Question about Windows Events

I was talking with an employee the other day and I remember them mentioning a tool that we use that enables you to see what messages the OS sends/receives when an event occurs (for example, when a link is clicked in Internet Explorer (or another browser)).

Can开发者_高级运维 somebody please tell me what this app is called?

It's called Spy++, and it's included with Visual Studio and the Windows SDK.

You can indeed use Spy++ like @SLaks suggested, but if it's specifically to spy on winforms apps (like your tags suggest), I'd recommend Managed Spy. Also from Microsoft and with source code.
