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。接上篇>>

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">
<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">
<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
