Demonstrates the QuickGet method. VB.NET

Dim success As Boolean = False

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

Dim http As New Chilkat.Http

' This URL is valid and can be tested...
Dim zipBytes() As Byte

    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


If (http.LastStatus <> 200) Then
    Debug.WriteLine("Response status code: " & http.LastStatus)
    Debug.WriteLine(http.LastResponseBody)
    Exit Sub
End If


Dim zip As New Chilkat.Zip

' Open the zip from the bytes contained in bd.
success = zip.OpenFromMemory(zipBytes)
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)

End If


' Get the entry for the file we want..
Dim entry As New Chilkat.ZipEntry

    Exit Sub
End If


' The XML in this case is about 274K, so let's just examine the last 20 lines...
Dim sb As New Chilkat.StringBuilder
