You probably need to also install the XMS package...

| And why can my app be run on my pc installed MQServer if I missed the installation of xms package. It just can not be run in other pcs which just install MQClient and set environment variables. |

You are using WMQ .NET classes and not XMS. So installing XMS IA9H may not solve your problem.
You can't run an .NET application that has been built with MQ v7 assembly on another machine where MQv6 is installed. Type load exception is because, MQDestination.cs class is newly added in WMQ v7 client and it isn't available in v6. So, when the application tried to execute on a computer with v6 client installed. It is trying to look for v7 classes(new) and hence the exception.

Hi all. Any development on this problem.
I don't really understand why this does not work.
Aparently assembly amqmdnet is loaded just fine on system with v6 client (even version is the same in v6 and v7 client). What exacly tries to access MQDestination class? I'm not using it in my app (application is actualy written with v6 client and I'm using v7 only because I moved to Win 7 64-bit).
So, my app written for v6 client (not using MQDestination anywhere) and compiled with v7 client is copied to another machine with v6 client installed. No MQ related files form my machine (that would be from v7) are copied with app. What exacly is using MQDestination?! |

The code you write for V7 is not compatible with the code you write for V6.
The code you compiled with V7 is not compatible with a V6 distribution, even if it does not contain any V7 specific commands.
You need to recompile for the V6 client.
Have fun

MQDestination in MQ v7 is an abstract class. MQQueue and MQTopic classes are derived from MQDestination. So when you compiled with V7 client, MQDestination gets pulled in indirectly even if you have not used it explicitly.
Using .NET book in MQ v7 InfoCenter has more details. |
