子類化：
 // 保存窗口默認的消息響應函數(shù)指針
WNDPROC pSubclassOldEditProc;
// 用于替換子類化窗口的消息響應函數(shù)
LRESULT CALLBACK JcEditProcSubClass(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
   {
 switch(message)
   {
case WM_CHAR:
{
::MessageBox(hWnd, "WM_CHAR響應", "子類化", MB_OK);
return 0;
}
default: return ::CallWindowProc(pSubclassOldEditProc, hWnd, message, wParam, lParam);
}
}
// 對創(chuàng)建好的窗體進行子類化代碼
{
// 創(chuàng)建
HWND hEdit = CreateWindowEx(NULL, "EDIT", "SubClass",
WS_CHILD|WS_BORDER|ES_LEFT|ES_AUTOHSCROLL, 100,120, 128, 16, hWnd, NULL, hInstance, NULL);
pSubclassOldEditProc = (WNDPROC)::SetWindowLong(hEdit, GWL_WNDPROC, (DWORD)JcEditProcSubClass);
// 顯示
ShowWindow(hEdit, nCmdShow);
UpdateWindow(hWnd);
}
超類化：
WNDPROC pSuperOldEditProc;// 保存窗口默認消息處理函數(shù)
// 用于替換的超類化消息響應函數(shù)
LRESULT CALLBACK JcEditProcSuper(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch(message)
{
case WM_CHAR:
{
::MessageBox(hWnd, "WM_CHAR響應", "超類化", MB_OK);
return 0;
}
default: return ::CallWindowProc(pSuperOldEditProc, hWnd, message, wParam, lParam);
}
}
// 創(chuàng)建超類化控件代碼
{
// 取得原控件信息
WNDCLASSEX myeditClass;
::GetClassInfoEx(hInstance, "EDIT", &myeditClass);
// 保存原控件默認消息處理函數(shù)
pSuperOldEditProc = myeditClass.lpfnWndProc;
// 設置替換的消息處理函數(shù)
myeditClass.lpfnWndProc = JcEditProcSuper;
// 指定新的窗口類名字
myeditClass.lpszClassName = "JcilyEdit";
// 設置結構體大小
myeditClass.cbSize = sizeof(WNDCLASSEX);
// 注冊新信息
RegisterClassEx(&myeditClass);
// 創(chuàng)建
HWND hEdit = CreateWindowEx(NULL, myeditClass.lpszClassName, "SuperClass",
WS_CHILD|WS_BORDER|ES_LEFT|ES_AUTOHSCROLL, 100,100, 128, 16, hWnd, NULL, hInstance, NULL);
// 顯示
ShowWindow(hEdit, nCmdShow);
UpdateWindow(hWnd);
