When trying to connect to MQ in bindings mode (I have a server set up locally), I get the following exception:

Quote:
System.TypeInitializationException: The type initializer for 'IBM.WMQ.Nmqi.BindingsNmqiMQ' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.

at IBM.WMQ.MQQueueManager..ctor(String queueManagerName, Hashtable properties)
at Project.MQConnector.CreateConnectAndAddQueueManager(QueueManagerConnectionDetails connDetails)

The error occurs when trying to connect to a queue manager as follows:

Constructor:

Code:
Friend queueManagerConnectionProperties As New Hashtable()
queueManagerConnectionProperties.Add(MQC.THREAD_AFFINITY_PROPERTY, True)
If My.Settings.MQConnectAsClient Then
    queueManagerConnectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT)
Else
    queueManagerConnectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_BINDINGS)
End If

queueManagerConnectionProperties.Add(MQC.CONNECT_OPTIONS_PROPERTY, MQC.MQCNO_HANDLE_SHARE_BLOCK Or MQC.MQCNO_RECONNECT_Q_MGR) ' have handle-sharing with call blocking

And in the CreateConnectAndAddQueueManager method (where connDetails is just a store for the port, host, name, etc.):

Code:
 Dim specificQMConnProperties As Hashtable = CType(queueManagerConnectionProperties.Clone(), Hashtable)
 specificQMConnProperties.Add(MQC.CHANNEL_PROPERTY, connDetails.Channel)
 specificQMConnProperties.Add(MQC.CONNECTION_NAME_PROPERTY, connectionName)
 Dim qmgr As MQQueueManager = Nothing

 Try
     qmgr = New MQQueueManager(connDetails.Name, specificQMConnProperties)
 Catch ex As MQException
     ' error handling
 End Try

I have the following environment variable:

Quote:
NMQ_MQ_LIB=mqm.dll

When I connect using a managed connection (NMQ_MQ_LIB=managed; and don't set the MQC.TRANSPORT_PROPERTY), it works fine.

Any thoughts?
