将连接数据库的代码隐藏在DLL中(1) 其实，大家在书写ASP程序时，最担心的可能就是数据库的连接信息，会被一些人看到，进行一些破坏。下面我们用VB6.0来做一个动态链接库(.dll)来隐藏数据库的连接信息。
启动vb6.0，新建-->Active dll工程。单击"工程"-->引用,选择"microsoft active server pages object library"
和"microsoft activeX data objects 2.1 library"两项。将类模块的名称改为dCSS技巧">CSS.将工程的名称改为yygwy.保存工程文件yygwy.vbp和类文件dcss.cls。
在dcss.cls中写入:
Private myscriptingcontext As ScriptingContext
Private myapplication As Application
Private myrequest As Request
Private myresponse As Response
Private myserver As Server
Private mysession As Session
Public Sub onstartpage(passedscriptingcontext As ScriptingContext)
Set myscriptingcontext = passedscriptingcontext
Set myapplication = myscriptingcontext.Application
Set myrequest = myscriptingcontext.Request
Set myresponse = myscriptingcontext.Response
Set myserver = myscriptingcontext.Server
Set mysession = myscriptingcontext.Session
End Sub
Public Sub onendpage()
Set myscriptingcontext = Nothing
Set myapplication = Nothing
Set myrequest = Nothing
Set myresponse = Nothing
Set myserver = Nothing
Set mysession = Nothing
End Sub
'以上语句是必须的。
'定义两个公有函数
Public Function rsresult(strsql As String) As Recordset
