I am trying to migrate my vb6 code to vb .net and I am having some difficulty. Has anyone converted the sample apps amqsgetb and amqsputb? If so, where can I get them?
I have already successfully used MQAX200 in vb .net, but my boss wants me to do performance testing with the api calls vs. MQAX200. Do you know if using MQAX200 will be slower than using the api calls?
Thanks,
Gary |

Is there somewhere I can get sampble vb .net code that doesn't use your MQSeries.net package or MQAX200?
Thanks,

Im not entirely sure but am 90% sure that VB.NET cannot access code outside the CLR(common language runtime). It can only access COM components(such as MQAX200.dll) because of the COM Interop functionality built into .NET. Other then COM interop, any code that VB.NET calls must run under managed code. Calling out to the MQ API would be impossible.
You can however do this with c#. But why do yourself, when its already been done It would involve wrapping the MQ C++ API which has some large structs and take a good deal of time. _________________ Bobby Ledford
