Parse text out of URL

I need to be able to grab a part of a URL and place in a textbox.
I want to grab the last part of the URL from a textbox, and place in another textbox. I need everything from the end of the url, to the last /.
Example:
textbox1.text = "http://www.site.com/stuff/stuffz/thing.exe
textbox2.text = "thing.exe"

I have tried using the function and code below, but it doesn't work the way I need it.

It just returns the URL without the / 's.

Any help is appreciated.
Public Function midReturn(ByVal first As String, ByVal last As String, ByVal total As String) As String
        If last.Length < 1 Then
            midReturn = total.Substring(total.IndexOf(first))
        End If
        If first.Length < 1 Then
            midReturn = total.Substring(0, (total.IndexOf(last)))
        End If
        Try
            midReturn = ((total.Substring(total.IndexOf(first), (total.IndexOf(last) - total.IndexOf(first)))).Replace(first, "")).Replace(last, "")
        Catch ArgumentOutOfRangeException As Exception
        End Try
    End Function
 
    Private Sub btnClip_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClip.Click
 
        txtName.Text = midReturn("/", "", txtLink.Text)
 
    End Sub

Hello zerogeek,

txtName.Text = txtLink.Text.Substring(txtLink.Text.LastIndexOf("/")+1)

Should do it.

Regards,

This should do what you need.
Set up a page with to textboxes on it and please test.
I have set this up in the Page_Load Event however you put this in a function.

Hope this helps

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim s As String = "http://www.site.com/stuff/stuffz/thing.exe"
        Dim lengthOfFullString As Integer = s.Length
        Dim i As Integer = s.LastIndexOf("/")
        Dim texbox1Text As String = s.Remove(i) ' If you want the / at the end then just add + "/"
        Dim texbox2Text As String = s.Substring(i)
        Me.TextBox1.Text = texbox1Text
        Me.TextBox2.Text = texbox2Text
    End Sub
