Creating a single instance application

We may sometimes want to limit the number of running instances of some application to just one. Running some executable creates a new Windows process to host that executable, with its own address space, tables, resources, and so on. Sometimes this is not desirable; if the executable tries to run while another instance is already running, it should quit and optionally make the other instance's main window active. A canonical example in Windows is Windows Media Player. An attempt to open a second media player activates the first Media Player window (although it's debatable whether such behavior is desired for Media Player).

Let's see how this can be achieved.
