1If you're pulling those stunts with PowerShell just go ahead and write a "real" C# Program. it's going to be less of a headache and using Visual Studio would mean you would have a lot of GUI help for a lot of things (IntelliSense etc.). What you would need to do is bind to the event for the buttons and let the function you bind to the event change the text for the input. – Seth – 2017-01-21T15:24:46.593

The following improvement of my previous answer to your almost the same question could help however such patchwork would conduce you to perdition (as well as me). Good luck!

$script:PartialResult = ''

Hello JosefZ thanks for your answer. Could you explain me what the Funtion Operation exactly is doing? – Sandro21 – 2017-01-22T11:43:46.487
