C # RegHotKey class. It is easier to write window programs and register global hotkeys.

C # it is inconvenient to operate winApi. For example, without pointers, It is a headache.

In the past two days, you need to write a program to register the global hotkey, So you wrote this class. Registering hotkeys is easier.

The call is very simple:

Hk = new HotKey ();
Hk. RegHotKey (Keys. End, fun); // The method name is the 2nd parameter.

Hk. UnRegHotKey (Keys. End); // cancel the hotkey
