整个程序比较简单，实现方式如下：
1、首先创建对话框和对话框上的控件，然后就是注册热键，因为一旦鼠标自动点击开始，就只能通过键盘组合键来让整个过程停止。特别要注意的是，注册的热键尽量不要和其它程序注册的一样，否则会冲突，冲突后可能会失效，因此注册的越特殊越好。
这里注册了2组热键，CTRL+SHIFT+F4用来锁定或释放鼠标的位置，CTRL+SHIFT+F6用来停止鼠标自动点击的过程。注册的热键要在程序退出时主动调用UnregisterHotKey删除掉。
RegisterHotKey(hWndDlg, WM_MOUSE_POS, MOD_CONTROL | MOD_SHIFT, VK_F4);
RegisterHotKey(hWndDlg, WM_MOUSE_STOP, MOD_CONTROL | MOD_SHIFT, VK_F6);
2、这里使用CreateDialogParam创建非模式对话框，制定自己的消息循环，非模式对话框可以正常接收键盘、鼠标消息。
3、消息及逻辑处理
- 程序启动过后，首先创建定时器，用来实时获取鼠标的位置。
- 处理热键
热键的消息处理逻辑
3、启动按钮处理，启动定时器开始模拟鼠标点击，开始和结束时间的逻辑比较简单暂时没有实现。
通过mouse_event实现模拟鼠标点击，但杀软、防火墙、部分游戏则可能屏蔽mouse_event。这些程序一般会挂接钩子或采用驱动，识别消息到底是不是由外部真正的键盘和鼠标产生的，如果不是会丢弃掉，主要是为了防止记录键盘和鼠标的木马程序。
