DirectX还没学呢

帮顶

虽然是Dx入门级别的程序，对于我这个菜鸟来说就是大项目了。。。
不懂，只好帮顶了。。。

没人在学DirectX吗？

和DirectX屁关系都没有
就是 d3dpp.SwapEffect = D3DSWAPEFFECT_COPY_VSYNC; 这一句编译错误
你看看 d3dpp.SwapEffect 是什么类型，D3DSWAPEFFECT_COPY_VSYNC 又是什么类型

我知道怎么改了，原来是我把原本他代码里的8 都改成9了 本来以为DirectX9跟DirextX8 里面的数据结构应该都一样的
但是现在知道了，不是直接换一个版本号那么简单。 以后再好好了解 改回来就成功了
d3dpp.SwapEffect = D3DSWAPEFFECT_COPY_VSYNC;这句话本身没问题，可能是DirectX9.0 里的定义不太一样吧
