asp上传视频

简单的应用到化境官方站点下载压缩文件，其中里面有例题
不过我这里是重新编辑的无组件上传，增添了如下内容：

1，支持图片、音频、视频、压缩等各类型文件的上传（可自定义限制的格式文件）

2，对不同类型文件的文件夹归类（按照文件类型建立文件夹，并按“年-月”建立子文件夹）

3，上传的文件名不再采用流水号（这样对搜索不好），当然也加了随机数

4，还有功能程式的说明，具体看文件内容

声明：既然是上传，一般是需要相关上传组件的支持的，而无组件上传则是由网络上盛传的稻香老农的无组件上传类，目前版本为V2.0，该文件内容如下，拷贝代码，保存为upload.inc

接着，需要一个正常的后台信息录入平台，该平台页面是通过信息内容的输入，并提供“浏览”表单元素以提供本地文件的上传，该文件内容如下，拷贝代码，保存为index.asp

其中，index.asp中的“浏览”表单元素的出现是在浮动框架内的upload.asp，用浮动框架是防止文件上传的同时与index.asp的信息干扰，该文件内容如下，拷贝代码，保存为upload.asp

最后，最重要的文件就是如何将upload.asp选择的本地的文件传递到服务器上定义的文件夹中，action="upfile.asp"，该文件内容如下，拷贝代码，保存为upfile.asp

<%@LANGUAGE="VBscript" CODEPAGE="936"%>
