调用 BinaryRead 之后，不能使用 Request.Form 集合
我用了无惧上传上传文件，但是同时也想把文件的一些相关信息（如下达时间等）即如数据库，可是系统提示“
调用 BinaryRead 之后，不能使用 Request.Form 集合。
但我想
比如说我又一个textfield，名字是keyword,应该怎么传？？
在提交时设置form1.action='xxxxx.asp?TrueName='+form1.TrueName+'&PassWord='+form1.PassWord;)
我试了这种方法也不行，望高手指教。。。。

binaryread后当然不能request.form了，你看asp帮助系统就知道了！
解决方法：
风声无组件上传封装的很好，你看看example文件夹下的内容就知道了！Top

把下面的代码保存成一个upload.inc文件.在接收上传文件的ASP页面中嵌入(include)这个文件.
