请问高手：(200分）调试著名的画红色R钩子程序时，说m_hook.start未定义。郁闷。
(1)．选择MFC AppWizard(DLL)创建项目ActiveKey，并选择MFC Extension DLL（共享MFC拷贝）类型（中文版第3项）。
(2).插入新文件ActiveKey.h，在其中输入如下代码：
#ifndef _KEYDLL_H
#define _KEYDLL_H
class AFX_EXT_CLASS CKeyHook:public CObject
{
public:
CKeyHook();
~CKeyHook();
HHOOK Start(); //安装钩子
BOOL Stop(); //卸载钩子
};
#endif
(3).在ActiveKey.cpp文件中加入声明＂#include ActiveKey.h＂。
(4).在ActiveKey.cpp文件中加入共享数据段，代码如下：
//Shared data section
#pragma data_seg("sharedata")
HHOOK glhHook=NULL; //钩子句柄。
HINSTANCE glhInstance=NULL; //DLL实例句柄。
#pragma data_seg()
(5).在ActiveKey.def文件中设置共享数据段属性，代码如下：
SETCTIONS
shareddata READ WRITE SHARED
(6).在ActiveKey.cpp文件中加入CkeyHook类的实现代码和钩子函数代码：
//键盘钩子处理函数。
extern "C" LRESULT WINAPI KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam)
{
if( nCode >= 0 )
{
if( wParam == 0X79 )//当按下F10键时，激活外挂。
{
//外挂实现代码。
CPoint newPoint,oldPoint;
GetCursorPos(&oldPoint);
newPoint.x = oldPoint.x+40;
newPoint.y = oldPoint.y+10;
SetCursorPos(newPoint.x,newPoint.y);
mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);//模拟按下鼠标左键。
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);//模拟放开鼠标左键。
keybd_event(VK_SHIFT,MapVirtualKey(VK_SHIFT,0),0,0); //按下SHIFT键。
keybd_event(0x52,MapVirtualKey(0x52,0),0,0);//按下R键。
keybd_event(0x52,MapVirtualKey(0x52,0),KEYEVENTF_KEYUP,0);//放开R键。
keybd_event(VK_SHIFT,MapVirtualKey(VK_SHIFT,0),KEYEVENTF_KEYUP,0);//放开SHIFT键。
SetCursorPos(oldPoint.x,oldPoint.y);
}
}
return CallNextHookEx(glhHook,nCode,wParam,lParam);
}
CKeyHook::CKeyHook(){}
CKeyHook::~CKeyHook()
{
if( glhHook )
Stop();
}
//安装全局钩子。
HHOOK CKeyHook::Start()
{
glhHook = SetWindowsHookEx(WH_KEYBOARD,KeyboardProc,glhInstance,0);//设置键盘钩子。
return glhHook;
}
//卸载全局钩子。
BOOL CKeyHook::Stop()
{
BOOL bResult = TRUE;
if( glhHook )
bResult = UnhookWindowsHookEx(glhHook);//卸载键盘钩子。
return bResult;
}
(7).修改DllMain函数，代码如下：
extern "C" int APIENTRY
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
//如果使用lpReserved参数则删除下面这行
UNREFERENCED_PARAMETER(lpReserved);
if (dwReason == DLL_PROCESS_ATTACH)
{
TRACE0("NOtePadHOOK.DLL Initializing!\n");
//扩展DLL仅初始化一次
if (!AfxInitExtensionModule(ActiveKeyDLL, hInstance))
return 0;
new CDynLinkLibrary(ActiveKeyDLL);
//把DLL加入动态MFC类库中
glhInstance = hInstance;
//插入保存DLL实例句柄
}
else if (dwReason == DLL_PROCESS_DETACH)
{
TRACE0("NotePadHOOK.DLL Terminating!\n");
//终止这个链接库前调用它
AfxTermExtensionModule(ActiveKeyDLL);
}
return 1;
}
(8).编译项目ActiveKey，生成ActiveKey.DLL和ActiveKey.lib。
接着，我们还需要创建一个外壳程序将全局钩子安装了Windows系统中，这个外壳程序编写步骤如下：
(1).创建一个对话框模式的应用程序，项目名为Simulate。
(2).在主对话框中加入一个按钮，使用ClassWizard为其创建CLICK事件。
(3).将ActiveKey项目Debug目录下的ActiveKey.DLL和ActiveKey.lib拷贝到Simulate项目目录下。
(4).从“工程”菜单中选择“设置”，弹出Project Setting对话框，选择Link标签，在“对象/库模块”中输入ActiveKey.lib。
(5).将ActiveKey项目中的ActiveKey.h头文件加入到Simulate项目中，并在Stdafx.h中加入#include ActiveKey.h。
(6).在按钮单击事件函数输入如下代码：
void CSimulateDlg::OnButton1()
{
// TODO: Add your control notification handler code here
if( !bSetup )
{
m_hook.Start();//激活全局钩子。
}
else
{
m_hook.Stop();//撤消全局钩子。
}
bSetup = !bSetup;
}

这么多代码，实际上问题可能不是代码导致的。
看起来，应该是你的头文件包含的次序和位置出了问题，你可以尝试着变化ActiveKey.h的包含位置，假如问题依然存在，那么把工程发给我来看看，fzd999@jxfw.comTop
