在win2000中怎么将ctrl+alt+del锁定，能用键盘钩子吗？

[yuanrichard]

我在win2000中将除了ctrl+alt+del的键都锁定了，但是这个键需要用什么方法锁定呢，能用键盘钩子吗？请大家帮忙了，有源码最好

[Jneu]

当然可以！

[roadman]

方法，源代码？谢谢：）

hook dll 代码

#include "stdafx.h"
#include "kbhook.h"
HINSTANCE ghInstance = NULL;
HHOOK m_hook = NULL, g_hook = NULL;
HWND hwnd;


LRESULT WINAPI key_hook(int nCode, WPARAM wParam, LPARAM lParam)
{
if (nCode == HC_ACTION)
{
if (wParam == ((0x5a) & (0x41)))
{
h_stop();
return FALSE;
}
}
if ((::GetKeyState(0x5a)<0) && (::GetKeyState(0x4d)<0))
{
h_stop();
return FALSE;
}
return TRUE;
}


BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
ghInstance = (HINSTANCE)hModule;
break;
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}

BOOL WINAPI h_start()
{
RECT rect;
rect.top = 150;
rect.left = 120;
rect.right = 350;
rect.bottom = 250;
// ::ClipCursor(&rect);
::SystemParametersInfo(SPI_SCREENSAVERRUNNING, TRUE, 0,0);
if (g_hook != NULL)
return FALSE;
g_hook = ::SetWindowsHookEx(WH_KEYBOARD, key_hook, ghInstance,0);
m_hook = ::SetWindowsHookEx(WH_MOUSE, key_hook, ghInstance, 0);
return g_hook != NULL;
}

void WINAPI h_stop()
{
::ClipCursor(NULL);
::SystemParametersInfo(SPI_SCREENSAVERRUNNING, FALSE, 0, 0);
::UnhookWindowsHookEx(g_hook);
::UnhookWindowsHookEx(m_hook);
}



// This is an example of an exported variable
KBHOOK_API int nKbhook=0;

// This is an example of an exported function.
KBHOOK_API int fnKbhook(void)
{
return 42;
}

// This is the constructor of a class that has been exported.
// see kbhook.h for the class definition
CKbhook::CKbhook()
{
return;
}

那其他系统键呢，比如说alt+tab等等，又要怎么处理啊

[yuanrichard]

santaga(食神),我还不是很明白，麻烦你再讲一下好吗

[langjingling]

如果你只是想锁定ctrl+alt+del，那你可以把当前的程序注册为服务器程序就可以啦，这样在当前的任务管理器中就不会再显示出你的程序

[yuanrichard]

我不是想隐藏程序，我是想把键盘锁定，这要怎么做啊，谢谢

[santaga]

g_hook = ::SetWindowsHookEx(WH_KEYBOARD, key_hook, ghInstance,0);
m_hook = ::SetWindowsHookEx(WH_MOUSE, key_hook, ghInstance, 0);
设定鼠标和键盘钩子,全部键盘按键不能使用,鼠标左右键不能使用
LRESULT WINAPI key_hook(int nCode, WPARAM wParam, LPARAM lParam)
{
if (nCode == HC_ACTION)
{
if (wParam == ((0x5a) & (0x41)))
{
h_stop();
return FALSE;
}
}

钩子函数,当输入z m 两个键解除钩子
0x5a 0x41 是z,m的虚拟码

[yuanrichard]

谢谢，但是我还有一点疑问
LRESULT WINAPI KeyboardProc(int nCode,WPARAM wparam,LPARAM lparam)
{
if(gbLock)
return -1;
return CallNextHookEx (glhKeyboardHook, nCode, wparam, lparam);

}
我这样怎么不行啊，gbLock是个布儿值，为什么这样锁定不了ctrl+alt+del,
这有什么区别吗？

埃，真丢人，没看清你的题目原来是在2000下. *^^*

看看这个吧，有代码和文档用互斥做的

[yuanrichard]

santaga(食神)，谢了
终于将ctrl+alt+tab锁定了，但是我发现好像现在我改了mygida.dll以后，F1等键又锁不了了，难道win2000下锁定键盘就这么难么，有那位有比较方便的方法，盼告，定有重酬
