采用比较容易实现的远程线程注入dll方法, 简单起见实例用MFC完成. 封装了一个CDllInjector类, 可以直接使用
下面的代码就可以实现dll的注入
CDllInjector m_diDllInjector;
m_diDllInjector.OpenProcess(dwProcessId, FALSE) ; // or m_diDllInjector.OpenProcess(szExecName, FALSE)
m_diDllInjector.RemoteVirtualAlloc();
m_diDllInjector.SetInjectDll(strDllName);
m_diDllInjector.SyncInject();
m_diDllInjector.RemoteVirtualFree();
感兴趣的可以看一看

由于现在论坛的附件大小限制的实在太厉害20.48k!!??, 没办法传截图了, 为了减小附件大小传上来, 项目里面也少了一个资源文件DllInjector.ico.自己添加一个就可以编译了.

添加一个资源文件DllInjector.ico后这是vista下的编译结果
