public:
event EventHandlerEx^ ConnectedChangedEx();This event is raised when the value of the Object.Connected property changes. The value of the Object.Connected property changes whenever a TCP connection to a resource is either made or closed.
This event is useful in several scenarios, for example:
If you are using the PowerTCP component as a reference, you must create a method to handle the event yourself. For more information on using events using PowerTCP.NET within the Visual Studio.NET environment, see Using Events In PowerTCP.
The following example demonstrates using the ConnectedChanged event to notify the user of the status of the connection.
[Visual Basic]
Private Sub Tcp1_ConnectedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Tcp1.ConnectedChanged
' Get current state of connection
If Tcp1.Connected Then
Debug.WriteLine("Connection made")
' Display info about the local/remote endpoints
Debug.WriteLine("Local endpoint: " + Tcp1.LocalEndPoint.ToString())
Debug.WriteLine("Remote endpoint: " + Tcp1.RemoteEndPoint.ToString())
Else
Debug.WriteLine("Connection closed")
End If
End Sub
[C#]
private void tcp1_ConnectedChanged(object sender, System.EventArgs e)
{
// Get current state of connection
if(tcp1.Connected)
{
Debug.WriteLine("Connection made");
// Display info about the local/remote endpoints
Debug.WriteLine("Local endpoint: " + tcp1.LocalEndPoint.ToString());
Debug.WriteLine("Remote endpoint: " +
tcp1.RemoteEndPoint.ToString());
}
else
Debug.WriteLine("Connection closed");
}
