retrieve image size+download with progressbar ( from the web )

[dynamic_sysop]

hi dudes, another little project i knocked up for fun . this will allow you to get the size of a file on the net , then download it with a progressbar to indicate how it's going.
i built one with SavefileDialog option also, but to reduce the code being posted this will save a default image name to your app's bin folder.
ok , first you need a reference to these 2 at the top of your form ...

Imports System.Net
Imports System.IO

then a command button and a progressbar ( Button1 and Progressbar1 ) then drop this code in ...

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Dim imgPath As String = "http://www.google.com/images/logo.gif"
 
            Dim wRequest As HttpWebRequest = DirectCast(HttpWebRequest.Create(imgPath), HttpWebRequest)
            Dim wResponse As WebResponse = DirectCast(wRequest.GetResponse(), WebResponse)
 
            Dim sWriter As FileStream = New FileStream("new.gif", FileMode.OpenOrCreate)
            Dim ContentLength As Integer = wResponse.ContentLength
 
            Dim sizeInKB As String = (ContentLength / 1024).ToString()
            Me.Text = "The Size of the Image is: " & sizeInKB.Substring(0, sizeInKB.IndexOf(".") + 3) & "KB"
 
            Dim buffer(ContentLength) As Byte
            Dim length As Integer = ContentLength
            Dim position As Integer = 0
            Dim complete As Integer = 1
            Dim returned As Integer = 0
 
            ProgressBar1.Value = 0 '/// clear the progressbar.
            ProgressBar1.Maximum = ContentLength '/// set it's length.
 
            While Not complete = 0
                position = wResponse.GetResponseStream().Read(buffer, returned, length)
                sWriter.Write(buffer, returned, position)
                complete = position
                returned += position
                length -= position
                ProgressBar1.Step = returned
                ProgressBar1.PerformStep()
            End While
 
            Me.Text = "Completed download"
            sWriter.Close()
            wRequest = Nothing
 
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        Catch webex As WebException
            Console.WriteLine(webex.Message)
        End Try
    End Sub

i've included a sample project ...
