Introduction

dotNETSender is a simple application which provides a neat GUI for the windows “net send” command. It looks like MSN Messenger; you can add/delete/edit contacts in the contact list. If the contact’s computer is turned off, the corresponding node will show an offline icon. When minimized, the application runs in the system tray.

Description

This is a good piece of code for beginners to get an idea about threading in C#, delegates and events, registry operations, file operations and invoking another process from within the program.

The elements in the tree are mapped to objects in the contact list. The Contact class encapsulates the functionality and properties of a contact. The ContactList class holds a collection of Contact objects as a array property. The functions in the NetSender class are used to send messages and also to check whether a contact’s machine is turned off or not.

When the Refresh function in ContactList class runs, it fires an event, the form class is subscribed to this event and when it receives the event, the tree view gets refreshed.

After being minimised to the tray, the hidden application window can be restored by double-clicking the system tray icon.
