PollWriter.asp先检查表单变量,包括调查项目名字PollName以及(可选的)字符串LinkText和LinkURL,LinkText和LinkURL描述了用户提交其投票结果之后显示的URL。接下来脚本创建并执行从指定调查项目的S_表和A_表提取记录集的SQL命令,然后遍历这个记录集格式化单选按钮、复选框以及其它提示文本,最后输出该调查项目的HTML表单。表单中问题的名字为“CHOICE”加问题序号。当这个表单被提交的时,它的ACTION将装载PollMaker.asp(这里的函数saveResponses()从CHOICE表单元素提取投票结果,然后更新数据库,代码略)。表单中的其它隐藏变量用于将PollName、OpType、LinkText、LinkURL传递给PollMaker.asp:

PollResult.asp使用与PollWrite.asp同样的SQL命令从A_表(答案)和S_表(问题)提取记录集,接着从对应的R_表读取用户回答结果,用一个二维数组Counts统计投票结果。缺省时结果分析中不包含“没有回答”,如果要包含,则需给出表单变量ShowNoOp并指定其值为True,请参见图4中显示投票结果的URL。
