封装远程注入类CreateRemoteThreadEx

类初始化时传入要注入的DLL文件名

只使用两个函数

// 注入DLL到指定的地址空间
BOOL InjectModuleInto(DWORD dwProcessId);
// 从指定的地址空间卸载DLL
BOOL EjectModuleFrom(DWORD dwProcessId);

.h

#pragma once#include <windows.h>  //在头文件中包含class CRemThreadInject{public:CRemThreadInject(LPSTR lpDllName);~CRemThreadInject(void);protected:char m_szDllName[MAX_PATH];static BOOL EnableDebugPrivilege(BOOL bEnable);public:// 注入DLL到指定的地址空间BOOL InjectModuleInto(DWORD dwProcessId);// 从指定的地址空间卸载DLLBOOL EjectModuleFrom(DWORD dwProcessId);};
