How to restart a VCL Delphi application while using a Mutex. This article puts all of the research in one single page.<\/p>\n\n\n\n

Using a mutex prevents multiple application instances from occurring.<\/p>\n\n\n\n

The simplest way is to use your application name and\/or a shorten name that would be unique when creating the mutex<\/a><\/strong> .<\/p>\n\n\n\n
