)

Exceptions

Exception Condition
ArgumentNullException

receiverName is nulla null reference (Nothing in Visual Basic).

ArgumentException

receiverName is longer than 256 characters.

Remarks

This constructor initializes the ReceiverName property to the specified value, and the NameScope property to Domain. The AllowedSenderDomains property remains nulla null reference (Nothing in Visual Basic), which indicates that the receiver can receive messages only from senders on the same domain.

Examples

The following code example demonstrates how to use this constructor.

' In the receiving application:
Dim messageReceiver As New LocalMessageReceiver("receiver")
AddHandler messageReceiver.MessageReceived, _
    AddressOf receiver_MessageReceived

Try

    messageReceiver.Listen()

Catch ex As ListenFailedException

    MessageBox.Show( _
        "Cannot receive messages." & Environment.NewLine & _
        "There is already a receiver with the name 'receiver'.", _
        "LocalMessageReceiver", MessageBoxButton.OK)

End Try

' In the sending application:
Dim messageSender As New LocalMessageSender("receiver")
AddHandler messageSender.SendCompleted, _
    AddressOf sender_SendCompleted
// In the receiving application:
LocalMessageReceiver messageReceiver = new LocalMessageReceiver("receiver");
messageReceiver.MessageReceived += new 
    EventHandler<MessageReceivedEventArgs>(receiver_MessageReceived);
try
{
    messageReceiver.Listen();
}
catch (ListenFailedException)
{
    MessageBox.Show(
        "Cannot receive messages." + Environment.NewLine +
        "There is already a receiver with the name 'receiver'.",
        "LocalMessageReceiver", MessageBoxButton.OK);
}

// In the sending application:
LocalMessageSender messageSender = new LocalMessageSender("receiver");
messageSender.SendCompleted += new 
    EventHandler<SendCompletedEventArgs>(sender_SendCompleted);
