[VB6] 7-zip support

[wqweto]

I don't think 7-zip has support for *compressing* in tar.gz format, most probably only extraction is available.

No, 7-zip supports both .tar and .gz and both compression and decompression. Replied with more details to your other thread.

cheers,

Hi
That command line looks interesting, how can I use it in Visual Basic 6?, In the 'Immediate' window?, How do you use the tar.exe?

I thank you for solving my doubt in the question I asked here: https://www.vbforums.com/showthread....Visual-Basic-6, I was almost about to have to relearn C++ or Java to make libraries and I don't know what else, to find the best way to get it afloat.

Thank you, go ahead, I wish you all the best, if I have another question in the future I will let you know, sorry for the inconvenience.

Currently does not extract .rar packages. Vszlib reports .Filecount as zero (0) for rar package.
7z.dll version 18.5.0.0 (18.4.2018)

    With New cVszArchive
        .Init Makepath(App.Path, "7z.dll")
        .OpenArchive SevenZipFile 'file name tested test.rar
        
  Debug.Print .FileCount

        .Extract App.Path & "\Unpacked"
    End With

7zip file manager opens and extracts rar file OK.

does it support winrar format now?

Z. DLL, how is this made? There is no official open source, right? Z. Exe, this is open source can decompress rar, he can only be made into exe, if made into DLL is not a patent infringement? If you change it to a pipe communication console, first create the zip as a memory-mapped file, 7z.exe opens the handle of the compressed package file, and then it needs to decompress a file or a subdirectory inside, and then it writes it to a new memory-mapped file. Then output a console text to complete the decompression, or display the progress of decompression. In this way, the source code is almost unchanged, and the exe can be used as a DLL. Why doesn't Microsoft create a mapping file or a virtual file that can be opened directly by any program?

See the RAR website

Premade DLL and source available for unrar

By the way, there's a ready one at the bottom of the page "UnRAR OCX control" UnRAR OCX control for use within Visual Basic program.

I need to compress single files into gzip format. Is vszlib able to pass switches like parameters are passed?

    With New cVszArchive
        .AddFile "your_file"
        .Parameter("t") = "gzip"
        .CompressArchive "test.gz"
    End With

Equivivalent 7z command line: 7z.exe a -tgzip "test.gz" "your_file"

Edit: It seems to work ok, when using standard gzip '.gz' as extension for the compressed file, otherwise does not create compressed file, thanks.
