// 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
success = fileData.LoadFile("qa_data/xml/hamlet.xml")
If (success <> True) Then
    System.DebugLog("Failed to load file.")
    Return
End If

// In-place compress the contents of fileData
success = gzip.CompressBd(fileData)
If (success <> True) Then
    System.DebugLog(gzip.LastErrorText)
    Return
End If

// Get the base64 encoded compressed data (in a single line).
Dim strBase64 As String
strBase64 = fileData.GetEncoded("base64")
System.DebugLog(strBase64)
System.DebugLog("--------")

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