Q: 

How to block execution of same exe file already running?

I'm building client/server apllication on QT. I just want user to execute only one application per a machine. I've heard MUTEX can be used for those kind of situation. Does anyone get some tips on MUTEX or anything else? Thanks.

+2  A: 

Try QtSingleApplication: http://qt.nokia.com/products/appdev/add-on-products/catalog/4/Utilities/qtsingleapplication - works fairly well.

QtSingleApplication also let's you send messages to the running instance.
