If SysSiteIsClose = "1" Then如果变量的值等于1 If InStr(Lcase(Request.ServerVariables("URL")),Lcase(SysSiteAdminPath))=0 Thenlcase是把字符串转为小写，instr是判断字符串a内是否包含字符串b Response.Write(SysSiteCloseNote)输出变量内容 Response.End()断点 End IfEnd IfDim Conn,ConnStr,RsConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(dbdns & SysSiteDbPath)链接数据库Call OpenConn()调用函数Set Rs = Server.CreateObject("Adodb.RecordSet")建立对象Private Sub CloseConn()声明私有过程 Conn.Close关闭连接 Set Conn = Nothing清理对象End Sub结束过程Private Sub OpenConn()声明私有过程 Set Conn = Server.CreateObject("ADODB.Connection")建立对象 Conn.Open ConnStr建立与数据库的链接End Sub结束过程%>
