First of all B.exe must fit the rules of a service - not every executable can run as service!!!
I would also advise to make B.exe a self installing service, so you can start and stop it from a single command line...
There are samples for such services:
Windows Services Can Install Themselves[^]
Windows Service to Host Multiple WCF Services[^]

At first you have to install the service. To start a service programmatically use the OpenService function (Windows)[^] and the StartService function (Windows)[^]. Note that this requires that the program is executed with sufficient priviliges.

Alternatively use the Windows PowerShell (execute shell commands from your program). See Start-Service[^].

The general term for data interchange between processes is IPC (Interprocess Communications (Windows)[^]). You should read about the available methods and choose one that matches your requirements. The CodeProject article Windows IPC[^] explains some methods in detail with their advantages and disadvantages and provides example code.
