play.cpp

应朋友邀请,写的一个纯C++的五子棋游戏,用到了windows的sdk

#include "Gomoku.h"
/*=========================================================
程序小结：
	本程序完全以C++和windows api来实现，比较底层，所以包括窗口，菜单等都要自已来设计。

窗口及事件：
	windows中以WinMain()来作为程序的入口函数，并根据参数自动绘制窗口。以回调函数来实
现事件机制，本程序以GomokuProc作为回调函数，并处理各种事件。

菜单：
	实现比较简单，也比较简陋，当WM_LBUTTONDOWN事件发生时，程序判断鼠标是否位于某个菜
单区域之内，来决定是否响应该消息。
