Saber 酱的抱枕

很久没发东西了……
嘛最近那什么感觉还不错……
算了不扯远

承载网络是win7下引入的共享网络的方法。事实上网上教程多如牛毛，相关软件也不少
下面是我的教程（没错，就是很久以前写的那个）及其辅助工具。
注意，由于只是辅助工具，有些步骤难以代劳，所以不对这个方法有个全面的了解直接用工具只会摸不着头脑

工具可以直接查看代码……对密码位数处理的代码来自网络

http://pan.baidu.com/s/1sjv0WIL

net share.exe
大小 ：240,128字节
MD5：7bbf66beef3af7c3e98d40054bb083f1
SHA1：5f76a27775a32076deae8434a6ddb7017b9f52ca
CRC32：46193bad

bat大更新，增强了代码健壮性，允许ssid和密码输入空格等字符事实上字符串处理一塌糊涂………………

c++版本正在路上。基础功能已经完成。 完成。
部分功能直接使用api调用，并且c++下字符串处理再怎么着也比批处理方便
有些仍然保留netsh，是因为不知道api/api没有公开/使用api会导致程序结束共享即关闭
API参考：https://msdn.microsoft.com/en-us/library/ms706274(v=vs.85).aspx
然而代码及其粗糙，完全不适合debug。反正也就自己随便用用……好孩子不要学!!!缩进已经爆炸了我不管了
