【SDK编程】LRC歌词制作工具V1.0

今天晚上下载了几个英语听力拷贝到了MP3上听，可是只听看不到原文真是蛋疼，所以想把听力原文做成lrc文件，这样MP3就能显示歌词了。本来想上网上下载个，突然一想这程序也不难，就动手自己写了个，晒下..有BUG，今后会不断改进并添加新功能~

使用方法：
先在your name里输入你的名字，程序会自动在生成的lrc里添加你的信息~
去网上把歌词copy到下面的文本框内，
点openfile找个mp3，然后Current time里显示的就是当前时间，精确到毫秒。
等听到歌唱到那句话的时间，把光标放到那句的前边，点InsertPoint就行啦~
最后别忘了点SaveLRC！
