Using COM interface to MQSeries

[mqbrowser]

We are about to redesign a VB MQ application to use the MQSeries COM interface. To this point we have added the cmqb.bas file to all our MQ VB applications.

Has anyone had any experience using the COM interface? What is the threading model for this new COM DLL (MQAX200.DLL) that I will reference in my VB project to access MQ? Is it faster? Is it just a wrapper to the old MQMSTD.dll? Are there any special considerations to using this DLL inside a COM component that resides in a COM+ package?

Thanks,

You don't need to add the cmqb.bas file to your projects. This is only needed if you are using the MQI. You are using the COM object model instead, so you just have to include the MQAX200.DLL library in your project's object references.

As far as COM+ goes (or MTS for that matter), no special considerations needed. Just intall the package and make sure you set up the appropriate security on the package (run it under an ID that is a member of the mqm group to make sure it has access to the MQ objects queues, etc.).

There is a manual on IBM's web site on using MQ with MTS..check it out. Scott Meridew
