原创的ASP文件上传函数库，比动网、amao的都差了很多，不过是学习的好资料
原创的ASP文件上传函数库，比动网、amao的都差了很多，不过是学习的好资料
54powerman
说明：
如果你需要file表单的串值，用GetFullName("file")
如果需要file表单的文件名，用GetFileName("file")
如果需要file表单的扩展名，用GetExtName("file")
如果需要普通文本表单的值，用MyRequest("password")
如果需要file表单的二进制值，也是用MyRequest("file")
保存文件用SaveFile("file","myUpload.jpg")
写入数据库的格式：
Rs.AppandChunk MyRequest("file")
