better way

[cdubb07]

what is a better way to write this, i want it to be able to read the file, then replace the text in the file.

Private Sub Button10_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button10.Click
        IO.File.Delete("dtmbuffer.txt")
        IO.File.Copy("dtm.txt", "dtmbuffer.txt")
        Dim dtm As IO.StreamReader = IO.File.OpenText("dtmbuffer.txt")
        Dim dtm2 As IO.StreamWriter = IO.File.AppendText("dtm.txt")
        Try
            Select Case dtm.ReadLine()
                Case Is = 1
                    MsgBox("Task Manager is already disabled.")
                    Me.Close()
                Case Is = 0
                    Registry.CurrentUser.CreateSubKey("Software\Microsoft\Windows\CurrentVersion\Policies\System")
                    Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Policies\System", True).SetValue("disabletaskmgr", "1")
                    dtm2.WriteLine("1")
                    MsgBox("Task Manager is now disabled.")
                    Me.Close()
            End Select
 
        Catch ex As Exception
 
        End Try
    End Sub

Why don't you query the registry to begin with, rather than depending on a text file?
