申明API、定义常量

 2         {
 3             const int WM_HOTKEY = 0x0312;//如果m.Msg的值为0x0312那么表示用户按下了热键

 6                 case WM_HOTKEY:

 9             }
10             base.WndProc(ref Msg);

接收热键函数

徐淳

 1         int ijk = 0;//标记变量无意义
 2         private void ProcessHotkey(Message m) //按下设定的键时调用该函数        
 3         {
 4             IntPtr id = m.WParam; //IntPtr用于表示指针或句柄的平台特定类型            
 5             //MessageBox.Show(id.ToString()); 
 6             string sid = id.ToString();
 7             switch (sid)
 8             {
 9                 case "100"://热键ID
10                     if (ijk == 0)
11                     {
12                         this.Size = new Size(1, 1);
13                         ijk = 1;
14                     }
15                     else
16                     {
17                         this.Size = new Size(819, 492);
18                         ijk = 0;
19                     }
20                     break;
21             }
22         }

热键调用的函数

　　RegisterHotKey(this.Handle, 100, 2, Keys.D1);-----注册热键

　　RegisterHotKey(本窗口句柄, 热键ID, 第一个键, 第二个键);

　　　　　第一个键：0---null

1---Alt

2---Ctrl

3---Shift

4---Windows

第二个键：Keys.键  Keys可以点出来

PS：热键设为同一个有奇效【手动斜眼】

---

 

　　UnregisterHotKey(this.Handle, 100);-----移除热键

　　UnregisterHotKey(本窗口句柄, 热键ID);
　　PS：一定不要忘了移除啊！！！
