VC++出现error LNK2005该如何解决啊

本人在用VC++6.0编译陆其明老师的《Windows media 编程导向》中加水印组件（DmoVideoWatermark）时出现如下错误：
Linking...

Error executing link.exe.

DmoVidWmrk.dll - 5 error(s), 2 warning(s)

请问这是什么错误啊，该如何解决？我在网上查了一下，似乎没有相关的解决方案....

Answer 1

2005是重复定义，一般是头文件重复包含的问题
2001是缺少定义，一般是函数没有实现

Answer 2

你这是什么？
我看不懂，拿分走人。
