我们先假设一种场景

a.txt文件有100个域名,然后您需要在万网查询这一百个域名是否已经注册,我们的做法一般是:
1、从a文件复制一条域名(CTRL+C)
2、粘贴域名到万网的查询输入框(CTRL+V)
3、不断重复第1步
这种类似的场景大多数人应该都碰到过,如果把第一步省略掉就省事多了,这便是这个工具的由来。

//线程钩子监听鼠标消息设为7,全局钩子监听鼠标消息设为14。lpfn 钩子子程的地址指针。如果dwThreadId参数为0 或是一个由别的进程创建的
//线程的标识,lpfn必须指向DLL中的钩子子程。 除此以外,lpfn可以指向当前进程的一段钩子子程代码。钩子函数的入口地址,当钩子钩到任何
//消息后便调用这个函数。hInstance应用程序实例的句柄。标识包含lpfn所指的子程的DLL。如果threadId 标识当前进程创建的一个线程,而且子
//程代码位于当前进程,hInstance必须为NULL。可以很简单的设定其为本应用程序的实例句柄。threaded 与安装的钩子子程相关联的线程的标识符
//如果为0,钩子子程与所有的线程关联,即为全局钩子
