Older versions of MFC did something similar to message reflection by providing virtual functions for a few messages, such as messages for owner-drawn list boxes (WM_DRAWITEM, and so on).
MFC舊版本通過(guò)為一些消息提供虛函數(shù)的機(jī)制部分實(shí)現(xiàn)了類(lèi)似的功能，最典型的就是自繪制的列表框（WM_DRAWITEM等等）。

But they say this is more a reflection on the nature of the message then the writer's ability to use language correctly.
