Webservice using Testand.Engine

[j_dodek]

Hello,

I would like to write a Webservice that monitors my Teststand on demand.

The service should be done in C#

Here is my Question:

Is it possible to access the running Engine ?

greetings

As the TestStand Engine is always loaded only once, there is no expicit method in the API to attach to a running instance, but if you create a new instance of the Engine class, it should be connected to a already running instance of TestStand.

If you ar using TestStand 3.0 or later, you could use the "Application Manager" Object, and call the method "GetEngine" method. this will give you a Refereence to thr running TestStand Engine as well.

Hope this helps!

Hello Andre

Thanks for your reply.

It sounds good. But just one Question.

What is Application Manager Object ? Maybe i am blind but I can not find it in the Teststand 3.5 API

or is it an additional NI-API

Sorry, I forgot to mention that the Application Manager Class is part of the "NI TestStand UI Controls 3.5 (ver 1.0)" Automation Server.

To clarify, what Andre states applies to a single operating system process. There is only one engine per process. If you must access an engine in another process, you must somehow arrange to have a reference to it marshalled to your process. This is the same for the engine as it is for any other activeX object that resides in an external process.
