queue->MessageReadPropertyFilter->
IsLastInTransaction = true;
// Peek at the message. Time out after ten seconds
// in case the message was not delivered.
orderMessage = queue->Peek(TimeSpan::FromSeconds(10.0));
// Display the value of the message's
// IsLastInTransaction property.
Console::WriteLine("Message.IsLastInTransaction: {0}",
orderMessage->IsLastInTransaction);
// Set the queue's MessageReadPropertyFilter property to enable the
// message's IsLastInTransaction property.
queue.MessageReadPropertyFilter.IsLastInTransaction = true;
// Peek at the message. Time out after ten seconds in case the message
// was not delivered.
orderMessage = queue.Peek(TimeSpan.FromSeconds(10.0));
// Display the value of the message's IsLastInTransaction property.
Console.WriteLine("Message.IsLastInTransaction: {0}",
orderMessage.IsLastInTransaction);
