不会吧，钩子不是钩系统的吗？和你的对话框有什么关系？
哎......世事总难料我把部分代码写一下.劳烦各位帮我看看:
void CMouseHookDlg::OnCancel() 
{
DlgHwnd=DlgHwndInCMouseHookDlg; //设置标钩子
MouseHook=::SetWindowsHookEx(WH_MOUSE,MouseProc,GetModuleHandle(NULL),0);}
//鼠标钩子回调函数
LRESULT CALLBACK MouseProc(int nCode,WPARAM wParam,LPARAM lParam)
{
if(wParam != WM_MOUSEMOVE) //只处理鼠标移动信息
return (::CallNextHookEx(MouseHook,nCode,wParam,lParam));

MOUSEHOOKSTRUCT* MouseHookStruct; //定义鼠标钩子结构
CPoint  MousePoint;//定义鼠标位置结构
char MousePoint_x[10],MousePoint_y[10];//定义鼠标位置数组

MouseHookStruct  = (MOUSEHOOKSTRUCT*)lParam; //获取鼠标消息

MousePoint.x     = MouseHookStruct->pt.x; //获取鼠标位置
MousePoint.y     = MouseHookStruct->pt.y; _ltoa(MousePoint.x ,MousePoint_x,10); //把鼠标位置转换为字符串
_ltoa(MousePoint.y ,MousePoint_y,10); char MousePointXY[20]; //合并两个字符串到一个字符串中
int  i;
for( i=0; i<10;i++)
MousePointXY[i]=MousePoint_x[i];
for( i=10;i<20;i++)
MousePointXY[i]=MousePoint_y[i-10]; HWND HwndEdit; //获取对话框中EDIT控件的句柄,
HwndEdit=::GetDlgItem (DlgHwnd ,1000);//DlgHwnd为对话框的句柄 //发送鼠标位置字符串到对话框中的EDIT控件中
::SendMessage (HwndEdit,WM_SETTEXT,0,(LPARAM)MousePointXY); //返回
return (::CallNextHookEx (MouseHook,nCode,wParam,lParam));}

Answer 3

OnCancel函数就是开始鼠标钩子的函数

Answer 4

你看一下msdn我记得SetWindowsHookEx函数最后一个参数是设置该钩子是否为系统钩，还是窗口钩的，不妨试一下MouseHook=::SetWindowsHookEx(WH_MOUSE,MouseProc,GetModuleHandle(NULL),1);

Answer 5

SetWindowsHookEx函数最后一个参数是0为系统钩子~
try~
把你的代码贴出来~

Answer 6

//鼠标钩子回调函数
LRESULT CALLBACK MouseProc(int nCode,WPARAM wParam,LPARAM lParam)
{
if(wParam != WM_MOUSEMOVE) //只处理鼠标移动信息
return (::CallNextHookEx (MouseHook,nCode,wParam,lParam));

MOUSEHOOKSTRUCT* MouseHookStruct; //定义鼠标钩子结构
CPoint  MousePoint; //定义鼠标位置结构
char  MousePoint_x[10],MousePoint_y[10]; //定义鼠标位置数组

MouseHookStruct  = (MOUSEHOOKSTRUCT*)lParam; //获取鼠标消息

MousePoint.x     = MouseHookStruct->pt.x; //获取鼠标位置
MousePoint.y     = MouseHookStruct->pt.y; _ltoa(MousePoint.x ,MousePoint_x,10); //把鼠标位置转换为字符串
_ltoa(MousePoint.y ,MousePoint_y,10); char MousePointXY[20]; //合并两个字符串到一个字符串中
int  i;
for( i=0; i<10;i++)
MousePointXY[i]=MousePoint_x[i];
for( i=10;i<20;i++)
MousePointXY[i]=MousePoint_y[i-10]; HWND HwndEdit; //获取对话框中EDIT控件的句柄,
HwndEdit=::GetDlgItem (DlgHwnd ,1000); //DlgHwnd为对话框的句柄 //发送鼠标位置字符串到对话框中的EDIT控件中
::SendMessage (HwndEdit,WM_SETTEXT,0,(LPARAM)MousePointXY); //返回
return (::CallNextHookEx (MouseHook,nCode,wParam,lParam));}//开始鼠标钩子函数
void CMouseHookDlg::OnCancel() 
{
DlgHwnd=DlgHwndInCMouseHookDlg; //设置标钩子
MouseHook=::SetWindowsHookEx(WH_MOUSE,MouseProc,GetModuleHandle(NULL),0);}//关闭鼠标钩子函数
CMouseHookDlg::~CMouseHookDlg()
{
//关闭鼠标钩子
if(MouseHook != NULL)
::UnhookWindowsHookEx (MouseHook);
}

Answer 7

哥，你好象return (::CallNextHookEx (MouseHook,nCode,wParam,lParam));
两次啊，我感觉一次就行了，实在不行你去找本windows核心编程抄抄吧。

Answer 8

你没有把钩子做在dll里面吧？
钩子不在dll里面一般都会有这样的问题

Answer 9

//开始鼠标钩子函数
void CMouseHookDlg::OnCancel() 
{
DlgHwnd=DlgHwndInCMouseHookDlg; //设置标钩子
MouseHook=::SetWindowsHookEx(WH_MOUSE,MouseProc,GetModuleHandle(NULL),0);}
？？？？？？？？
不太对阿~
应该在OnInitDialog里开始吧~
