如果读取outlook的信件(300分)

Outlook Express的邮件存储格式没有什么好说标准的文本信息，只不过邮件的正文和附件
使用Base64编码压，现在解码的代码实在是太多了，找一个解开即可读出其内容。
to woodstock:
CreateOleObject('Outlook.Application');这样的语句建立的是OUtlook的对象（不是OE)
当然就不行了，以前我也研究过这个问题，但是最终的结论是OE好像无法支持OLE自动控制。

如果是OE早期的版本，可以直接读取其源文件，然后自己解码，但是OE5以后，对其原码经过了
一些特殊的处理，这就难多了。

to woodstock:
你还在做那个东西吗?我准备从新写CoolMail,现在已经动手了,不过我这段时间比较少
没有多大改动 估计在等一段时间就可以好了.
如果你要对付的是OE应该没有多大问题,我看了一下,好像没有什么改动.如果你要对付
Outlook就难了,好像有自己的格式,大概是RTF的

这个方法没有用的，因为这样能够得取OutLook的邮件，但是不能得到OutLook Express的。

是要显示OE邮件的内容吗?OE邮件内容好像分两部分,前一部分是普通文本,后一部分是超文本,
我没仔细研究过它的格式,每次显示都显示了两遍

多人接受答案了。
