Programmatically launch 32bit or 64bit TS from C#

[MisterVVC]

Hi,

I'm using the simple C#.net example to run TS sequences. I have both 32bit & 64bit TS 2019 installed.

I can use the TS version selector to launch either versions but I want to control the launch from within C#. How do I do this using the "LaunchTestStandApplicationInNewDomain.LaunchProtected(.......). Can I pass a particular argument to it that alters what TS instance is invoked.

Thanks,

The TestStand Engine is a per-process singleton, so it will be the same bitness as your C# app. If you want to run sequences in both bitnesses, i can think of a few options:

• Compile your app for both bitnesses and make a launcher app that decides what version to launch
• Create your app in one bitness and use remote executions to call cross-bitness sequences externally:

• Spawn off a new process and communicate with that from your app (similar to above but more complicated)

Hope this helps!

Thanks for the info - I finally got round to trying this out by compiling a 32bit & 64bit C# app and running the relevant sequences. This proved TestStand bitness is as per your description.
