Sample of Google Chrome Native Messaging
Source Code: https://github.com/Mandar-Shinde/Google-Chrome-Native-Messaging
Extensions and apps can exchange messages with native applications using an API that is similar to the other message passing APIs. Native applications that support this feature must register a native messaging host that knows how to communicate with the extension. Chrome starts the host in a separate process and communicates with it using standard input and standard output streams.
