Overview

Singleinstance contains the basic abstract definition of a class TBaseSingleInstance that, when instantiated, will make sure only 1 instance of your application will be running. It is an abstract instance, you need to instantiate a descendent such as can be found in the advancedsingleinstance unit.

In this document, the first started instance of an application is called the Server, any application started later is called a Client application.

The single instance functionality also provides a mechanism to communicate parameters from the client to the server. For example, an editor started a second time may wish to pass any filenames to be opened to the server instance.
