Dim success As Long
success = 0

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

Dim zip As New ChilkatZip

success = zip.OpenZip("qa_data/zips/test.zip")
If (success = 0) Then
    Debug.Print zip.LastErrorText
    Exit Sub
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.
Dim numEntries As Long
numEntries = zip.NumEntries
Debug.Print "NumEntries = " & numEntries

Dim entry As New ChilkatZipEntry
Dim i As Long
i = 0
Do While i < numEntries
    success = zip.EntryAt(i,entry)
    If (entry.IsDirectory = 0) Then
        Dim fileData() As Byte
        fileData = entry.Inflate()
        ' Do whatever you wish with the file data...
    End If

    i = i + 1

zip.CloseZip
