Initialize QAnywhere.

This step is the same as in non-transactional messaging.

using iAnywhere.QAnywhere.Client;

Create a QATransactionalManager object.

For example, to create a default QATransactionalManager object, invoke CreateQATransactionalManager with null as its parameter:

QAManager mgr;
mgr = 
  QAManagerFactory.Instance.CreateQATransactionalManager( 
  null );

See QAManagerFactory class.

You can alternatively create a QATransactionalManager object that is customized using a properties file. The properties file is specified in the CreateQATransactionalManager method:

mgr = 
  QAManagerFactory.Instance.CreateQATransactionalManager( 
  "qa_mgr.props" );

where qa_mgr.props is the name of the properties file that resides on the remote device.

Initialize the QAManager object.

mgr.Open();

Initialize message objects.

QATextMessage msg_1;
QATextMessage msg_2;

Send the messages.

The following code sends two messages in a single transaction:

msg_1 = mgr.CreateTextMessage();
if( msg_1 != null ) {
  msg_2 = mgr.CreateTextMessage();
  if( msg_2 != null ) {
    if( !mgr.PutMessage( "jms_1\\queue_name", msg_1 ) ) {
      // Display message using mgr.GetLastErrorMsg().
    } else {
      if( !mgr.PutMessage( "jms_1\\queue_name", msg_2 ) ) {
        // Display message using mgr.GetLastErrorMsg().
      } else {
        mgr.Commit();
      }
    }
  }
}

The Commit method commits the current transaction and begins a new transaction. This method commits all PutMessage() method and GetMessage() method invocations.
