title: Global mouse hook in C# application
body: <p>I want to create an application that starts some action when the user clicks on a specified button of a third-party windows application. I have already read here: <a href="https://stackoverflow.com/questions/54746218/global-mouse-capture-in-c-sharp-application#comment96274472_54746218">Global mouse capture in C# application</a> so I am able to detect when an application is launched or closed. 
  The issue that stops me to implement what I want is that I am not able to know when the user clicks on a button.</p>
