Hook键盘解决方法

Hook键盘
我做了一个全局键盘钩子，一个全局钩子DLL和一个应用程序test.exe，当前测试一个简单的功能，屏蔽Alt+F4，现在的现象是这样的：
启动Test.exe，按下Alt+F4，程序不会关闭；打开一个记事本，按下Alt+F4，记事本也不会关闭；不关闭Test.exe，打开资源管理器，按下Alt+F4，资源管理器关掉了！！！这时在对记事本操作，也关闭了，更郁闷的是Test.exe也能关闭。

请大侠们指点一下，我这里贴点代码：

C/C++ code


// HookKeyboard.cpp : Defines the entry point for the DLL application.

#include "stdafx.h"
#include "HookKeyboard.h"
#include <assert.h>

     return  TRUE;

HKB_API LRESULT CALLBACK KeyBoardProc(int code, WPARAM wParam, LPARAM lParam)

    {

    return NULL != glHook;

C/C++ code


#include <Windows.h>

HHOOK g_hOldHook = NULL;

LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam)
{
    if(HC_ACTION == nCode)
    {
        if((GetKeyState(VK_MENU) < 0) && (GetKeyState(VK_F4) < 0))
        {
            return 1;
        }
    }
    return CallNextHookEx(g_hOldHook, nCode, wParam, lParam);
}

int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
    g_hOldHook = SetWindowsHookEx(WH_KEYBOARD_LL, LowLevelKeyboardProc, hInstance, 0);
    if(NULL == g_hOldHook)
    {
        _tprintf(_T("Error: %d\n"), GetLastError());
        return 1;
    }

    MessageBox(NULL, _T("HOOK"), _T("HOOK"), MB_ICONINFORMATION | MB_OK);

    UnhookWindowsHookEx(g_hOldHook);
    return 0;
}

------解决方案--------------------
键盘钩子应该处理不了Alt+F4这些键，用低级键盘钩子试试

我这个可以
