' See Global Unlock Sample for sample code.


Dim zip As New Chilkat.Zip

Dim success As Boolean = zip.OpenZip("qa_data/zips/sample.zip")
If (success <> True) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Unzip to c:/temp/testDir
' If c:/temp/testDir does not yet exist, it will be auto-created.
Dim numFilesUnzipped As Integer = zip.Unzip("c:/temp/testDir")
If (numFilesUnzipped < 0) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' If, for example, the zip contained these files:

' aaa/pigs.json
' bbb/base64Cert.txt
' bbb/sub1/brasil_cert.pem
' bbb/sub2/penguins.gif
' bbb/sub2/starfish.jpg
' hamlet.xml
' hello.pdf

' then after unzipping, the following files will be created:

' c:/temp/testDir/aaa/pigs.json
' c:/temp/testDir/bbb/base64Cert.txt
' c:/temp/testDir/bbb/sub1/brasil_cert.pem
' c:/temp/testDir/bbb/sub2/penguins.gif
' c:/temp/testDir/bbb/sub2/starfish.jpg
' c:/temp/testDir/hamlet.xml
' c:/temp/testDir/hello.pdf
