问：如何实现“单击鼠标左键，等效于使键盘上的F7被按下一次”？

Question

当单击鼠标左键,向系统发消息.SendMessage(WM_KEYDOWN,VK_F7,0)好想是这样吧.

Answer 1

SendMessage（）有四个参数，第一个是句柄，用WM_KEYDOWN 能行吗？

Answer 2

     switch (message)
     {
     ......
     case WM_LBUTTONDOWN: 
 keybd_event( VK_F7,
                      0x45,
                      KEYEVENTF_EXTENDEDKEY | 0,
                      0 );
 keybd_event( VK_F7,
                      0x45,
                      KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
                      0);
      
 
 return 0;
     ......
     }
