What is the Dispose method in Visual Basic

MSDN generally has good API documentation, you can read about Dispose here:

http://msdn.microsoft.com/en-us/library/system.idisposable.dispose(v=VS.80).aspx

Any object that impliments IDisposable, you should call Dispose when you're done with it.

        If frmSettings.ShowDialog = Windows.Forms.DialogResult.OK Then
          'do Something
        End If
        frmSettings.Close()
        frmSettings.Dispose()



Here is a good starting point for further reading.
