Unzip Files to Byte Array

See more Zip Examples

Demonstrates how to unzip each file contained in a .zip to an in-memory byte array. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

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

set zip = CreateObject("Chilkat.Zip")

success = zip.OpenZip("qa_data/zips/test.zip")
If (success = 0) Then
    outFile.WriteLine(zip.LastErrorText)
    WScript.Quit
End If

' Iterate of each entry in the zip.
' An entry can be a file or directory entry.  For each file, unzip to a byte array.
numEntries = zip.NumEntries
outFile.WriteLine("NumEntries = " & numEntries)

set entry = CreateObject("Chilkat.ZipEntry")
i = 0
Do While i < numEntries
    success = zip.EntryAt(i,entry)
    If (entry.IsDirectory = 0) Then
        fileData = entry.Inflate()
        ' Do whatever you wish with the file data...
    End If

    i = i + 1

zip.CloseZip 

outFile.WriteLine("Finished.")

outFile.Close
