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

Dim zip As New Chilkat.Zip

Dim success As Boolean
success = zip.OpenZip("test.zip")
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

Dim entry As Chilkat.ZipEntry
entry = zip.GetEntryByName("hamlet.xml")
// Assume entry is non-null.  If GetEntryByName failed
// to find the entry, it returns a null reference.
entry.FileName = "hamlet2.xml"

entry = zip.GetEntryByName("helloWorld.pl")
entry.FileName = "hw.pl"

// Now unzip to the "test" subdirectory, under our current
// working directory:
Dim numFilesUnzipped As Int32
numFilesUnzipped = zip.Unzip("test")
If (numFilesUnzipped < 0) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

// The filenames within the .zip are unchanged, but it unzipped
// test/hw.pl and test/hamlet2.xm
