I require to download a set of files i.e this is a updater for changes withing the database to be downloaded from the internet.

I need to add a progress meter into program I've tried looking for the right event but with no joy.

The code below works as it was taken from 101 samples of VB.NET anyway

Visual Basic: 
        Dim fs As FileStream	
        Dim req As WebRequest

        Try
            req = WebRequest.Create("http://www.website.com/filename.pdf")

            req.Method = "GET"

            Dim rsp As WebResponse = req.GetResponse()

            Try
 
                fs = New FileStream("ReceivedXMLFile.pdf", FileMode.Create)

                CopyData(rsp.GetResponseStream(), fs)

                Msgbox (CStr(rsp.ContentLength / 1024) & " KB's Downloaded")

            Catch exp As Exception
                MessageBox.Show(exp.Message, Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Stop)

            Finally

                If Not rsp Is Nothing Then rsp.GetResponseStream.Close()
                If Not fs Is Nothing Then fs.Close()

Please help

Cheers

You may well find yourself having to write the code to connect to the webserver using a Socket or TcpClient yourself, I'm not aware of a framework method to download files from http and give transfer progress.
 
I don't, but perhaps someone else will.

It won't get more complex than reading the HTTP RFC, connecting to the webserver on port 80, issuing a GET request for the file, examining the Content-Length header then storing the data as you receive it.
