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

Dim gzip As New Chilkat.Gzip

' This example will load a file into the fileData object.
' Your application might load fileData from other sources..
Dim fileData As New Chilkat.BinData
Dim success As Boolean = fileData.LoadFile("qa_data/xml/hamlet.xml")
If (success <> True) Then
    Debug.WriteLine("Failed to load file.")
    Exit Sub
End If



' In-place compress the contents of fileData
success = gzip.CompressBd(fileData)
If (success <> True) Then
    Debug.WriteLine(gzip.LastErrorText)
    Exit Sub
End If


' Get the base64 encoded compressed data (in a single line).
Dim strBase64 As String = fileData.GetEncoded("base64")
Debug.WriteLine(strBase64)
Debug.WriteLine("--------")

' To get the base64 in multiple lines, as it might appear in MIME,
' use "base64-mime".
Dim strBase64MultiLine As String = fileData.GetEncoded("base64-mime")
Debug.WriteLine(strBase64MultiLine)
