I will be at a conference on March 8, 2007. There will be no class that day. In order to make up for the lost time, you are required to go to the following web sites and read the pages.
Polymorphism and Serializing Data: http://www.ondotnet.com/pub/a/dotnet/2002/08/26/serialization.html The web site uses the wrong name for method that deserializes: the name should not have a hyphen in it.
Printing Rich Text: http://support.microsoft.com/default.aspx?scid=kb;en-us;811401 Use this technique to print Rich Text with formatting.
Accessing the Serial Port: http://www.codeproject.com/csharp/SerialCommunication.asp There is a new class in .NET 2.0 that simplifies access to the serial ports.
Also, read the following pages from the Appendices of the text.
