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

@MartinJames you could have been more helpful and suggested where I should start looking as written in the question.. — Haz, Aug 17 '14 at 10:35

Arduino is a open-source hardware and supporting software project that you should be aware of. It's typically programmed in C or C++, but see "How to Communicate to the Arduino in Visual Basic .NET".

You might also pick up some good ideas from "How to Hack a Doorbell and Connect it to Twitter".

Finally, don't miss the Arduino StackExchange.

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
