Set Entry Filepath (in output Zip) when Zipping

Demonstrates how to set the path for the file entry within the .zip to something different than the path in the filesystem. Visual Basic 6.0

' This requires the Chilkat Zip API to have been previously unlocked.
' See Unlock Chilkat Zip for sample code.

' When an absolute filepath is passed to AddFile, the path within the .zip
' will be one of two values:  (1) just the filename part if saveExtraPath is 0,
' or (2) the full absolute path, but made relative, if saveExtraPath is 1.
' (For example, "c:/ck2000/appData/UnitTest/qa_data/hamlet.xml" made relative is 
' "ck2000/appData/UnitTest/qa_data/hamlet.xml")

End If

' When a relative path is passed to AddFile, then saveExtraPath does not apply.
' For example, assume our current working directory is "c:/ck2000/appData/UnitTest".  The following
' call to AddFile creates an entry with the filepath "qa_data/hamlet.xml".
success = zip.AddFile("qa_data/hamlet.xml",saveExtraPath)

' The output so far is:

' 	0: hamlet.xml
' 	1: qa_data/hamlet.xml

' If we write the .zip as-is, then the zip will have two entries
' with the filepaths as shown above.

' This writes "qa_output/zipA.zip"
success = zip.WriteZip()
