高分求键盘钩子源码
需要可用组合键,例如 CTRL+ALT+Y
讯息的处理在主程序,DLL只处理发送讯息就好

1 声明热键消息处理函数原型
在.h中消息映射声明处(AFX_mSG字样之后)加入如下语句:
LRESULT OnHotKey(WPARAM wParam,LPARAM lParam);
2． 消息与相应处理函数相关联
在.Cpp中加入消息映射宏,使消息与相应处理函数发生关系，
ON_MESSAGE(WM_HOTKEY,OnHotKey);
3． 为方便以后的操作
预先在类中创建一个响应WM_CREATE和WM_DESTROY消息的函数
OnCreate()与OnDestroy()的框架
4．向系统登记热键
在OnCreate()函数中加入如下代码以向系统登记热键,本例子的热键设为
Ctrl＋Shift＋A.
RegisterHotKey(m_hWnd,1001,MOD_CONTROL|MOD_SHIFT,'A');
RegisterHotKey(m_hWnd,1002,MOD_CONTROL|MOD_SHIFT,'a');
5．处理热键
在消息处理函数OnHotKey()中对热键进行处理,并可加入用户希望运行的程序代码
LRESULT C****::OnHotKey(WPARAM wParam,LPARAM lParam)
if(wParam==1001||wParam==1002)
CWnd::SetForegroundWindow();//使得被激活窗口出现在前景
MessageBox("Hello!");
//用户可在此添加代码
return 0;
6．程序运行完毕后解除热键
在OnDestroy()中通过UnRegisterHotKey()解除热键登记,释放系统资源.
UnRegisterHotKey(m_hWnd,1001);
UnRegisterHotKey(m_hWnd,1002);
7．编译并运行程序

下面是实现底层键盘钩子的部分源代码：
LRESULT CALLBACK LowLevelKeyboardProc(int nCode,WPARAM wParam, LPARAM lParam)
{
BOOL fEatKeystroke = FALSE;
If (nCode == HC_ACTION)
{
switch (wParam)
{
case WM_KEYDOWN:
case WM_SYSKEYDOWN:
case WM_KEYUP:
case WM_SYSKEYUP:
PKBDLLHOOKSTRUCT p = (PKBDLLHOOKSTRUCT) lParam;
fEatKeystroke =( (p－>vkCode == VK_TAB)
&&((p－>flags & LLKHF_ALTDOWN) != 0))
||((p－>vkCode == VK_ESCAPE) && ((p－>flags & LLKHF_ALTDOWN) != 0))
||((p－>vkCode == VK_ESCAPE) && ((GetKeyState(VK_CONTROL) & 0x8000) != 0));
break;
}
}
return(fEatKeystroke ? 1 : CallNextHookEx(NULL, nCode, wParam, lParam));
}
int WINAPI WinMain(HINSTANCE hinstExe, HINSTANCE, PTSTR pszCmdLine, int)
{
//安装底层键盘钩子
HHOOK hhkLowLevelKybd = SetWindow
sHookEx(WH_KEYBOARD_LL, LowLevelKeyboardProc, hinstExe, 0);
MessageBox(NULL,TEXT(“Alt＋Esc, Ctrl＋Esc, and Alt＋Tab are now disabled.n”),TEXT(“Click “Ok” to terminate this application and re－enable these keys.”),TEXT(“Disable Low－Level Keys”), MB_OK);
UnhookWindowsHookEx(hhkLowLevelKybd);
return(0);
}
在低于Windows NT 4.0 SP2的NT操作系统下
很遗憾，笔者在低于Windows NT 4.0 SP2或更低版本的NT操作系统下没有找到能屏蔽掉所有的系统热键的方法，本文介绍的方法仅仅可以屏蔽Alt＋Tab和Alt＋Esc。该方法是使用RegisterHotKey函数，在调用该函数后进程会在Alt＋Tab按下时比系统优先一步得到通知。程序员需要处理的消息是WM_HOTKEY。
RegisterHotKey函数原型如下：
BOOL RegisterHotKey(HWND hWnd,int id,UINT fsModifiers,UINT vk);
其中，参数id为自定义的一个ID值，对一个线程来讲其值必需在0x0000～0xBFFF范围之内，对DLL来讲其值必需在0xC000～0xFFFF 范围之内，在同一进程内该值必须唯一；参数fsModifiers指明与热键联合使用的按键，可取值为：MOD_ALT、MOD_CONTROL、MOD_WIN和MOD_SHIFT；参数vk指明热键的虚拟键码。
// 初始化
CMainFrame::CMainFrame()
{
m_nHotKeyID = 100;
BOOL m_isKeyRegistered = RegisterHotKey ;
(GetSafeHwnd(), m_nHotKeyID,MOD_ALT, VK_TAB);
ASSERT(m_isKeyRegistered != FALSE);
}
//取消
CMainFrame::～CMainFrame()
{
BOOL m_iskeyUnregistered = UnregisterHotKey(GetSafeHwnd(), m_nHotKeyID);
ASSERT(m_isKeyUnregistered != FALSE);
}
最后需要在文件中定义ON_MESSAGE消息映射。在头文件中添加如下代码：
class CMainFrame : public XXXX
{
afx_msg LONG OnHotKey(WPARAM wP, LPARAM lP);
}
在CPP文件中的MESSAGE_MAP处添加代码：
ON_MESSAGE(WM_HOTKEY,OnHotKey)
则该热键在进程运行时一直有效，在进程结束后其状态会被系统自动恢复。
