线程文件[MFC]线程优先级设置,下拉列表框ComboBox,复选框CButton,列表框CListBox的使用

发一下牢骚和主题无关：

青春，有嬉笑声与哭泣声夹杂的年华，青春的少年是蓝天中翱翔的幼鹰，虽然没有完全长大，有些稚气，有些懵懂，脱不开父母的双手却极力想去找寻属于自己的一片天空，为的是一时的激情，为的是一种独自翱翔的感觉！

文章结束给大家分享下程序员的一些笑话语录： 自行车
一个程序员骑着一个很漂亮的自行车到了公司，另一个程序员看到了他，问 到，“你是从哪搞到的这么漂亮的车的？”
骑车的那个程序员说， “我刚从那边过来， 有一个漂亮的姑娘骑着这个车过来， 并停在我跟前，把衣服全脱了，然后对我说，‘你想要什么都可以’”。
另一个程序员马上说到， “你绝对做了一个正确的选择， 因为那姑娘的衣服你 并不一定穿得了”。
