Recording / playback of messages

Hi, I am writing an educational application that will also be used for research purposes. As such it needs to record the user's actions. I am hoping to be able to replay these actions exactly so a researcher can examine what the user did and where they went wrong. This means mouse movements, clicks and what they typed etc. I come from a C++, Win32 background and am just learning C#. My first thought was to trap messages sent by Windows and then send them back later. I wonder if this would work or if there is another easy way?

thanks in advance
