The MQMoveMessage function moves messages between a queue and its subqueue, or between two subqueues within the same main queue.

HRESULT MQMoveMessage(  
  QUEUEHANDLE sourceQueue,   
  QUEUEHANDLE targetQueue,   
  ULONGLONG lookupID,   
  ITransaction* pTransaction);  

sourceQueue

[in] A handle of the queue that the message has to be moved from. The source queue must be opened with MQ_RECEIVE_ACCESS, and with either of the following share modes:

MQ_DENY_NONE

MQ_DENY_RECEIVE_SHARE

targetQueue

[in] A handle of the subqueue to which the message is to be moved. The target subqueue must be opened with MQ_MOVE_ACCESS (which requires the user to have peek permission for the queue) and with either of the following share modes:

MQ_DENY_NONE

MQ_DENY_RECEIVE_SHARE

lookupID

[in] The identity of the message that needs to be moved.

pTransaction

[in] A pointer to an ITransaction interface, a constant, or NULL. The value NULL indicates the message is not moved as part of a transaction. The constant values that can be used for this parameter are:

MQ_MTS_TRANSACTION

Ensures that the Message Queuing service (MSMQ) verifies that the application is running in the context of a COM+ transaction. If MSMQ determines that the application is running within the context of a COM+ (Component Services) transaction, the message is moved within the current COM+ transaction. Otherwise, the message is moved outside of a transaction.

MQ_SINGLE_MESSAGE

Specifies that the message is moved in a single-message transaction.

MQ_XA_TRANSACTION

Specifies that the call is part of an externally coordinated, XA-compliant transaction.

The MQMoveMessage function returns an HRESULT.

MQ_OK

Indicates success.

MQ_ERROR_ACCESS_DENIED

The source queue or the target queue was not opened with the proper access mode.

MQ_ERROR_TRANSACTION_ENLIST

MSMQ is unable to enlist in the specified transaction.

MQ_ERROR_TRANSACTION_USAGE

The MQMoveMessage function is invoked as a part of a transaction, but the source or the target queue is not a transactional queue.

MQ_ERROR_DTC_CONNECT

MSMQ is unable to connect to the Microsoft Distributed Transaction Coordinator (DTC).

MQ_ERROR_STALE_HANDLE

Either the source or target queue handles were obtained in a previous session of the MSMQ Queue Manager service.

System_CAPS_ICON_note.jpg Note

Calling MQMoveMessage with a stale source or target queue handle fails with MQ_ERROR_STALE_HANDLE if the queue is local. If the queue is remote, the call fails with 0x80070006 (invalid handle).

MQ_ERROR_INSUFFICIENT_RESOURCES

Insufficient resources to complete the operation.

MQ_ERROR_SERVICE_NOT_AVAILABLE

MSMQ service is not available/running.

If the pTransaction parameter is set to a value other than NULL, the message will be moved from the source queue to the target queue as part of a transaction. The transaction object can be obtained internally from Message Queuing (by calling MQBeginTransaction) or externally from the MS DTC.

The following sample code shows how to move a message from a main queue to a subqueue.

HANDLE sourceQueue = NULL;  
HANDLE targetQueue = NULL;  
LCWSTR wszOrdersQueue =   
               "DIRECT=OS:mymachine\private$\orders;";  
LCWSTR wszRejectedOrdersQueue =   
       "DIRECT=OS: mymachine \private$\orders;rejectedorders";  
// Open the source queue.  
hr = MQOpenQueue(wszOrdersQueue, MQ_RECEIVE_ACCESS,   
                             MQ_DENY_RECEIVE_SHARE, &sourceQueue);  
if (FAILED(hr))  
{  
    return hr;  
}  
// Open the target queue.  
hr = MQOpenQueue(wszRejectedOrdersQueue, MQ_MOVE_ACCESS,   
                                       MQ_DENY_RECEIVE_SHARE, &targetQueue);  
if (FAILED(hr))  
{  
    return hr;  
}  
// Move the message.  
hr = MQMoveMessage(sourceQueue, messageLooukpID, targetQueue, NULL);  
MQCloseQueue(sourceQueue);  
MQCloseQueue(targetQueue);  
return hr;
