1 --------------------编程问答-------------------- 你要看下CUnknown在哪定义的~~ --------------------编程问答-------------------- 代码可真多。。 --------------------编程问答-------------------- 缺少库文件，看下对应方法所在的工程，然后将编译后的库文件添加到附加文件依赖里就可以了 --------------------编程问答-------------------- msimg32.dll这个文件没有复制过去吧。 --------------------编程问答-------------------- 缺少库文件，把msimg32.dll放到debug或者release文件夹下
