I need help making a downloading thing like this:

For example:
You click on Download 1 and it downloads the file to the desktop [the progressbar and the % thing have to work to]

Download 1,2 and 3 has different download links...

First off....You need to figure out how you are going to populate the ComboBox.
Are you using a datasource, textfile, XML file, or are you going to hard code the links in the ComboBox.

As far as downloading from the link. There a several ways of doing it.
But! If this is a software that you entend on letting others use this project you have to think about Firewall issues.

Code: Select all

[Download 1]

OK!
So what type of files will be downloaded?
Is this for a Update feature for a project?
Is this just an app from users to download what ever you are offereing?

These are questions you need to think about.

Download .exe files.
Users download what i am offering

Code: Select all

My.Computer.Network.DownloadFile(ComboBox1.SelectedItem, My.Computer.FileSystem.SpecialDirectories.Desktop + "\" + "FILENAME.EXT")

The FILENAME.EXT needs to be the original filename that is being downloaded

This will download the file to the user Desktop

From what I can tell, you have to use a BackgroundWorker to download the file and as the file downloads, it updates the ProgressBar. I personaly do not how todo this with a BackGroundWorker. Do a Google search on BackgroundWorker Downloadfile in vb.net or vb 2008. See what you come up with.

Hello,

To do a progress bar you could use this:

First the part the downloads the file:

Code: Select all

Dim WebUpdate As System.Net.WebClient
                WebUpdate = New System.Net.WebClient()
                AddHandler WebUpdate.DownloadProgressChanged, AddressOf OnDownloadProgressChanged2
                AddHandler WebUpdate.DownloadFileCompleted, AddressOf OnFileDownloadCompleted2
                WebUpdate.DownloadFileAsync(New Uri("FILE URL HERE"), "SaveFileAsName.exe")

Then just add these subs in your code:

Code: Select all

Private Sub OnDownloadProgressChanged(ByVal sender As Object, ByVal e As System.Net.DownloadProgressChangedEventArgs)
        Dim totalSize As Long = e.TotalBytesToReceive
        Dim downloadedBytes As Long = e.BytesReceived
        Dim percentage As Integer = e.ProgressPercentage
        ProgressBar1.Increment(percentage)
    End Sub


    Private Sub OnFileDownloadCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.AsyncCompletedEventArgs)
        If e.Cancelled Then
        ElseIf Not e.Error Is Nothing Then
            'FILE CANNOT BE DOWNLOADED - DO SOMETHING HERE
        Else
        'FILE HAS DOWNLOADED SUCCESSFULLY - DO SOMETHING HERE
        End If
    End Sub

Hope that helps cooll;
