How Do I...Use message formatters?



Message queuing makes it easy for application developers to communicate with application programs quickly and reliably by sending and receiving messages. Messaging provides you with guaranteed message delivery and a robust, fail-safe way to carry out many of your business processes.

The MessageQueue component allows you to easily incorporate message-based communication into your applications. Using this component and its associated language features, you can send and receive messages, explore existing queues, create and delete queues, and perform a variety of other operations using a simple programming model.

The sample illustrates how to use the MessageQueue component to use different serialization mechanisms to send objects through a message queue. To run the sample you have to have Message Queuing installed on your system.

Selecting a serialization mechanism is as simple as changing the value of one property. Here are some examples:
  1. Send a message using an XML based serialization mechanism:

    mq.Formatter = new XmlMessageFormatter(); mq.Send(order); mq.Formatter = New XmlMessageFormatter() mq.Send(order) mq->Formatter = new XmlMessageFormatter; mq->Send(order);


  2. Send a message using a binary serialization mechanism:

    mq.Formatter = new BinaryMessageFormatter(); mq.Send(order); mq.Formatter = New BinaryMessageFormatter() mq.Send(order) mq->Formatter = new BinaryMessageFormatter; mq->Send(order);


  3. Send a message using a serialization mechanism which is compatible with the MSMQ ActiveX Formatter:

    mq.Formatter = new ActiveXMessageFormatter(); mq.Send(order); mq.Formatter = New ActiveXMessageFormatter() mq.Send(order) mq->Formatter = new ActiveXMessageFormatter; mq->Send(order);
