我不太懂你的意思
是不是没有加载LIB文件啊

[DaQiangZi]

是呀，明明报的是CRijndaelObj::MakeKey找不到，而不是CRijndaelObj::XRijndael::MakeKey找不到，一定是你的类说明错了，检查一下.h文件吧。

应该不是没有LIB，

看样子，是用MFC的嵌套类方式来实现的，可能是嵌套类没有用好，同意FFXI(黑)的猜测

[index]

刚才是没加载lib，加载后还有三个link错误

不好意思，还忘记了定义函数，谢谢各位

[DaQiangZi]

错误报的是CRijndaelObj::MakeKey找不到，而不是CRijndaelObj::XRijndael::MakeKey找不到，所以一定是你的.h文件写错了。

[chenybin]

：）

[FFXI]

CRijndaelObj::MakeKey

是否把
MakeKey
EncryptBlock
DecryptBlock
定义成CRijndaelObj的成员了.他们应该是CRijndaelObj::XRijndael的成员。
贴一下类的声明吧!
