c++ WH_GETMESSAGE 钩子 ，勾住程序，但是回调函数没执行，请教

需要拦截目标程序的显示和关闭窗口消息。照搬网上的代码。显示注入DLL成功。但是回调函数并没有执行。请教

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
HHOOK hooker;
HWND notepadhandle;
BOOL handled;
extern "C" __declspec(dllexport) LRESULT CALLBACK HookProc(int nCode,WPARAM wParam,LPARAM lParam);
char* ConvertInttoChar(int i);
BOOL APIENTRY DllMain(HANDLE hModule,DWORD ul_reason_for_call,LPVOID lpReserved)
{
    if(ul_reason_for_call==DLL_PROCESS_ATTACH)
    {
        handled=FALSE;
        notepadhandle=FindWindow(TEXT("Notepad"),NULL);

        if(notepadhandle==NULL)
        {
            printf("Notepad Not Found.\n");
            return TRUE;
        }
        hooker=SetWindowsHookEx(WH_GETMESSAGE,HookProc,(HINSTANCE)hModule,GetWindowThreadProcessId(notepadhandle,NULL));
        if(hooker)
        {
            OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE,(DWORD)notepadhandle);
            printf("hookpro:%d\n",HookProc);
            printf("hmodule:%d\n",hModule);
            printf("pid:%d\n",notepadhandle);
            printf("Hook Successfully.\nHookID:%d\n",hooker);
        }
        else
        {
            printf("Hook Failed.\nError:%d\n",GetLastError());
            return TRUE;
        }
        //PostMessage(notepadhandle,WM_CLOSE,0,0);
        //printf("发送关闭指令");

    }

    if(ul_reason_for_call==DLL_PROCESS_DETACH)
    {
        UnhookWindowsHookEx(hooker);
        return TRUE;
    }   
    return TRUE;
}
extern "C" __declspec(dllexport) LRESULT CALLBACK HookProc(int nCode,WPARAM wParam,LPARAM lParam)
{
            printf("NCOD111");
    if(nCode<0)
    {
        printf("NCOD<0");
        return CallNextHookEx(hooker,nCode,wParam,lParam);
    }
    tagMSG* msg;
    msg=(tagMSG*)lParam;
    if(nCode==HC_ACTION && (msg->message==WM_CLOSE))
    {
        if(handled==FALSE)
            printf("拦截到消息:%d\n",msg->message);
        handled=TRUE;
        UnhookWindowsHookEx(hooker);
        msg->message=WM_NULL;

        return CallNextHookEx(hooker,nCode,wParam,(LPARAM)msg);
    }
            printf("LAST");
    return CallNextHookEx(hooker,nCode,wParam,lParam);
}

执行的结果，DLLmain的代码能正常执行，并显示注入成功；但是回调函数中的打印代码均没执行，请教。
执行结果
hookpro:1666846815
hmodule:1666777088
pid:4063406
Hook Successfully.
HookID:17567643

你应该用全局钩子，第四个参数用0

dwThreadId [in]
Type: DWORD
The identifier of the thread with which the hook procedure is to be associated. For desktop apps, if this parameter is zero, the hook procedure is associated with all existing threads running in the same desktop as the calling thread. For Windows Store apps, see the Remarks section.

hooker=SetWindowsHookEx(WH_GETMESSAGE,HookProc,(HINSTANCE)hModule,0);

继续求人帮忙解决，

你获取的线程ID不对，貌似那个函数不行，你可以用工具查看一下你程序获得的跟工具获得的是否一样
