How to run calc.exe in OMI?

Hello Zhen!

You could try the following:

System.Diagnostics.Process.Start("calc");

It will start an instance of calculator in a external window.
If your aiming for starting a calculator within your OMI Application, i.e in a pane, you need to use something from third party vendor, (.Net or a Web Widget) or spend some time creating a Industrial Graphic Symbol.
There are some parameters that you can input as well if required.
