【正文】 密碼框 —— 用來驗證新密碼。 提交和重填 按鈕。 在數據庫中修改管理員密碼 在數據庫中修改管理員密碼的步驟如下： (1)使用 Request 對象的 Form 集合得到用戶輸入的信息，這些信息包括用戶名、原密碼、新密碼和確認新密碼。代碼如下： % dim user_id,old_password,new_password1,new_password2 user_id=request(user_id) old_password=request(old_password) new_password1=request(new_password1) % (2)判斷新密碼和確認新密碼是否相符，如果不相符，提示用戶輸入錯誤并重新生成表格。代碼如下： % if new_password1new_password2 then p兩次密碼輸入有誤！ /p pa href=重新輸入！ /a/p else end if % (3)連接數據庫并檢查用戶名和原密碼是否正確， 代碼與前面連接數據庫的代碼相同。 (4)使用 SQL 語句修改密碼，代碼如下： % =UPDATEclassuserSET user_password=39。amp。new_password1amp。39。 WHERE user_id like 39。amp。user_idamp。39。 % 結論 本文詳細闡述了 在線投票系統(tǒng)的 設計（包括功能模塊設計、 數據庫結構設計等），并實現了投票 系統(tǒng)的 主要生成百分比 功能及其它功能。 采用了大型數據庫，適合大批量數據的處理 ，使教師從煩瑣的手工操作中解放出來，把大量的重復性工作交給計算機去做，提高了工作效率。 目前，該 在線投票 系統(tǒng) 還有不少問題需要進一步解決。譬如， 在投票選項可以劃分得更詳細一些，另外 可以 授予不同用戶以不同的系統(tǒng) 使用權限（這可以通過在每一功能模塊進入 前增加身份判斷來完成），可以滿足更多的 條件。 該系統(tǒng)在界面設計上比較粗糙，整體頁面布局不夠美觀。 對于計算機專業(yè)的我來說 并沒有多少系統(tǒng)設計的經驗，所以在編碼過程中發(fā)現自己原來的很多想法并不能很好地實現。希望在以后的工作中不斷學習，完善該系統(tǒng)的功能，使它更加人性化。 致謝 本文是在我的導 師 老師 的悉心指導下完成的，在系統(tǒng)的研制過程中，從系統(tǒng)分析設計到具體實現，導師都給予了具體、細致的指導。 劉亮老師 平易近人的作風、對知識的敏銳思維、嚴謹治學的風范和孜孜不倦的科研精神永遠都是我學習的榜樣。 向所有關心和幫助過我的老師、 同學和朋友表示最誠摯的謝意！ 參考文獻 [1]求是科技 .ASP 數據庫開發(fā)技術與工程實踐 .北京 :人民郵電出版社， [2] 運行環(huán)境搭建 .ASP 酷網動力 論壇 － ASP 專欄， [3]（美）奈伯格（ Naiburg,.），（美）美克斯瓊克（ Maksimchuk,.）著 ； 陳立（美） Eric ,Robert UML關于對象和組件軟件工程 .北京 :人民郵電出版社， [4]玄偉劍 .中文版 Dreamweaver MX 設計與提高 .上海 :上?？茖W普及出版社， [5]熊衛(wèi)衛(wèi) .網絡投票系統(tǒng)設計與實現 .吉林大學學報 , [6]楊文杰、王克蒙、劉浩學 .管理信息系統(tǒng)的開發(fā) .北京印刷學院學報， [7] ASP實現 打印功能 .ASP酷網動力 論壇 － ASP 專欄， [8]宋振會 .

Multicasting minimizes the work bandwidth used. If clients do not use the station to receive the ASF stream, then each client requires its own connection to a server. This quickly consumes work bandwidth and limits the ability of the work to deliver information. Distribution mode is a station characteristic that defines whether a station is to be used for multicasting, distribution, or both. ? Multicast stations deliver ASF streams to many clients but use only the bandwidth of a single stream. ? Distribution stations deliver ASF streams to other Windows Media servers via unicast. A station that is solely a distribution station does not have an IP address or port, so clients cannot view the stream that the station delivers. ? Stations enabled for multicast and distribution deliver ASF streams to other Windows Media servers via unicast. Clients can also view the ASF content on this station via multicast. A station contains all the information needed to deliver an ASF stream to Windows Media Player, including IP address, port, stream format, timetolive (TTL) value, and so on. This information is stored in an .nsc file. Windows Media Player must be able to access the .nsc file so that it can locate the IP address that the station is using to stream ASF content. The .nsc file is typically made available to Windows Media Player from a shared work directory or from a Web server directory. Windows Media Player extracts the URL to the .nsc file when it opens an announcement that is delivered to it in an message, via UNC path, or from a Web page link. The Multicast Stations page in Windows Media Administrator is the access point for creating and managing stations. This page also provides an interface for anizing streams into the programs delivered on the stations you create. Understanding distribution stations A distribution station is a helper station. It delivers an ASF stream from Windows Media server A to a station on Windows Media server B so that Windows Media server B can multicast that ASF content. A distribution station provides a way to: ? Distribute a stream between work segments that are not connected by multicastenabled routers. ? Distribute a stream past a firewall. Other stations access the distribution station by creating a connection to the distribution station .nsc file using the MSBD protocol. For example, if you want Station2 on ServerB to multicast the ASF content from distribution station, Station1 on ServerA, you use Station1 as the stream source. That is, the stream source for Station2 is Note When you distribute streams between servers, you must not exceed the distribution limit, the number of MSBD connections that a distribution station can acmodate. By default, a distribution station can support only five MSBD connections to other stations. As you configure stations on remote Windows Media servers to use a distributed ASF stream, you must adjust the distribution station Distribution Limit to acmodate the additional remote connections, or use more than one distribution station as the source for the remote station. For more information about adjusting the Distribution Limit, see Editing station properties. Delivering streams over a nonmulticastenabled work If your work does not use multicast routers, you can multicast a stream only within the work segment that contains Windows Media server ponents. Clients on other segments of the work cannot receive the ASF stream multicast because it does not originate within their segment. Clients throughout the work can still receive the stream if the ASF content is multicast within the local segment, and distributed to Windows Media servers on the other work segments. The station on the local work segment must have both multicast and distribution cap
