这里提供一个控制台 应用程序去播放一个音、视频文件。这个程序只有几行长。
在前面介绍了一个基 于 DirectShow 的应用程序，必须要进行如下几个基本步骤：
1. 建立一个 Filter Graph Manager 的实例 .
2. 使用 Filter Graph Manager 建立一个 filter graph.
3. 运行这个 graph 。
 
调用 CoInitialize 去初始化一个这个 COM 库。https://blog.youkuaiyun.com/liangls1982/article/details/6340834https://blog.youkuaiyun.com/liangls1982/article/details/6340834liangls1982Fri, 22 Apr 2011 11:00:00 +0800将字符串转换为整型的函数：

以前经常遇到这个警告信息，因为运行并没有什么问题，所以也没深究。但是耿耿于怀那个“ 0 个错误，0 个警告”的成功提示，在网上搜了一下。原来问题出在默认库的引用选择上。
VS2008，项目——属性——配置属性——C/C++——代码生成：他有/MT，/MTd，/Md，/MDd四个选项，你必须让所有使用的库都使用相同的配置，否则就会有相应的提示，甚至可能会出现无法解析的函数。有时我们使用的库不是自己可以控制的，那么就只能把工程属性设置成河你使用的库相同的选项。

c#语言中可以在switch中，以字符串作为case的条件。

我觉得宏定义不行，用map尝试一下，下面是给你一个例子。

map errorMap;

errorMap.insert(map::value_type("ERR01",1));
