I am developing an application that monitor activities on XP/win2k machine. It is a simple application that calculates total idle time and active time and produces a report daily. The machine is considered idle if there's no keyboard or mouse movement.
What's the best way to do the above ? I am trying a method that detects keyboard and mouse activities, basically capturing windows event such as WM_KEYUP, WM_LBUTTONDBLCLK, etc.. My question is how reliable this method is ? I am using SetWindowsHookEx API call to intercept the windows messages.
