How to bring calc.exe to front?

Question

I have the following code assigned to a VAIO button:

C:\Windows\System32\calc.exe

But each time I press the VAIO button I get a new instance of the calculator in a new window. What would be the command line that brings the calculator to front if there is already a window of it?

BTW: I tried the following, but it didn't work. It just behaves as the VAIO button:

start /B calc       # doesn't work

Best Regards

Solution

The batch-file to check if calc.exe is already started doesn't have to be as elaborate as uprego stated.

But first... Do you really want to switch to the current calc.exe? Or do you just want one calc.exe running. If you don't need to switch to the current one you can just make a batch-file which kills the first and runs a new instance of calc.exe:

calc.bat:

@echo off
taskkill /f /im "calc.exe"
start calc.exe

Only downside is you loose the current result in your previous calculation.

If you don't want the current calc.exe to be killed there are also solutions to bring it to the front (but they will be somewhat more complicated). Let me know if you really want to switch to the current calc.exe and i'll try to do some further searching.
