学习通、优课联盟不让粘贴？那就让计算机帮你手打！

前言（不支持中文输入）

这学期英语课用了优课联盟，第一次发现竟然还有不让粘贴的作文？？？但是身为一个半吊子程序员，能偷懒绝不自己动手，这种事情当然直接让计算机来就好了(ノ◕ω◕)ノ

前提

最主要的两个模块就是文件读取和模拟键盘，这样就可以将一个文件打出来了。
新建一个txt文件，保存要粘贴的内容，运行程序，选择文件，准备好了打个ok，读秒开始后三秒内光标点在要打字的地方，so easy!

1.文件读取

首先是弹出文件选择对话框，使用BROWSEINFO
这个解释多一些
然后就是读取文件，使用ifstream，这个就不放链接了，一搜很多解释的

2.模拟键盘

其实就两行

keybd_event("键码",0,0,0);//按下
keybd_event("键码",0,KEYEVENTF_KEYUP,0);//松开

就是和人按键盘一样
通过修改键码，我们就可以让计算机按不同的键
如果是组合键，就像下面这样：

keybd_event("键码1",0,0,0);//按下
keybd_event("键码2",0,0,0);//按下
keybd_event("键码2",0,KEYEVENTF_KEYUP,0);//松开
keybd_event("键码1",0,KEYEVENTF_KEYUP,0);//松开

上完整代码

#include <fstream>
using namespace std;

}
int main()
{OpebFile();Print();return 0;
}

符号不够的话自行搜索键码（keyCode）然后再添加

别问我为什么只有英文，毕竟我只是写英语作文

好吧我承认中文好像很麻烦的样子，应该要加上文字识别，我太菜了不会
