ASP常用源代码的总结（下）

asp是active server page的缩写，意为“动态服务器页面”。asp是微软公司开发的代替cgi脚本程序的一种应用，它可以与数据库和其它程序进行交互，是一种简单、方便的编程工具。

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：　

<script language="javascript">  
function ctlent(eventobject)  
{  
if((event.ctrlkey && window.event.keycode==13)||(event.altkey && window.event.keycode==83))  
{  
window.open('网址','','')  
}  
}  
</script> 

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：

<div z-index:2><object xxx></object></div> ＃ 前面  
<div z-index:1><object xxx></object></div> ＃ 后面  
<div id="layer2" style="position:absolute; top:40;width:400px; height:95px;z-index:2">
<table height=100% width=100% bgcolor="#ff0000"><tr>
<td height=100% width=100%></td></tr></table><iframe width=0 height=0></iframe></div>  
<div id="layer1" style="position:absolute; top:50;width:200px; height:115px;z-index:1">
<iframe height=100% width=100%></iframe></div> 

15.动网flash广告代码：

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"  
codebase=http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0
 width="468" height="60"> 
<param name=movie value="images/yj16d.swf"> 
<param name=quality value=high> 
<embed src="images/dvbanner.swf" quality=high 
pluginspage=http://www.macromedia.com/shockwave/download/index.cgi?p1_prod_version=shockwaveflash;
;;;;;;;;;;; type="application/x-shockwave-flash" width="468" height="60"></embed></object> 

16.vbs弹出窗口小代码:

<script language=vbscript>  
msgbox"你还没有注册或登陆论坛","0","精品论坛"  
location.href = "login.asp"  
</script>

17.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

18.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 

19.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 

20.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 

21.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 

22.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 

到此，关于asp常用代码的总结篇，就为大家介绍完了，希望对大家有帮助。
