如何把exe文件读到内存中直接运行

[caicaileowince]

我有一个exe文件，想把它放到另一个exe文件的资源里，运行时候直接把这个exe考到内存中然后运行
试了网上找的方法都没成功，大家有能用的代码吗谢谢分享

我从网上找的方法是
http://www.bitscn.com/hack/safe/200607/48139.html
试了不行，可能是哪些参数设置错了

[ibican]

300块钱不好挣啊

[caicaileowince]

大家有这方面资料吗

[空心兜兜]

只知道库文件可以...

[ibican]

我试了试 那个例子能用

编译后可以成功使用，但卡巴报毒 如果你做这个东西要给别人用 另想它法吧

[caicaileowince]

楼上这位大哥，你成功把exe调起来没有？我这怎么试了不行呀
