Link to reset a password

  1. 'Hello

    I am hoping to send a link to a user who has forgotten his password. The page is online here:

    The code I am using (which is followed by SMTP), is as follows:

    Protected Sub btnForgot_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnForgot.Click
    Const ConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|students.mdb;"
    Dim uniqueCode As String = Guid.NewGuid().ToString("N")
    Dim recordExists As Boolean = False
    Using conn As New OleDbConnection(ConnectionString)
    Using cmd As OleDbCommand = conn.CreateCommand()
    cmd.CommandText = "UPDATE university SET uniqueCode = @uniqueCode WHERE strEmail = @strEmail"
    cmd.Parameters.AddWithValue("@uniqueCode", uniqueCode)
    cmd.Parameters.AddWithValue("@strEmail", strEmailTextBox.Text.Trim())
    Dim recordsAffected As Integer = cmd.ExecuteNonQuery()
    If recordsAffected <> 0 Then recordExists = True
    End Using
    End Using
    If recordExists Then
    Dim builder As New UriBuilder(Request.Url)
    builder.Path = VirtualPathUtility.ToAbsolute("~/resetPwd.aspx")
    builder.Query = "uniqueCode=" & HttpUtility.UrlEncode(uniqueCode)
    Dim link As String = builder.Uri.ToString()
    I take it that the 'uniqueCode' is the link? If so, where does it come from, please? It is normally a link that the user clicks on and is taken to a password reset page ('resetPwd.aspx' in my case), but what generates the link?

    Thank you.

    No, "builder" is your link. "uniqueCode" is a randomly generated id/text to make sure no 2 links are the same. According to the code, it's the query string (parameter) of the Url/Uri that is being sent.
