asp上传文件或图片

当在一个form里需要执行resquest.conntent时不能与上传图片的功能同时放在同一个form里，最有效的解决方案是使用两个form,调用两个action,这样不容易出现二进制与content组建冲突。实现代码如下：

<form method="post" action="submit4.asp" name="form2" enctype="multipart/form-data">
<p align="left"> 　 上传图片：
<input type="file" name="file1" style="width:400" class="tx1" value="<%=image%>" size="50">
<input type="submit" name="sub1" value="提交" >
<input type="hidden" name="act" value="upload">
<br>
<font color="#990000"><br>
&nbsp; <u>允许格式：gif|jpg|png</u>(仅限etime专访)</font> </p>
</form>

此时调用的是submit4.asp这个功能扩展页，
下面是submit4这个页的可实现原码：


<!--#include FILE="upload_5xsoft.inc"-->
<%
FilePath="upfile/"
FileMaxSize="65000"
FileType=".jpg.gif.png"
fileweb="/"
%>
<% ''将当前的日期和时间转为文件名
function makefilename(fname)
fname = now()
fname = replace(fname,"-","")
fname = replace(fname," ","")
fname = replace(fname,":","")
fname = replace(fname,"PM","")
fname = replace(fname,"AM","")
fname = replace(fname,"上午","")
fname = replace(fname,"下午","")
makefilename=fname
end function
%>
<%
dim upload,file,formName,iCount
set upload=new upload_5xSoft ''建立上传对象
UpFilePath ="upfile/"
''在目录后加(/)
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<FileMaxSize then ''如果未超过文件大小限制
if instr(FileType,GetExtendName(file.fileName)) then
vfname = makefilename(now()) '文件为允许的类型执行此行
fname=vfname & "." & GetExtendName(file.FileName)
file.SaveAs Server.mappath(UpFilePath&fname) ''保存文件
'response.write fname
'response.end
'response.write file.FilePath&file.FileName&" ("&file.FileSize&") => 上传文件成功! <br>"
response.write"<script language='javascript'>{window.alert('"&file.FileName&"上传文件成功!');window.location.href='etime.asp?fname="&UpFilePath&fname&"'}</script>"
else
response.write "不支持所上传的类型！"
response.write GetExtendName(file.fileName)
response.write "<br>"
end if
else
response.write "文件大小超出限制，您最多可以上传 "& FileMaxSize &"个字节的文件数据"
exit for
set file=nothing
end if
next
set upload=nothing


function GetExtendName(FileName)
dim ExtName
ExtName = LCase(FileName)
ExtName = right(ExtName,3)
ExtName = right(ExtName,3-Instr(ExtName,"."))
GetExtendName = ExtName
end function

%>
这里值得一提的是：
<!--#include FILE="upload_5xsoft.inc"-->
这是个包含文件内容代码为：（只要将下面代码放到记事本里并将其转变为文件名为upload_5xsoft并且扩展名为.inc即可使用！）
