' See Global Unlock Sample for sample code.

Dim zip As New Chilkat.Zip
Dim success As Boolean

Dim zipPath As String = "c:/temp/test.zip"

' Initialize the zip object, which also sets the FileName property to the path of the zip to be created.
zip.NewZip(zipPath)

' Append a new and empty file to the zip object.
' This does not write the zip file.  It simply adds an entry
' that will get processed when the zip is written.
Dim entry1 As Chilkat.ZipEntry = zip.AppendNew("empty.txt")


' Append another entry..
Dim entry2 As Chilkat.ZipEntry = zip.AppendNew("abc/helloWorld.txt")

' Add some data to this entry..
entry2.AppendString("Hello World","utf-8")


' Write the zip, which contains 2 files:  empty.txt and helloWorld.txt
zip.FileName = zipPath
success = zip.WriteZipAndClose()
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Success.")
