有懂VB的VC高手没？或者懂VC的VB高手也行。

懂的话帮忙转换成VB代码(内容为SEED加解密函数）：

不能沉啊，再顶一下，睡觉去，希望醒来有人帮我。

[Heister]

应该是 md5算法吧,晚上 有asp写的,直接拷贝到vb里就行了

[handsomge]

俺懂VB，俺也用VC，路过，帮顶

[hylyz]

不是MD5，是韩国的SEED算法，没人帮我吗？

[wylcy]

VB没有移位算法，转换是可以,就是太麻烦了，不如就把上面的代码编译成dll，在VB里调用好了

[熊孩子开学喽]

楼主要干嘛？吓唬人可不用这样吧

[hylyz]

我可不是吓人啊。

在VB里要用到SEED算法，人家好心人帮我写了个函数，可他只会VC，我呢只会VB，没辙了，想有人帮帮我，把上面的VC函数转换成VB就行了。其实不是太难吧，只要能看懂VC，我相信这是件容易的事。

[hylyz]

实在没人愿意转换的话，也请会VC的人把上面几个主要地方说明一下也好。

我自己来写好了。

[daisy8675]

[Featured]

看见莫依来，也顶一下

[hylyz]

顶到出来为止。

[dxj1234]

这么麻烦谁愿意自找

[hylyz]

唉，看来CSDN里的大部分人比较自私。

上面的知道这函数哪来的吗？
在一论坛上我找SEED算法，人家给我网址。
我说看不懂，最好有代码。他给写的，不过他只会VC。

[supergreenbean]

看了头昏……建议楼主还是直接编译成DLL文件供VB调用，这样省时省事，效率又高

[是是非非]

就是，编译成DLL不就搞定了吗？

[LuBingLin]

晕,又一个要代码的,累了不想翻了

[hylyz]

我编译老是出错，谁帮我搞一下啊.愿帮忙的加我QQ：944186

[Gutta]

supergreenbean(超级绿豆 - 要准备发芽了)
说得对，写成DLL，来调用，比较快速，又不用关心代码转化的问题，只要参数类型和函数功能了解了就可以了。

http://www.xf3924.com/bbk/showbbs.asp?bd=8&id=38&totable=1
里有怎么用VC写DLL，然后VB调用的内容，可以参考一下。

[qyii]

如果只有头文件,没有源文件,编译当然出错了!呵呵~~

[hylyz]

楼上的帮帮我，帮我编译一下。我QQ：944186,我把源程序传给你。
