An error occurred when accessing a Message Queuing method.

Examples

The following code example gets and sets the value of a message queue's MaximumQueueSize property.

// Set the queue's MaximumQueueSize property value.
queue.MaximumQueueSize = 10;

// Display the new value of the queue's MaximumQueueSize property.
Console.WriteLine("MessageQueue.MaximumQueueSize: {0}",
    queue.MaximumQueueSize);

Remarks

The MaximumQueueSize provides access to the Message Queuing message storage limit, which is separate from the computer's message quota that the administrator defines. For more information about the message quota, see MaximumJournalSize.

Setting this property modifies the Message Queuing queue. Therefore, any other MessageQueue instances are affected by the change

If an attempt is made to exceed either the maximum queue size or the computer message quota, messages might be lost. When the queue quota is reached, Message Queuing notifies the administration queue of the sending application to indicate that the queue is full, by returning a negative acknowledgment message. Message Queuing continues to send negative acknowledgments until the total size of the messages in the queue drops below the limit.
