2008-02-23 09:34:26来源：互联网阅读 ()

　　建个bak文件夹啊，放数据！

　　db.asp代码如下：

<%
dim conn
dim connstr
'on error resume next
set conn=server.CreateObject("adodb.connection")
connstr="Provider=SQLOLEDB;data source=192.168.2.1;UID=sa;Pwd=123;DataBase=test"
conn.Open connstr
if err<>0 then
Response.Write "无法建立到数据库的连接！"
end if
%>

　　backup.asp代码如下：
