Program settings have the advantage that they are strongly typed and they should also work on even on platforms that do not have a Registry, such as a Unix system using Mono to run a Visual Basic .NET application. (Although I haven't tried this because I don't have Unix installed. If you try it, let me know how it works.)

To make the settings, open the project's Properties pages and select the Settings tab. Create Integer settings named Left, Top, Width, and Height. Give them some reasonable default values to use when the program first starts.

When the program starts, the following code loads the form's settings.

' Reload the previously saved settings.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal _
    e As System.EventArgs) Handles MyBase.Load
    Me.Left = My.Settings.Left
    Me.Top = My.Settings.Top
    Me.Width = My.Settings.Width
    Me.Height = My.Settings.Height
End Sub

' Save the current settings.
Private Sub Form1_FormClosed(ByVal sender As Object, ByVal _
    e As System.Windows.Forms.FormClosedEventArgs) Handles _
    Me.FormClosed
    My.Settings.Left = Me.Left
    My.Settings.Top = Me.Top
    My.Settings.Width = Me.Width
    My.Settings.Height = Me.Height
End Sub
