寻无组件上传源程(无错版),悬赏50点

[wanzhong]

我在www.chinaasp.com下载的无组件上传源程总有错
我急用,请帮忙,谢谢!

大哥，我也急用，但无组件的上传还没有见过。

[zjdisy]

where? I neet it too, send the source code to me ok?

[solomon]

看看iis4中的sample
/inetpub/scripts/*.*

[蝈蝈俊]

试一试以下的:
下面将介绍一系列可以不用组件，而使用纯粹的ASP代码来上传文件
呵呵，我想这将给很多拥有个人主页的网友带来极大的方便。
这个纯ASP代码由三个包含文件组成，代码中只使用了FileSystemObject
和Direction两个ASP固有对象。而不需要任何附加的组件，注意，为了保证
这段代码的出处，我没有对代码中的任何地方进行过修改。
希望能够对大家有所帮助：
