So you mean add a new link to the listbox? And then download the selected item from the listbox when the user presses the button?

Keep an independent list of stuff. In C#, you'd do it like so:

List<KeyValuePair<string, string>> items = new List<KeyValuePair<string, string>>();

void PopulateItems()
{
foreach (KeyValuePair<string, string> item in items)
ListBox1.Items.Add(item.Key);
}

void DownloadLinks()
{
foreach (KeyValuePair<string, string> item in items)
(new WebClient()).DownloadFile("C:\Dest", item.Value); // example download code. replace with yours.
}

void DownloadSelectedLink()
{
foreach (KeyValuePair<string, string> item in items)
if (ListBox1.SelectedText == item.Key)
{
(new WebClient()).DownloadFile("C:\Dest", item.Value); // example download code. replace with yours.
break;
}
}

void AddItem(string name, string URL)
{
items.Add(new KeyValuePair<string, string>(name, URL);
}

Sorry for the non-tabbing, did it on phone which has no tab key.

edit: why am i spoonfeeding? :/

if you want it to go to a download link then do this:

If Listbox1.SelectedItem = "put what item you want here" Then
Try
    Process.Start("put the download link in here")
Catch ex As Exception

End Try
End If

that will work if you want it to take you to a download link

thnks but i want it where i can put the file i want in to the list box an have it directly downloaded from the list box to where ever they want to save that file to

Well, the listbox control doesn't have any features to allow you to have a displayed entry and a secondary value

i.e your current listbox has

SnowBird Webbrowser.zip

But the link is obviously not that. The way I would handle this problem is to use a dictionary(Of String, String)

Here's an example I wrote up quickly:

First, the dictionary:
[highlight=vb.net]
Private linkDictionary As New Dictionary(Of String, String)
[/highlight]

Now declare the following methods:

[highlight=vb.net]
Private Sub updateListBox(ByVal lBox As ListBox, ByVal vals As Dictionary(Of String, String))
lBox.Items.Clear()
For Each kvp As KeyValuePair(Of String, String) In vals
lBox.Items.Add(kvp.Key)
Next
End Sub

Private Sub addToListBox(ByVal lBox As ListBox, ByVal display As String, ByVal link As String, ByRef vals As Dictionary(Of String, String))
Try
vals.Add(display, link)
updateListBox(lBox, vals)
Catch keyNfound As ArgumentException
If keyNfound.Message.ToLower.Contains("already been added") Then MessageBox.Show("An item with that name is already in the listbox, please pick a unique name!", "Error: Duplicate entry", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub

Private Sub removeFromListBox(ByVal lBox As ListBox, ByVal curItem As String, ByRef vals As Dictionary(Of String, String))
vals.Remove(curItem)
updateListBox(lBox, vals)
End Sub
[/highlight]

Now you just use those methods to do what they say:

i.e to add an item to the listbox
[highlight=vb.net]
addToListBox(ListBox1, "Hello.zip", "https://www.example.com/files/hello.zip", linkDictionary)
[/highlight]
to remove an item from the listbox:
[highlight=vb.net]
removeFromListBox(ListBox1, ListBox1.SelectedItem.ToString, linkDictionary)
[/highlight]
to get the link associated with the current file:
[highlight=vb.net]
MessageBox.Show(getValue(ListBox1.SelectedItem.ToS tring, linkDictionary))
[/highlight]

So to download you would simply download the 'getValue' result.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
     
        Dim location As String

        Dim ofd As New SaveFileDialog
        ofd.Filter = "*.zip|*.zip|*.rar|*.rar"
        ofd.FileName = "Download"
        If ofd.ShowDialog = Windows.Forms.DialogResult.OK Then
            Dim lvi As New ListViewItem(ofd.FileName)
            location = (ofd.FileName)
            My.Computer.Network.DownloadFile(" " + ListBox1.SelectedItem.ToString, location)

        End If

        log1.Items.Add("Item " + ListBox1.SelectedItem.ToString + " Was Downloaded")
      end sub 
end class

thats what i did but it not showing up in the list box im trying to get it from my desktop as a location but it not working

What even? you didn't use any of the code I posted, and I don't see a single ListBox.Items.Add method there so no shit there won't be anything in your textbox.

Read mai post. ListBox doesn't have a special object for it's items hence no Tag, Unless you code your own custom shit, you won't have a tag property.
