VB.NET HTTP Download with percent-done progress monitoring

Here is an example:

    Dim WithEvents http As Chilkat.Http

    Private Sub http_OnPercentDone(ByVal sender As Object, ByVal args As Chilkat.PercentDoneEventArgs) Handles http.OnPercentDone
        ProgressBar1.Value = args.PercentDone
    End Sub

    Private Sub HttpDownloadTest()

        http = New Chilkat.Http()

        Dim success As Boolean

        '  Any string unlocks the component for the 1st 30-days.
        success = http.UnlockComponent("Anything for 30-day trial")
        If (success <> True) Then
            Exit Sub
        End If

        ' Enable event callbacks...
        http.EnableEvents = True

        '  Download the Python language install.
        '  Note: This URL may have changed since this example was created.
        success = http.Download("http://www.python.org/ftp/python/2.5/python-2.5.msi", "python-2.5.msi")
        If (success <> True) Then
            MsgBox("Python Download Complete!")
        End If

        http = Nothing

    End Sub
