Syntax

public abstract class Connection : IConnection, 
	IDisposable

Public MustInherit Class Connection

The Connection type exposes the following members.

Properties

	Name	Description
	IsAvailable	Whether this connection to a Brainboxes Device is available, e.g. online or offline. In case of network TCP connection: this is if the device is pingable on the network. In case of serial connection: this is if the device COM port is listed on the system and not open by another process.
	IsConnected	Whether this connection instance to a Brainboxes Device is active
	Stream	The Connections underlying stream class
	Timeout	The timeout for Stream reads and writes, and connection availability test

Methods

	Name	Description
	Connect	Connect to the ED Device
	Create	Supply a connection IP address or com port and the correct IConnection concrete class will be created and returned Examples IConnection c1 = Connection.Create("192.168.0.5"); // returns a TCPConnection class IConnection c2 = Connection.Create("COM6", 9600); //returns a SerialConnection class with the baud rate set to 9600
	Disconnect	Disconnect from the ED Device
	Dispose	Dispose of this Brainboxes device
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ToString	ToString (Overrides ObjectToString.)

Events

	Name	Description
	ConnectionStatusChangedEvent	When the status of the connection changes this event is raised e.g. when IsConnected changes from false to true or when IsAvailable changes: * for example for a TCPConnection if the IP address is goes from on-line to off-line * or for example for a SerialConnection when the COM name is no longer present or in use by another program
