多百度一下，会找到很多参考代码，然后稍改就能搞定。
例：以服务端ASP代码为例
网页部分：[code=xml]<FORM id= "FileEditForm " Name= "FileEditForm " Action= "UpdateFile.asp " enctype= "multipart/form-data " method= "post ">
<INPUT id= "FileTitle " Name= "FileTitle " type= "text " size=50 style= "background-color: #ffffff; font-family: 宋体; font-size: 12px; border-style: groove; border-width: 1 ">
<INPUT type= "file " id= "IconPic " Name= "IconPic " value= " " size= "39 " style= "background-color: #ffffff; font-family: 宋体; font-size: 12px; border-style: groove; border-width: 1 ">
<INPUT type= "submit " value= "确 定 ">
</FORM> [/code]ASP部份
文件名：UpdateFile.asp
插不进VB脚本代码，用JAVA脚本代码器编辑,VB脚本部份可能有问题，你注意点看哈[code=jscript]<SCRIPT RUNAT=SERVER LANGUAGE= "JavaScript ">
function getfileextraname(string_value)
{
string_value=trim_spaces(string_value);
var index=string_value.length-1;
while(index> =0&&string_value.charAt(index)!= ". ")
{
index--;
}
if(index!=-1)
{
return string_value.substring(index+1,string_value.length)
}
else
{
return " ";
}
}
function trim_spaces(string_value)
{
var start;
var end;
start=0;
end=string_value.length-1;
while(string_value.charAt(start)== " ")
{
start++;
}
while(string_value.charAt(end)== " ")
{
end--;
}
return string_value.substring(start,end+1);
}
function get_newfilename()
{
var Date_obj=new Date();
return "Adj "+Date_obj.getTime();
}
