FIX: Cannot Read Messages from MSMQ-MQSeries Bridge Dead Letter Queue (281515)


The information in this article applies to:

  • MSMQ - MQSeries Bridge
  • Microsoft SNA Server 4.0 SP3
  • Microsoft SNA Server 4.0 SP4
This article was previously published under Q281515

SYMPTOMS

A program that is written in Microsoft Visual Basic may not be able to read Message Queuing messages that have been rejected and stored in the MSMQ-MQSeries Bridge Dead Letter queue.

CAUSE

When MQSeries rejects a message whose message body contains a Component Object Model (COM) object, the MSMQ-MQSeries Bridge changes the value of the PROPID_M_BODY_TYPE property to VT_BLOB (instead of maintaining the original variant type that is assigned to PROPID_M_BODY_TYPE). As a result, Visual Basic applications cannot read the message from the Dead Letter queues because VT_BLOB is not a known variant type.
