You may use Spy++ or similar application to spy the Messages fired, when a file is opened or a older is opened..
Double click capturing is not an efficient way, as some other applications require their controls to be double clicked too... so, it will be buggy later...
And, also, a file can be opened by right-clicking and choosing Open, or programatically can be opned too... so, better option is to tap the message send by Windows. :)
