<%

uppath=request("uppath")&"/"
'文件上传路径
filelx=request("filelx") '文件上传类型
formName=request("formName") '回传到上页面编辑框所在Form的Name
EditName=request("EditName") '回传到上页面编辑框的Name

我也不是很专业,一起学习吧。但">
应该没问题,除非你存的图片路径中有双引号会导致错误。
<%
sql="SELECT * FROM Table_Name"
set rs=server.CreateObject("Adodb.Recordset")
rs.open sql,Conn,1,1
%>
">
<%
rs.close
set rs=nothing
%>

回答3:

代码贴完整些,你确定是这句,使整个页面出现问题?

顺便问下,你access表中的字段都是用中文名字吗?习惯不好!

回答4:

你先用response.write rs("存图片的路径的字段名") 查看一下结果能够输出不,可以的话就不是这个地方的问题,不过从你的错误的地方应该是的在某一个地方少写一个东西,具体的你要把详细代码贴出来!你可以参考楼上的具体例子!
