1.获得系统时间:
<%=now()%>
2.取得来访用的IP:
<%=request.servervariables("remote_host")%>
3.获得系统,浏览器版本:

4.去除IE混动条:


5.进入网站,跳出广告:

6.随机数:
<%randomize%>
<%=(int(rnd()*n)+1)%>
N为可改变数
7.向上混动代码:
hhhhhhhhhhhhhhhhhhh
8.自动关闭网页:

本页10秒后自动关闭,请注意刷新页面


9.随机背景音乐:
<%randomize%>

可以修改数字,限制调用个数,我这里是60个.
10.自动刷新本页面:

11.ACCESS数据库连接:
<%
option explicit
dim startime,endtime,conn,connstr,db
startime=timer()
‘更改数据库名字
db="data/dvBBS5.mdb"
Set conn = Server.CreateObject("ADODB.Connection")
connstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(db)
‘如果你的服务器采用较老版本Access驱动,请用下面连接方法
‘connstr="driver={Microsoft Access Driver (*.mdb)};dbq=" & Server.MapPath(db)
conn.Open connstr
function CloseDatabase
Conn.close
Set conn = Nothing
End function
%>
12.SQL数据库连接:
<%
option explicit
dim startime,endtime,conn,connstr,db
startime=timer()
connstr="driver={SQL Server};server=HUDENQ-N11T33NB;uid=sa;pwd=xsfeihu;database=dvbbs"
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open connstr
function CloseDatabase
Conn.close
Set conn = Nothing
End function
%>
13.用键盘打开网页代码:

这里是Ctrl+Enter和Alt+S的代码 自己查下键盘的ASCII码再换就行
14.让层不被控件复盖代码:
# 前面
# 后面


15.FLASH广告代码:

16.VBS弹出窗口小代码:

16.使用FSO修改文件特定内容的函数
function FSOchange(filename,Target,String)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject("scripting.FileSystemObject")
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(filename),1,True)
FiletempData = objCountFile.ReadAll
objCountFile.Close
FiletempData=Replace(FiletempData,Target,String)
Set objCountFile=objFSO.CreateTextFile(Server.MapPath(filename),True)
objCountFile.Write FiletempData
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End function
17.使用FSO读取文件内容的函数
function FSOFileRead(filename)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject("scripting.FileSystemObject")
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(filename),1,True)
FSOFileRead = objCountFile.ReadAll
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End function
18.使用FSO读取文件某一行的函数
function FSOlinedit(filename,lineNum)
if linenum < 1 then exit function
dim fso,f,temparray,tempcnt
set fso = server.CreateObject("scripting.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),1)
if not f.AtEndofStream then
tempcnt = f.readall
f.close
set f = nothing
temparray = split(tempcnt,chr(13)&chr(10))
if lineNum>ubound(temparray)+1 then
exit function
else
FSOlinedit = temparray(lineNum-1)
end if
end if
end function
19.使用FSO写文件某一行的函数
function FSOlinewrite(filename,lineNum,Linecontent)
if linenum < 1 then exit function
dim fso,f,temparray,tempCnt
set fso = server.CreateObject("scripting.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),1)
if not f.AtEndofStream then
tempcnt = f.readall
f.close
temparray = split(tempcnt,chr(13)&chr(10))
if lineNum>ubound(temparray)+1 then
exit function
else
temparray(lineNum-1) = lineContent
end if
tempcnt = join(temparray,chr(13)&chr(10))
set f = fso.createtextfile(server.mappath(filename),true)
f.write tempcnt
end if
f.close
set f = nothing
end function
20.使用FSO添加文件新行的函数
function FSOappline(filename,Linecontent)
dim fso,f
set fso = server.CreateObject("scripting.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),8,1)
f.write chr(13)&chr(10)&Linecontent
f.close
set f = nothing
end function
21.读文件最后一行的函数
function FSOlastline(filename)
dim fso,f,temparray,tempcnt
set fso = server.CreateObject("scripting.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),1)
if not f.AtEndofStream then
tempcnt = f.readall
f.close
set f = nothing
temparray = split(tempcnt,chr(13)&chr(10))
FSOlastline = temparray(ubound(temparray))
end if
end function
利用FSO取得BMP,JPG,PNG,GIF文件信息(大小,宽、高等)
