How Do I...Send a message to a message queue?



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 send a simple message to a message queue. To run the sample, you have to have Message Queuing installed on your system. The sample is a command-line application that takes two command-line arguments. The first argument is a name of a message queue. The path does not have to refer to an existing queue. If the queue does not exist, it will be created for you. The second command-line argument is the message to be written to the queue. For example you can run it as follows:

MQSend.exe MyQueue "Hello World!"


Now, open the Message Queuing console and examine the MyQueue message queue. It should have a message in it.

In its simplest form, sending a message to a message queue involves:
  1. Creating an instance of the MessageQueue component and setting its Path property:

    		
    MessageQueue mq = new MessageQueue(".\\MyQueue");
    
    C#


  2. Calling Send method to send the message:

    		
    mq.Send("Hello World!");
    
    C#


Example



VB MQSend.exe
