In your case, there are two ways:

  1. RPC, the preferred way. the 'other' app should expose RPC API, you the app can invoke and communicate with the 'other' app;
  2. UI Automation, the bad way. You can use Windows API to get a handle of the ComboBox in the 'other' app, and send key stroke event to stimulate human interaction. But it is not reliable. E.g. you cannot lock your screen when the app is running, or you cannot stimulate the action.

you can use a number of technologies.... none are super simple.

  • Sockets
  • MSMQ
  • Named Pipes
  • WCF ( which wraps the three above, and other techniques, can be a bit fiddly to get working)
  • DCOM
  • Windows "SendMessage"
  • Files
  • Shared Memory

You need to learn and use Windows Communication Foundation. Have a look at MSDN article - What Is Windows Communication Foundation?
