如何在UNICODE工程下使用一个MBCS成功编译的MD5加密类

[rlexyum]

在网上找了一个可用的MD5加密了，其使用MBCS的工程编译无问题并能成功运行
但是把工程调试为UNICODE以后就不能编译成功了，我试着修改，但是出现的问题是我能力范围之外的；
1.请问如何修改（我附上源代码），在UNICODE下能成功编译并且结果正确；
2.如果不能修改成UNICODE工程，那么我UNICODE工程如何调用MBCS的MD5加密类呢？

楼主可以把你的工程打包上传到 CSDN ，让别人下载帮你调试啊，你贴这么长的代码，人家怎么看啊

自己顶下 求解啊

[qq614190370]

内部用多字节也没问题

外部打个包用 CW2A 传参数

要不你就 用TChar 把所有""换成 _T("")

[Eleven]

或者你传入数据的时候，先转一次，将wchar_t*转成char*;
WideCharToMultiByte(CP_ACP, ...);

实在不好修改，就自己调用类的函数时，先自己把参数从unicode转换为ANSI，然后调用

[CppCoder]

在使用MD5加密类前，把输入数据转换成MBCS
在用完MD5加密类后，把输出数据转换成UNICODE
可以用下列方法转换
WideCharToMultiByte
MultiByteToWideChar

能告诉我具体如何操作么？

[jwybobo2007]

拟直接贴错误信息比较好

[用户 昵称]

没什么不一样的，少用CString就好了，比如将CString *改为char *。

[llshsky]

CString str=_T("111111111");
USES_CONVERSION;
A2T(md5.MDString(T2A(str)));
试试这个
