这个是 一个上传的asp 的代码 我想限制图片大小 50k以内
<%
Dim FormPath
FormPath = "TempUpload/" ''定义上传路径

Set Upload = Server.CreateObject("DvFile.Upload") ''建立上传对象
Upload.InceptFileType = "jpg,gif,png,bmp,jpeg" ''上传文件类型限制 以 “,” 号分隔
Upload.MaxSize = -1 ''限制大小 :-1为无限,单位 B
Upload.Install ''加载上传数据
If Upload.Err > 1 Then ''错误参数
''输出错误信息
Select Case Upload.Err
Case 1 : Response.Write Upload.Description ''请先选择你要上传的文件
Case 2 : Response.Write Upload.Description ''文件大小超过了限制 "&Upload.MaxSize/1024&"K
Case 3 : Response.Write Upload.Description ''非法的上传类型
Case 4 : Response.Write Upload.Description ''所上传的类型受系统限制
Case 5 : Response.Write Upload.Description ''参数有误，上传意外中止
