Hello Every Body How can I handle a system event that is not exposed by the SystemEvents class using c# ? I read somthing about "InvokeOnEventsThread" method in MSDN : public static void InvokeOnEventsThread(Delegate method); But I don't undrestand how I can use it.Please Help Me. Thanx :confused:

What are you calling a "system event"? What "event" are you looking to a notification of? RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

Hi... I want to handle system events such as mouse clicks,mouse move and any action that happens out side of my application(When my application is not focused.Such as clicks on desktop or on any other application). Like babylone dictionary and keyloggers.I read an article in code project about system hooks(Global System Hooks in .NET) But hooking is very heavy action.The CPU usage of this sample is 80% to 100% when application is running ! I want a way to trap this events when they happen. Please Guide me !

The only way to grab the mouse and keyboard events are global system hooks. If written properly, the hooks will not consume any measurable CPU time for days, maybe even weeks. But, of course, this all depends on what your doing with the captured messages. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome
