我的不能显示..............和书上的一样啊

天下无敌

我照书上的源码写入后怎么什么也没有啊?在编译中有几个错误也改正了,提示没有错误.就是不显示窗口什么也没有,后来我又把书里带的源码编译了就可以.但我把他的源码复制到一个新的项目里就什么都没有了,也是不显窗口,这倒底是怎么回事儿啊???

我放上代码...

不清楚……

不行啊,老兄.和原来一样啊改过也不行.是不是我的系统有问题啊.

顺便问一句，有谁知道破解PAINTSHOP PRO的方法，谢了

GameSmith

洗澡去了

老兄,有点进展啊.能看见窗口出来了,不过出来一下就没了.怎么办啊.

天下无敌

老兄,已经好了.写错了显示窗口的循环.
谢谢你给我帮忙啊.

你的错误是在使用//ZeroMemory() 不正确         这是内存清零函数
它的使用方法是Zero(这里加起始地址位置，这里加后面多少字节的内存长度）
d3dpp是用的是页面后缓冲区调配器（D3DPRESENT_PARAMETERS）类型
而d3ddm是D3D程序显示模式（D3DDISPLAYMODE）类型
它们是不同的类型，你这是张冠李戴。
你前面已经将d3ddm使用默认的显示模式。也就是当前模式。
所以，你需要将后面的页面后缓冲区调配器清零就可以拉。
不过，你清错对象拉。
