DirectX11入门教程——第二篇：DirectX11的基础知识本系列系作者原创，可随便转发但一定要注明出处刚才明明说尽量不跳章的，为啥一进来就变成第二章，这里首先用几句话说明一下原因：因为第一章我想留给更基础更概念的GPU发展史和管线描述。在此对不起大家了。不过我保证这个系列初步成型后绝对不跳章 2010年5月微软发布了DirectX11这个DirectX SDK系列家族的最新成员，伴随着SDK的升级，DirectX11带给我的是功能的扩展，性能的阅读详情

应该是CreateWindow出现了错误，返回的总是0，所以下面无法编译下去（新人的推测），百度了几次也没解决，求前辈赐教

图形学与DirectX12学习笔记------开坑和前言几乎整个大一我都在和python和unity的gameplay部分打交道，一整年就运用了学习到的基础知识写了几个小型demo。直到大一结束的暑假前夕，我学习了unity的粒子系统，然后我发现似乎没有shader方面知识的话就只能做些基础效果，就萌生了学习shader的想法。当时是先买了一本经典《Unity Shader入门精要》，跟着书上例子敲了一遍完，又尝试了用shadergraph和ase做了一些简单特效（其实之前我是很抵触这种连连看的，但是学完才知道这玩意真好用），到这里算是入了个门吧。阅读详情

设置一下 hIcon ，在注册窗口的时候。可以直接设置为 NULL，就像 hIconSm 一样。不要留一个不确定的数值。

抱歉，前辈，我的问题没有表达清楚。我也可以生成成功，但运行时弹出弹窗，内容为“ window error”，是我设置判断window是否初始化成功的，也就是说window一直为null，这是我一直的问题。前辈你应该能看出来这个程序要做的效果，你运行的是成功的么？

您说的是为win32项目吧，而且我也设置了多字节字符集，但还是失败了

失败你也得把失败对应的错误提示复制粘贴上来才能让别人帮你看看到底哪里的问题吧。

纠正上帖：

    wc.hIconSm = NULL;
应改为
    wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);

解决了，感谢前辈！

关于自己是否适合编程的很简单的测试：在报纸或杂志上随便找一段约1000字的文章，在Word中输入一遍。输完后再参考下面答案： A里面有10处以上文字或标点错误 B里面没有文字或标点错误并敢为此跟人打赌 C里面没有文字或标点错误并且字体和排版完全与原稿一致 D打印在半透明的纸上和原稿重叠在一起检查一模一样，且自我感觉很有成就感 A不适合编程（理由：打字准确度偏低、粗心大意） B初级程序员（理由：打字准确度很高、认真细致、自信、理解全角半角概念） C高级程序员（理由：在B的基础上理解字体和排版也是电脑打印的重要因素、但相比D还不够偏执、精益求精、结果可验证） D软件项目经理（理由：能针对项目给出令人信服的细致到极点的需求说明和典型测试用例。用户几乎挑不出毛病。专业！）如果想从A变成B的话，到我的资源http://download.csdn.net/detail/zhao4zhong1/4084259里面下载“适合程序员的键盘练习”
