' See Global Unlock Sample for sample code.

Dim zip As New Chilkat.Zip

' Intialize the zip object by calling NewZip.

' Add a reference to a file on disk to the zip object.
' (When appending files to a zip, the files are not actually
' read into memory.  References to the file(s) are added.
' When WriteZip is called, the referenced files are streamed in
' and compressed to the .zip.)

' Retrieve the entry object...

' Note: Internally, the zip component retains the name of
' the file referenced.  The current setting of the zip entry's
' FileName property is stored in the .zip when writing.

' The zip written here will contain somethingElse.xml
