if rs.RecordCount =0 then

Response.Write "此會員號不存在！"

else

if trim(rs.Fields("PWD"))<>trim(Request.Form("txtPWD")) then

Response.Write "密碼不正確！"

Response.Write rs.Fields("ID") & "<br>"

Response.Write rs.Fields("PWD") & "<br>"

Response.Write Request.Form("txtPWD")

else

這個登錄界面和大多數網上的登錄新用戶類似。

小結：
　

幾個程序都做了一個簡要地說明，當然，程序做地非常簡單，還有很多功能沒有
或有待完美，但它卻示范了一個簡單的范例，在此僅供大家參考。如果大家有興趣，
可以把上面的程序試一下，祝大家成功！
