QAManagerBase interface

This class acts as a base class for QATransactionalManager and QAManager, which manage transactional and non-transactional messaging, respectively.

Visual Basic
Public Interface QAManagerBase
public interface QAManagerBase

Use the QAManagerBase.Start() method to allow a QAManagerBase instance to listen for messages. There must be only a single instance of QAManagerBase per thread in your application.

You can use instances of this class to create and manage QAnywhere messages. Use the QAManagerBase.CreateBinaryMessage() method and the QAManagerBase.CreateTextMessage() method to create appropriate QAMessage instances. QAMessage instances provide a variety of methods to set message content and properties.

To send QAnywhere messages, use the QAManagerBase.PutMessage method to place the addressed message in the local message store queue. The message is transmitted by the QAnywhere Agent based on its transmission policies or when you call QAManagerBase.TriggerSendReceive().

For more information about qaagent transmission policies, see Determining when message transmission should occur on the client.

Messages are released from memory when you close a QAManagerBase instance using the QAManagerBase.Close method.

You can use QAManagerBase.LastError and QAManagerBase.LastErrorMessage to return error information when a QAException occurs. You may also obtain the error information from the QAException object.

QAManagerBase also provides methods to set and get message store properties.

For more information, see Client message store properties and the MessageStoreProperties class.
