asp无组件上传图片并生成缩略图

先创建一文件夹，并创建虚拟目录或站长点。

1.增加上传页xAdd.html

<html>

<head>

<title>无组件上传</title>

</head>

<body>

</form>

</body>

</html>

2.上传页upload.htm

<html>

<head>

function check_file()

{

var strFileName=form.FileName.value;

if (strFileName=="")

{

alert("请选择要上传的文件");

return false;

}

</SCRIPT>

</head>

</form>

</body>

</html>

3.上传保存代码页upfile.asp

Const MaxFileSize=300 '上传文件大小限制单位k

Const UpFileType="gif|jpg|bmp|png" '允许的上传文件类型

set fs=createobject("scripting.filesystemobject")

<html>

<head>

</head>

<body>

call upload_0() '使用化境无组件上传类

</body>

</html>

sub upload_0() '使用化境无组件上传类

set upload=new upload_file '建立上传对象

for each formName in upload.file '列出所有上传了的文件

set file=upload.file(formName) '生成一个文件对象

if file.filesize<100 then

msg="请先选择你要上传的文件！"

founderr=true

end if

if file.filesize>(MaxFileSize*1024) then

msg="文件大小超过了限制，最大只能上传" & CStr(MaxFileSize) & "K的文件！"

founderr=true

end if

fileExt=lcase(file.FileExt)

Forumupload=split(UpFileType,"|")

for i=0 to ubound(Forumupload)

if fileEXT=trim(Forumupload(i)) then

exit for

end if

randomize

end if

End If

Jpeg.Save Server.MapPath(chsave)

Jpeg.close

Set Jpeg = nothing

msg="保存缩位图成功! --"

else

msg="保存缩位图不成功!--"

end if

msg=msg"上传文件成功！"

FileType=right(fileExt,3)

strJS=strJS & "window.parent.document.getElementById('PicPath').value='" & replace(filename,"../","") & "';" & vbcrlf

'******************* 无组件上传类 ********************************

'声明:此上传类是在化境编程界发布的无组件上传类的基础上修改的.

'在与化境编程界无组件上传类相比,速度快了将近50倍,当上传4M大小的文件时

'服务器只需要10秒就可以处理完,是目前最快的无组件上传程序,当前版本为0.96

'源代码公开,免费使用,对于商业用途,请与作者联系

'文件属性：例如上传文件为c:/myfile/doc.txt

'FileName 文件名字符串 "doc.txt"

'FileSize 文件大小数值 1210

'FileType 文件类型字符串 "text/plain"

'FileExt 文件扩展名字符串 "txt"

'FilePath 文件原路径字符串 "c:/myfile"

'使用时注意事项:

'由于Scripting.Dictionary区分大小写,所以在网页及ASP页的项目名都要相同的大小

'写,如果人习惯用大写或小写,为了防止出错的话,可以把

'sFormName = Mid (sinfo,iFindStart,iFindEnd-iFindStart)

'改为

'(小写者)sFormName = LCase(Mid (sinfo,iFindStart,iFindEnd-iFindStart))

'(大写者)sFormName = UCase(Mid (sinfo,iFindStart,iFindEnd-iFindStart))
