再接__我的不能显示..............和书上的一样啊_

天下无敌

我高兴的太早了,画出来的窗口是我的建立window时用的白画刷,白色的,可在初始化的时候应该是蓝色的.要说是我的显卡不支持那为什么书上的代码可以编译啊,我的代码是全复制过去的啊.我的显卡是GF2,最新的驱动,98和2000sp2双系统.要看代码在下面:

还有记得原来用OPGL要显示一个黑色的窗口,可是只是屏幕四周是黑的.中间却是桌面上的东西.唉,不明白啊??????

源代码之光

可能书上的代码有误
如果书上的代码你能顺利执行，那么，把你自己写的代码，一条一条的复制回书上的代码，看来你只能用这种方法了

天下无敌

唉!!!

天下无敌

在win98下代码可以通过，为什么在2000下不能通过呢？？？？

GameSmith

我运行了你的代码，是蓝色的窗口啊？你有什么问题？

GameSmith

我还在W2K下编译的，你用的是不是VC++6.0

天下无敌

是啊,不过我一装上vc6以后,电脑就常出毛病,总说什么什么地方为只读,打不开什么什么文件,需要关闭或调试.

GameSmith

那重装

天下无敌

重装没用的每次都一样,不过有网友说是内存泄露,说2000比98对内乱存的要求严格.老兄有什么看法?

GameSmith

呵呵，那俺就不知道了，你去问问W2K开发小组吧
你的VC会不会有问题或系统，重买一个或打个补丁
