The problem with VB is that you can't store pointers to functions and then call them in the same way you can from C.
You could write a small DLL in C that provides the MQCONN etc. entry points and then calls the actual entry points in mqm.dll or mqic.dll based on the discussion below.

We do this on both NT, AIX and Solaris platforms. You need to look at www.mqseries.net and do a search in the software repository for either "ntloadmq", "sunloadmq" and "slloadmq" (for AIX). These will give you ideas on how to dynamically load the MQ libraries. Basically, the extension I did to this was to try and load the mqserver library first. If that fails, drop down and look for mqclient. If that fails it's game over. Hope this helps.

My understanding is that the code can be written such that no changes are needed and the method of connection (Client or Server) depends upon which set of MQSeries libraries the program links with. This would create two different executable, one for a MQSeries Client system and another for a MQSeries Server system Is there a way to create a single executable which will recognize it is on a MQSeries server and perform accordingly and if not, perform as if it were running on a MQSeries client system?
