请问如何做一个专业的图片计数器？
<％
countlong=8
\’ 定义计数器位数.
On Error Resume Next
\’ 忽略所有的错误.
count=server.mappath(count.txt)
set cou = server.createobject(scripting.filesystemobject)
set out=cou.opentextfile(count,1,false,false)
counter=out.readline
out.close
\’ 打开count.txt,读出目前计数器的值.
if session(in)<>in then
\’ 判断用户是否已进入主页,防止用户刷新或再次来到此页面时计数器再加1.
session(in)=in
set out = cou.createtextfile(count,true,false)
application.lock
counter=counter＋1
\’ 计数器加1 .
out.writeline(counter)
application.unlock
out.close
\’ 建立新文件count.txt并写入加1后计数器的值.
end if
co=cstr(counter)
\’ 把数字型变量转换成字符型.
for i = 1 to countlong－len(co)
\’ 得到前面0图片的个数.
response.write
next
\’ 完成计数器前面的0图片的添加.
for i= 1 to len(co)
response.write
next
\’ 从变量co的第i位开始读.
