I have an application and from this application I have to start another process by shutting down the current application and after the completion of the process again start the application. The flow is as follows, suppose I have an application app.exe, and another application another.exe, so i have to do following:

1) Start app.exe

2) Stop/shutdown app.exe and start another.exe from app.exe

3) When another.exe completes, stop/shutdown another.exe and start app.exe from another.exe

Anyone please provide me some clue of how to do it ?
