希望vip用户登陆到myinfo.asp 普通用户登陆到index.asp
这有什么问题啊 怎么我在数据库里添加了一个用户 在登陆叶面却无法登陆到index.asp呢
[解决办法]
看了，代码没问题，不过记得在if、else、end if的时候加上response.end如：
if username= " " or password= " " then
call MsgBox( "对不起，登录失败，请检查您的登录名和密码 ", "none ", "None ")
response.end
end if
if not isnumeric(validatecode) then
call msgbox( "登录失败！验证码必须是数字，请正确填写！ ", "none ", "none ")
response.end
end if
.....后面的还有
如果问题还没得到解决，很有可能是数据库更新的问题，建议先测试数据库更新代码
rs.update
