ASP初学者常用的代码

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") c & 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 'c & 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() c 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.动网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)
