set rs=nothing%>

这是chklogin.asp文件的代码, 问题是:可以从定向到test易做图.asp,但是不能判断前面的准考证号和姓名,如果把"response.redirect "test易做图.asp?"&Request.QueryString"这句注释掉,则可以判断以上条件.
现在想如何能实现判断以上条件,并能把参数传递过去. --------------------编程问答-------------------- response.redirect "test易做图.asp?"&Request.QueryString跟判断前面的准考证号和姓名有什么关系？想不通 --------------------编程问答-------------------- 没弄过asp 帮顶 --------------------编程问答-------------------- response.write "test易做图.asp?"&Request.QueryString
可以得到下面的
test易做图.asp?StudentID=600743&Name=%E3%C6%D0%A3%C9%FA&Subject=%D0%C5%B4%FB%BF%BC%CA%D4&send=%B5%C7%C2%BC

而且代码上面的检查条件也可以顺利进行
