VB变态应用之“移花接木”

azi6691 · 发表于 2014-8-28 12:05:23

今天可是个好日子啊~~就在这个好日子送给我们广大的程序大朋友们和小朋友们一个节日礼物，同时我也希望这份代码能给带来一些思路和技术上的提升，但是更希望大家能用到正途上不要搞歪门邪道。此代码的功能比较强悍，所以用到好的地方自然能发光，但是用到黑暗的地方可能会辱没了这份代码，希望大家认真对待这份珍贵的代码，我是专门花了一天时间写的，而且专门用VB语言写的，其实用C的话更简单更快，就是想在节日送给我们广大的VB爱好者一个节日礼物。在这里祝大家“节日快乐”~哈哈~~

想了很久也不知道怎么为这份代码（文章）取个好听的名字想来想去好像“移花接木”最适合。为什么这么说呢？这份代码可以完成远程调用，可以在远程进程中执行任何STDCALL声明的API函数，这样做到了“远程调用本地化”当然还没达到这种级别的效果，但是确实还是值得我们继续在这份代码上发展和研究。我在测试程序中写了三个典型的实例。首先是一个在远程进程中弹出一个消息框的测试（这里要保证目标进程已经加载了USER33.DLL才行）。第二个实例是演示了利用远程进程创建新进程的功能（在这里我想说点废话，我在我博客也发表了好几种创建SYSTEM进程的代码，当然有参考别人的代码和思路，以前也有人说过用远程注入的方式实现，但是好像是需要DLL的好了现在这份代码不再需要DLL而且你可以创建指定用户的进程,比如你可以创建SYSTEM用户甚至是LOAL SYSTEM用户等）。第三个实例是演示了NT系列函数的调用也是演示了参数带返回值的API函数在我的程序中的调用方法和取返回值的方法。其实还有很多很多的功能有待大家去研究琢磨我只是提供了一个小小的“平台”，希望大家在这个“平台”给你带来更多的精细也希望能使大家更深入的了解VB内嵌汇编的方法和需要注意些什么。我在这份代码上做了详细的注释，如果你在使用还有不明白的地方或者发现存在了某些BUG请于我一起探讨，谢谢。好了废话就不多说了大家等得都是代码。
