How to make z7 from vb.net

Answer 1

We use SharpZipLib to zip/unzip files and/or folders from .Net. SharpZipLib is released with a GNU General Public License.

Answer 2

If you're using 7-zip you'll need to start a new Process to execute 7z.exe and pass in a string of arguments:

    Dim objProcess As System.Diagnostics.Process
    Try
        objProcess = New System.Diagnostics.Process()
        objProcess.StartInfo.FileName = "7z.exe"
        objProcess.StartInfo.Arguments = "u -tzip classics.zip classics -r"
        objProcess.Start()

        'Wait until the process passes back an exit code 
        objProcess.WaitForExit()

        'Free resources associated with this process
        objProcess.Close()
    Catch
        MessageBox.Show("Could not start process " & ProcessPath, "Error")
    End Try

To work out what the arguments should be, do the zipping from a command line first (I.e. 7z.exe u -tzip classics.zip classics -r).
