题记:写这篇博客要主是加深自己对对话框control的认识和总结实现算法时的一些验经和训教,如果有错误请指出,万分感谢。
照着写的一个Demo,,地址如下,
立一个基于对话框的工程(名称:OpenGL)
并且在设置的Link里加入库opengl32.lib glu32.lib glaux.lib
为对话框添加picture control 控件,ID:IDC_RENDER
每日一道理 在每个人心中,都曾停留过那些值得怀念的人,也许还在,也许早已消逝,在茫茫人海中丢失,于是,那份怀念便得凄凉,因为模糊的记忆中只剩下一个“空壳”,没有什么,甚至连自己的心都装不下,时间把一切抹平,也把当日的泪水封锁,因为已经没有,怀念只是悲凉!
