LineAdded Event

Occurs when a new line device is added to the system.

Declaration Syntax

Visual Basic

Visual C++

public static event TapiEventHandler LineAdded

Public Shared Event LineAdded As TapiEventHandler

public:
static  event TapiEventHandler^ LineAdded {
	void add (TapiEventHandler^ value);
	void remove (TapiEventHandler^ value);
}

Remarks

This event occurs when a new telephony line device is detected while the application is running, for example, when a USB modem is connected to the system. New TapiLine object is added to the Lines collection before this event is fired.

Note:
In Windows Forms application AddTapi.NET executes the handler of this event on the main thread of the application (the thread that called Initialize(String)). It is safe to access Windows Forms controls from the event handler without using Invoke mechanism.

Examples

The following code shows how to process LineAdded event.

            TapiApp.Initialize("MyApp");
            TapiApp.LineAdded += OnLineAdded;
            ...
            
            void OnLineAdded(object sender, TapiEventArgs args)
            {
                // Display the name of newly added line
                Console.WriteLine("{0} added", args.Line.Name);
            }

VB.NET

            TapiApp.Initialize("MyApp")
            AddHandler TapiApp.LineAdded, AddressOf OnLineAdded
            ...
            
            Private Sub OnLineAdded(ByVal sender As Object, ByVal args As TapiEventArgs)
                ' Display the name of newly added line
                Console.WriteLine("{0} added", args.Line.Name)
            End Sub
