实现令人满意的风格统一的软件界面确实很难,　象网友提到的MessageBox、FileDialog、FontDialog、目录选择对话框等MFC内部甚至系统DLL内的对话框，要想让它变脸可不容易。有人说HOOK技术可以，HOOK技术确实可以，HOOK可以说是无孔不入，但HOOK的使用效率却是令人难以满意的，从目前大多数采HOOK技术的换肤软件使用情况来看，完全可以证明这一点。今天我们将讨论另外一技术来实现FileDialog的变脸，这种技术叫替换窗口过程法（注：本人杜撰）。

　　窗口过程函数是大多窗口都有的，它处理窗口中(包括子窗口)的每一个事件，替换窗口过程法与HOOK技术比起来孰强誰弱是很显然的，因为同一个HOOK只能拦截一个事件，处理起来相当费时，HOOK也有它的优势，但不是本文要讨论的。这里先让大家眼见为实，请看下图：-achieve satisfactory style reunification of the software interface is difficult. As netizen's MessageBox, FileDialog, FontDialog. Contents dialog, and other internal MFC DLL system even within the dialog box, in order to allow it faces no easy thing. Some say HOOK technology, the technology can really HOOK, HOOK can be said to be all-pervasive. However, the efficient use HOOK is unsatisfactory. from the most current mining technology HOOK skinnable software situation, we can prove this point. Today, we will discuss other technologies to achieve a FileDialog of independence, This technique called window replacement process (Note : I invented). Process window function is mostly window is the window handle it (including sub-window) per one incident, window replacement process of law and t
