Using Windows calculator

Hi there,

To use the calculator from Windows, I use the following line:

ShellExecute(0,nil,pchar('C:\WINDOWS\CALC.EXE'),nil,nil,sw_shownormal);

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!

or use classname instead of caption as this should be same for all languages:

HCalc := FindWindow( SciCalc,nil);

Hi Cesario,

Your solution is working fine, however, I would like to implement your example in my application without changing it everytime when my users are using different languages.

So, if you can send me a solution to solve that issue I would be very happy. But it's not required, because this is already working for me.

Your colleague wrote something like HCalc := FindWindow(SciCalc,nil), but this is not working (error message).

Thank you anyway.
