How to handle and event from pushing a physical button?

Question

Hello I am creating an application on vb.net which I want to launch an event whenever someone rings the doorbell. Can someone show me where I need to start looking? I know I need a circuit, but it should be very simple since I only want to push a button. Thanks

An interesting hardware question. My solution here without additional hardware/circuit.

• Install Microsoft Speech SDK.
• Configure your MIC to listen to your doorbell.

• In your code, on distinguishing the doorbell, invoke a button click in your screen. See below code to invoke a button:

  'Imports System.Windows.Automation.Peers
  'Imports System.Windows.Automation.Provider
  If SpeechObject(DetectDoorBellRing) = True Then
      Dim peer As New ButtonAutomationPeer(btnExecute)
      Dim invokeProv As IInvokeProvider = TryCast(peer.GetPattern(PatternInterface.Invoke), IInvokeProvider)
      invokeProv.Invoke()
  End If
