All,
I am passing Structs back and forth from managed C# to unmanaged raw MCIC32.dll. This code is running concurrently with completely independant COM+ application which is also using the MQIC32.dll via CMQB.bas. The CMQB.bas file is working all the time and is able to retrieve mesages which match the MSGID and CORRELID.
The C# application has worked all the time in a similar development environment but in production environment is not able to find the matching message and returns 2033 ( Timeouts ).
Could this be a problem with differences in the MQ Server ?
Is it possible that CharSet=CharSet.Ansi may not be correct on the Client?
The CLient is Win 2k Advanced server .
The Server is AIX. MQSI is also used in the production env.
Destination system is OS/390.
Anyone have any thoughts.
I have been a single user and found that placing a message on the queue does have the correct Correl ID when I do not use this to retrieve the message.
Thanks,
MD |

| I would suggest using an MQSeries client based trace. This will debug the actual API calls made by MQ and you will be able to see the msgid and/or correlid used. From this, you may be able to eye-ball some data conversion issues .... |

I can validate that the API's are correct because I am getting a 75% success rate. 25% failure rate on messages which are in the queue. Point being this same code works sometimes and does not work others. Is it possible the wrapper which is creating in VB.NET is doing some type of Unicode ( String ) conversion on the C# Wrapper which is entirly in Byte arrays ? This way the 2 byte storage of unicode might cause the some messages to work and other to fail.
Do you know what the MQ Client tool is and where I would find instructions on how it works ? |

I would look at your application a little closer, by looking at the messages
that are retrieved VS those not retrieved, and see what clues come from that.
