with the PureZIP_Archive_FindFirst() / PureZIP_Archive_FindNext() functions
- and get the file info (including Filename) with PureZIP_Archive_FileInfo
- do what you have to do with the FileName
- close archive with PureZIP_Archive_Close()

yes, actually I use this method. Thank you

Can anyone supply sample usage to Zip a single file for use with Version 4 Beta 7 ?

Can anyone supply sample usage to Zip a single file for use with Version 4 Beta 7 ?

Example with DLL : http://www.purebasic.fr/english/viewtopic.php?t=20370 (see Num3 PB_ZIP post)

That link is a little hard to follow. I have downloaded "purezip.zip" and expanded that into my purebasicbeta program folder. Could someone give me some code to try in v4b7 to zip say c:\test.txt to c:\test.zip.

Maybe the best is to go to Num3's site http://io-soft.planetaclix.pt/software.htm and download his Zlib Procedures http://io-soft.planetaclix.pt/files/Zlib_Procedures.zip

Maybe it's me been a bit slow, but can't seem to find any usage docs on the website or in the zip file. Maybe some kind soul could provide an example?

Code: Select all

Structure tm_date
  tm_sec.l;            /* seconds after the minute - [0,59] */
  tm_min.l;            /* minutes after the hour - [0,59] */
  tm_hour.l;           /* hours since midnight - [0,23] */
  tm_mday.l;           /* day of the month - [1,31] */
  tm_mon.l;            /* months since January - [0,11] */
  tm_year.l;           /* years - [1980..2044] */
EndStructure

Found the zip.pb example at last.
Using zip.pb (Num 3) on PB4B7 i get the following error message when I try to compile.....

[COMPILER] Line 34: 'Structure' or 'Interface' already declared: tm_date


any ideas?
