Dim success As Boolean = False

'  This example assumes the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

Dim zip As New Chilkat.Zip

success = zip.OpenZip("qa_data/zips/sample.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)

End If


Dim numEntries As Integer = zip.NumEntries

Dim entry As New Chilkat.ZipEntry

Dim i As Integer = 0
While i < numEntries
    zip.EntryAt(i,entry)
    '  Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries. 
    '  However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
    '  An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file. 
    '  It usually has a directory name with a trailing slash (/) and zero-length content.
    If (entry.IsDirectory) Then
        Debug.WriteLine(i & ": " & entry.FileName & " (directory)")
    Else
        Debug.WriteLine(i & ": " & entry.FileName)
    End If

    i = i + 1
End While
