想用WH_CBT钩子实现已注册窗口子类化，执行却总是报错，贴上代码，请教怎么回事

FUNCTION: MyRegisterClass()
PURPOSE: Registers the window class.
This function and its usage are only necessary if you want this code
to be compatible with Win32 systems prior to the 'RegisterClassEx'
function that was added to Windows 95. It is important to call this function
so that the application will get 'well formed' small icons associated
ATOM MyRegisterClass(HINSTANCE hInstance)
WNDCLASSEX
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style
= CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = CExWnd::WindowP
wcex.cbClsExtra
wcex.cbWndExtra
wcex.hInstance
wcex.hIcon
= LoadIcon(hInstance, MAKEINTRESOURCE(IDI_T1));
wcex.hCursor
= LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName = MAKEINTRESOURCE(IDC_T1);
wcex.lpszClassName = szWindowC
wcex.hIconSm
= LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_SMALL));
return RegisterClassEx(&wcex);
FUNCTION: InitInstance(HINSTANCE, int)
PURPOSE: Saves instance handle and creates main window
In this function, we save the instance handle in a global variable and
create and display the main program window.
LRESULT CALLBACK QWndCbtProc(int nCode,WPARAM wParam,LPARAM lParam){
if(nCode!=HCBT_CREATEWND)
return ::CallNextHookEx(gHook,nCode,wParam,lParam);

&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& //此处钩子异常，不知道怎么回事
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& pWnd-&m_lpfnOldWndProc=(WNDPROC)::GetWindowLong(hWnd,GWL_WNDPROC);
assert(pWnd-&m_lpfnOldWndProc);
if(pWnd-&m_lpfnOldWndProc!=CExWnd::WindowProc){
::SetWindowLong(hWnd,GWL_WNDPROC,(LONG)CExWnd::WindowProc);
return ::CallNextHookEx(gHook,nCode,wParam,lParam);
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
hInst = hI // Store instance handle in our global variable
hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance,pE);
//安装钩子
if(gHook==NULL){
gHook=::SetWindowsHookEx(WH_CBT,QWndCbtProc,hInstance,::GetCurrentThreadId());
if (!hWnd){
return FALSE;
ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
return TRUE;
FUNCTION: WndProc(HWND, UINT, WPARAM, LPARAM)
Processes messages for the main window.
WM_COMMAND - process the application menu
WM_PAINT - Paint the main window
WM_DESTROY - post a quit message and return
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
int wmId, wmE
PAINTSTRUCT
switch (message)
case WM_COMMAND:
= LOWORD(wParam);
wmEvent = HIWORD(wParam);
// Parse the menu selections:
switch (wmId)
case IDM_ABOUT:
DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);
case IDM_EXIT:
DestroyWindow(hWnd);
return DefWindowProc(hWnd, message, wParam, lParam);
case WM_PAINT:
hdc = BeginPaint(hWnd, &ps);
// TODO: Add any drawing code here...
EndPaint(hWnd, &ps);
case WM_DESTROY:
PostQuitMessage(0);
return DefWindowProc(hWnd, message, wParam, lParam);
// Message handler for about box.
INT_PTR CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
UNREFERENCED_PARAMETER(lParam);
switch (message)
case WM_INITDIALOG:
return (INT_PTR)TRUE;
case WM_COMMAND:
if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL)
EndDialog(hDlg, LOWORD(wParam));
return (INT_PTR)TRUE;
return (INT_PTR)FALSE;

X:\Program Files\Internet Download Manager 删除IDMGrHlp.exe
X:\Program Files\Internet Download Manager目录下建 “新建文本文档.txt” 改名IDMGrHlp.exe
别忘了把IDMGrHlp.exe右击-属性-设为只读........
重启idm就ok了！
注：X:\Program Files\Internet Download Manager为idm安装目录.

如弹窗所示，缺少文件，请重装IDM
缺少1文件，请您重新安装此产品（IDM）
卸载后重新安装吧。
这是某会员提供的Internet Download Manager 6.07 build 14破解版
版区有你更精彩： ）
卸载重装~~
重装了，现在明白了。原来是用数字优化时清理了一个插件

我这个菜鸟我都瞧出来了，需要重装，应该楼主用的是破解版本，然后更新导致的吧
我用下载助手
