Occurs when existing line device is removed.

Namespace: Traysoft.AddTapi
Assembly: Traysoft.AddTapi (in Traysoft.AddTapi.dll) Version: 6.0.0.1110

Syntax

public static event TapiEventHandler LineRemoved

Public Shared Event LineRemoved As TapiEventHandler

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

Value

Type: Traysoft.AddTapiTapiEventHandler

Remarks

This event occurs when a telephony line device is removed while the application is running, for example, when a USB modem is disconnected. TapiLine object representing the removed device is removed from the Lines collection before this event is fired.

Note
In Windows Forms and WPF applications 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 or WPF controls from the event handler without using Invoke mechanism.

Examples

The following code shows how to handle LineRemoved event.

C++

Copy

TapiApp.Initialize("MyApp");
TapiApp.LineRemoved += OnLineRemoved;
...

void OnLineRemoved(object sender, TapiEventArgs args)
{
    // Display the name of the removed line
    Console.WriteLine("{0} has been removed", args.Line.Name);
}

TapiApp.Initialize("MyApp")
AddHandler TapiApp.LineRemoved, AddressOf OnLineRemoved
...

Private Sub OnLineRemoved(ByVal sender As Object, ByVal args As TapiEventArgs)
    ' Display the name of the removed line
    Console.WriteLine("{0} has been removed", args.Line.Name)
End Sub
