|800A0001 Unspecified error
When uploading files with AspUpload 3.0 (and higher),
the following error may be thrown by the Save method:
In most cases it means that your upload script
uses Request.Form or Request.QueryString prior to calling Upload.Save .
As a result, the BinaryRead method of the Request object fails.
You must never use Request.Form in your upload script because
the ENCTYPE="multipart/form-data" attribute of your form makes this
collection unusable. Use Upload.Form instead.
Remeber, however, that the Upload.Form collection is
populated by a call to Upload.Save, therefore you can only use
Upload.Form after a successful call to Upload.Save.
简单来说,就是说你使用了这个组件 就不要再使用 Request.Form or Request.QueryString 来获取参数，都要用Upload.Form来获取，不然就报错这个错
