I am trying to create an updater for my program which automatically download's the latest version of my program from the web. Now I want this process to be done using a progress bar (so when the download progress is at 50% the progress bar is half-way through). This is my code: Private Sub client_ProgressChanged(ByVal sender As Object, ByVal e As DownloadProgressChangedEventArgs) Dim bytesIn As Double = Double.Parse(e.BytesReceived.ToString()) Dim totalBytes As Double = Double.Parse(e.TotalBytesToReceive.ToString()) Dim percentage As Double = bytesIn / totalBytes * 100 client.Value = Int32.Parse(Math.Truncate(percentage).ToString()) End Sub Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim url As String = "MY DOWNLOAD LINK" 'Download Dim client As WebClient = New WebClient AddHandler client.DownloadProgressChanged, AddressOf client_ProgressChanged AddHandler client.DownloadFileCompleted, AddressOf client_DownloadCompleted client.DownloadFileAsync(New Uri(url), "C:\Users\User\Desktop\BACKUP\TESTING\New folder\1.exe") End Sub End Class Now I know that the place where the file is saved has been inputed manually by me , but I will change that later. My problem currently is that the file is not being downloaded. However when I change the DownloadFileAsync method to DownloadFile , my program downloads the file. However with the DownloadFile method I will not be able to use the progress bar to track the download progress. Any help is much appreciated :-)
