Syntax

HRESULT MQMgmtAction(
  LPCWSTR pMachineName, 
  LPCWSTR pObjectName, 
  LPCWSTR pAction 
);

pMachineName
[in] Pointer to a Unicode string that contains the name of the computer where the action will take place. Must be set to NULL in the embedded version of MSMQ.

Value	Description
L"MACHINE"	Required when reading properties of the queue manager.
L"QUEUE=<formatname>"	Required to act on a specific queue on the computer.

pAction
[in] Pointer to a string that indicates the action to be performed on the computer.

The following values are defined in the Mqmgmt.h file.

Value	Description
MACHINE_ACTION_CONSOLE	Brings up the MSMQ console (debug version).
MACHINE_ACTION_CONNECT	Connects the computer to the network and to the directory service.
MACHINE_ACTION_DISCONNECT	Disconnects the computer from the network and from the directory service.
MACHINE_ACTION_EXIT	Exits manual mode.
MACHINE_ACTION_SHUTDOWN	Stops the MSMQ service.
MACHINE_ACTION_STARTUP	Starts the MSMQ service.
MACHINE_ACTION_TIDY	Cleans up empty message files every six hours. This is helpful when many messages are deleted (purged or received by an application) and the application needs the disk space available immediately.
QUEUE_ACTION_DELMSG	Deletes a message in the queue.
QUEUE_ACTION_EOD_RESEND	Resends the pending transaction sequence.
QUEUE_ACTION_PAUSE	Valid for outgoing queues only. Stops the sending of messages from the computer. The queue manager will not send messages to the applicable destination queue until a RESUME action is initiated.
QUEUE_ACTION_PURGE	Purges the queue (deletes all messages in the queue). Use MQMgmtAction with this option. MSMQ does not support a separate MQPurgeQueue function like the desktop version of MSMQ.
QUEUE_ACTION_RESUME	Only valid for outgoing queues. Restarts the sending of messages after a PAUSE action has been initiated.

MQ_ERROR_ACCESS_DENIED (0xC00E0025)
The process does not have the access rights to perform management actions on the queue or computer.

MQ_ERROR_ILLEGAL_FORMATNAME (0xC00E001E)
The specified format name in pObjectName is illegal.

MQ_ERROR_SERVICE_NOT_AVAILABLE (0xC00E000B)
Cannot connect to the queue manager.
