以前用masm写的 小远程控制 也搬过来
看看就好初学汇编的时候写的
最先是在看雪发的新开空间我也没啥东西 只能拿这个凑数了
;作者：落笔飞花笑百生
;日期：2014/12/20
;用处：练手
;写一个程序虽然很烂但是确实能学到很多，用汇编写程序能逼迫自己去学习以前高级语言中容易忽略的东西虽然还是不够。
;但是至少脱离了只能用别人封装好的库来写程序的恶性循环
;这个程序也没有了写下去的意思，该解决的都解决了我实在想不出来再写他具体能得到什么
;本来想把自己实现的getFUNCaddress加进去的，也没有这样做。
;DLL名称和函数名称由于直接这样写会被某些弱智杀软杀字符串没办法只能xor简单加密一下然后取地址再动态解密一下 这样过了表面
;二次开发的人注意:xor第一个字符不加密的
