To use the calculator from Windows, I use the following line:
This is working fine...
Now I have the following question: Before I execute this calculator I want to check if there is already an instance active. And if there is already a calculator active then I would like to set the focus on that one. In other words: not opening a new instance anymore. If minimized then (of course) I would like to maximize before setting the focus on the calculator.
Please provide me with a complete example.
Thank you very much!
