本程序HOOK的API是DispatchMessageA和DispatchMessageW。在HOOK的方法内会还原ESP，调用user32.DispathMessage(A或W)之后再修改ESP，实现的功能是记录消息的详细日志，记录哪个窗口处理过哪些消息。
1、新建一个win32 console项目，取名为DoInjection，新建一个DoInjectionMain.h，代码如下：
BOOL SetPrivilege(LPCTSTR lPSzPrivilege, BOOL bEnablePrivilege);
BOOL IsVistaOrLater();
BOOL InjectProcess();
BOOL InjectCreateProcess();
void HookGetMessage();
BOOL InjectCreateThread(HANDLE hProcess, LPTHREAD_START_ROUTINE pThreadProc, LPVOID pRemoteBuf);
HANDLE MsicCreateRemoteThread(HANDLE hProcess,LPTHREAD_START_ROUTINE lpStartAddress,LPVOID lpParameter);
typedef void*(__stdcall*LPFN_KernelBaseGetGlobalData)(void);
typedef DWORD (WINAPI *PFNTCREATETHREADEX)
(
PHANDLE ThreadHandle,
ACCESS_MASK DesiredAccess,
LPVOID ObjectAttributes,
HANDLE ProcessHandle,
LPTHREAD_START_ROUTINE lpStartAddress,
LPVOID lpParameter,
BOOL CreateSuspended,
DWORD dwStackSize,
DWORD dw1,
DWORD dw2,
LPVOID Unknown
);
2、新建一个DoInjectionMain.c(不是CPP)，代码如下：
#include <windows.h>
#include <stdio.h>
#include <tlhelp32.h>
#include <tchar.h>
#include "DoInjection.h"
#pragma comment(lib,"th32.lib")

5、新建一个测试程序：WIN32项目，取名为：DoWin32Test，代码如下：

//
#include "stdafx.h"
#include "resource.h"
#define MAX_LOADSTRING 100
// Global Variables:
HINSTANCE hInst; // current instance
TCHAR szTitle[MAX_LOADSTRING]; // The title bar text
TCHAR szWindowClass[MAX_LOADSTRING]; // The title bar text
// Foward declarations of functions included in this code module:

}

}
}

}
//

最后，记得修改所有项目的生成目录，令所有项目生成到一个目录。我设置的方法是直接在默认生成目录前加“..\”。祝你成功。
