The ActiveQueues method is received by the server in an RPC_REQUEST packet. In response, the server MUST return an array of strings that contain the format names of all the represented QueueManager.QueueCollection.Queues, where Queue.Active is equal to True.

 HRESULT ActiveQueues(
   [out, retval] VARIANT* pvActiveQueues
 );

pvActiveQueues: A pointer to a VARIANT that, when successfully completed, contains an array of zero or more strings (VT_ARRAY | VT_BSTR) that specify the format names of all the represented QueueManager.QueueCollection.Queues, where Queue.Active is equal to True.

Return Values: The method MUST return S_OK (0x00000000) to indicate success or an implementation-specific error HRESULT on failure.

When the server processes this call, it MUST follow these guidelines:

• If the ComputerName instance variable is NULL:

  • Identify all the local QueueManager.QueueCollection.Queues, where Queue.Active is equal to True.

  • Set the pvActiveQueues output variable to an array that contains the format names that specify all the identified Queues.

• Else:

  • The server MUST generate a QMMgmt Get Info event with the following inputs:

    • iPropID = PROPID_MGMT_MSMQ_ACTIVEQUEUES

  • If the rStatus return value is not equal to MQ_OK (0x00000000), the server MUST return rStatus and MUST take no further action. Otherwise, the pvActiveQueues output variable MUST be set to the value of the returned rPropVar.
