【導(dǎo)讀】伴隨著網(wǎng)絡(luò)的出現(xiàn)，網(wǎng)頁逐漸融入人們的生活?？焖偌皶r的新聞瀏覽，五彩。它打破了地域限制，真正使信息得以共享，改變了人們的工作和。制作網(wǎng)頁是企業(yè)和個人的宣傳自己的重要手段，同時也是學(xué)習(xí)者獲取。尤其是在新聞信息領(lǐng)域，各種新聞信息的發(fā)布分秒變換，大，傳遞快速，沒有時空限制等特點恰好滿足這種要求。種新興的信息發(fā)布資源。互，保證網(wǎng)站數(shù)據(jù)的實時性。隨著Inter的進(jìn)一步發(fā)展,靜態(tài)Web站點的開發(fā)與維護(hù)變得越來越困難,互性的加強使HTML顯得越來越難以勝任。進(jìn)行有效交互,使人們感到越來越乏味,而不愿意再一次地進(jìn)入同一站點。發(fā)動態(tài)網(wǎng)頁或動態(tài)內(nèi)容成了越來越多的站點所追求目標(biāo)。所謂動態(tài)內(nèi)容是由每一。會給社會各行各業(yè)的發(fā)展注入新鮮的活力。站在網(wǎng)絡(luò)時代的前夜，我們清晰地聽。到了網(wǎng)絡(luò)時代的宣言：誰掌握了網(wǎng)絡(luò)，誰就掌握了未來。一些功能鏈接；第三部分是主體部分，放置班級信息、留言、公告模塊等。能模塊設(shè)計主要包括：前臺首頁、用戶管理、用戶管理。

　　

【正文】 能實現(xiàn)時使用 。(2)注冊 ,如果是新用戶 ,想進(jìn)入留言板就必須通過注冊 ,得到批準(zhǔn)成為合法用戶而取得留言及其權(quán)限 。(3)留言 ,已經(jīng)取得合法權(quán)限的用戶可以在留言板里進(jìn)行留言 ,或查看留言。 動態(tài)網(wǎng)頁要處理很多信息 ,這些龐大的信息一般交給后臺 數(shù)據(jù)庫去處理。而Web 數(shù)據(jù)庫應(yīng)用系統(tǒng)則通過 Inter 平臺連接數(shù)據(jù)庫 ,取得數(shù)據(jù)集 ,對其進(jìn)行添加、修改、查詢、刪除等操作。對數(shù)據(jù)庫進(jìn)行的各種操作 ,可以通過使用 SQL 語言來實現(xiàn)。本文設(shè)計的留言板是以 Access 2021 作為后臺數(shù)據(jù)庫。以操作接口而論 ,具備方便、簡易的特性 ,同時能完全利用 Windows 資源。 ASP 通過使用 ADO 所提供的對象及方法 ,能幫助用戶建立各式各樣 ,符合用戶需求的 Web 數(shù)據(jù)庫應(yīng)用系統(tǒng) —— OLEDB。 OLEDB 是連接數(shù)據(jù)庫的新低層界面。它能處理任何類型的數(shù)據(jù) ,無論它們的格式和保存方式是什么 。程序開發(fā)者并不需要確切去了解其結(jié)構(gòu) ,只需要懂得如何利用它去連接數(shù)據(jù)庫即可。 在本留言板中 ,利用 Microsoft Access2021 建立了 1 個 數(shù)據(jù)庫 ,而在其里面包含了 2 個表 :user 和 mssg。整個留言板的所有信息交流都以這 2個表為基礎(chǔ) ,所有數(shù)據(jù)的存取都通過對這 2 個表而進(jìn)行操作。表 user 是用來存放注冊用戶的資料 ,表 mssg 是用來存放所有留言的信息。在完成數(shù)據(jù)庫制作后 ,我們在對數(shù)據(jù)庫進(jìn)行存取前 ,必須要進(jìn)行數(shù)據(jù)庫的連接工作 ,進(jìn)行數(shù)據(jù)庫連接的方式有幾種 ,其中 1 種是通過“控制面板”→“管理工具 ”→“數(shù)據(jù)源 (ODBC)”來設(shè)置系統(tǒng) DSN。完成系統(tǒng) DSN 設(shè)置后 ,就可以通過 ADO 對象對數(shù)據(jù)庫進(jìn)行存取操作了。 瀏覽留言 用戶可以在該頁面瀏覽全部的留言 ,這些留言都存放在表 mssg 里 ,頁面 中的顯示留言 ,可通過對表 mssg 操作而顯示到頁面上。隨著留言的增多 ,如果在一個頁面里留言全部的留言 ,可想而知是非常不方便的 ,因此本設(shè)計為留言板提供了分頁顯示功能。通過 ASP 提供的 Recordset 的 AbsolutePage就可以輕松的對數(shù)量繁多的留言進(jìn)行有條理的分頁顯示。 發(fā)布留 言 任何的注冊用戶登錄后都擁有發(fā)布留言的權(quán)利 ,在留言主頁面提供了用來發(fā)布留言的輸入框 ,用戶可以通過表單發(fā)表留言 ,并選擇留言主題的標(biāo)志 ,發(fā)布留言是通過程序 來實現(xiàn)的。 發(fā)布留言程序先以登錄后寫進(jìn) Cookies 數(shù)據(jù)集合中的用戶名作為發(fā)布者的姓名 ,如果 Cookies 是空的話 ,就轉(zhuǎn)到提示要先登錄的頁面。確認(rèn)后接受表單提交來的信息寫進(jìn)表 mssg 中。然后轉(zhuǎn)回到 留言頁面 ,而 中的顯示留言程序根據(jù)更新后的表 mssg 而重新分頁顯示留言。 資料修改功能模塊的 設(shè)計 用戶在主頁面上點擊“修改資料”進(jìn)入資料修改頁面 ,通過這個功能模塊來修改個人的注冊信息 ,但用戶名不能修改。修改之前用戶必須要輸入正確的密碼。而修改密碼的時候 2 次輸入的密碼要相同。修改資料功能是通過程序 來實現(xiàn) ,如果資料修改成功就轉(zhuǎn)到提示修改成功的頁面并修改表 user 的數(shù)據(jù) ,如果不成功便轉(zhuǎn)到相應(yīng)提示錯誤的頁面。 相片上傳與瀏覽的設(shè)計 用戶還可以將自己喜歡的相片上傳供其他用戶瀏覽。用戶在主頁面上點擊“班級相冊”進(jìn)入頁面 。相片的上 傳：由于 ASP 使用基于開放設(shè)計環(huán)境的ActiveＸ技術(shù) ,本留言板即利用 ActiveＸ組件 ASPSmartUpload 來實現(xiàn)相片上傳功能。該組件在下載并安裝后方可使用。相片的上傳是通過文件 的上傳程序 up來實現(xiàn)的 ,并將上傳相片的所有信息都存放在表 upload里 ,包括相片的名稱、說明、上傳時間、上傳人姓名等。而且對于上傳的相片的類型和大小都有所限制 ,只能上傳 jpg 和 gif 類型的相片 ,而且相片大小不能超過 300Ｋ。如果用戶上傳的相片不符合要求 ,程序便進(jìn)行判斷 ,并顯示錯誤原因 , 相片的列表與 顯示 該功能是把所有相片的相關(guān)信息如相片的說明、上傳時間、上傳人姓名等通過列表的方式顯示出來 ,由于相片的數(shù)量可能很多 ,因此在這里也使用了分頁顯示 ,并在每張相片的說明文字上添加鏈接 ,用戶通過點擊鏈接就可以激活 中的程序 ,實現(xiàn)瀏覽相片功能。 總結(jié) 通過這次畢業(yè)設(shè)計，我從中學(xué)到了許多新的知識，而且通過這次畢業(yè)設(shè)計，培養(yǎng)了我綜合多門學(xué)科中的知識、迅速規(guī)劃并開發(fā)出目標(biāo)系統(tǒng)的能力，以及編程能力也有了很大的提高。另外也有許多心得體會，所謂系統(tǒng)開發(fā)如人生百味，酸甜苦辣皆有之。 回顧這 3個半月的系統(tǒng)開發(fā)工作 ，總結(jié)起來那就是，軟件的開發(fā)是相當(dāng)辛苦的，但成功以后的喜悅也是非常美妙的，而且我發(fā)現(xiàn)，其中你投入的心血越多，成功以后你所獲得的快樂與充實感也更多更強。 參考文獻(xiàn) 1. 肖金秀等 .Dreamweaver 網(wǎng)頁實例大制作 [Ｍ ].北京 :冶金工業(yè)出版社 ,2021. 2. 肖金秀等 .ASP網(wǎng)絡(luò)編程技術(shù) [Ｍ ].北京 :清華大學(xué)出版社 ,2021. 3. 張大斌 .

That39。s the swimming hole. Why don39。t we go over there? I39。ll tell you a story. The promise of a story was not enough to keep her out of the water. He didn39。t know if that was good or bad. He kne w she was smart, a reader, and she had an imagination. But she was also active. T hat pull was too strong for him. He sat far from the water, under some bushes, and watched her swim with the three other children still in the park this late in the evening. Maybe she would e back to him, and maybe she wouldn39。t. It wouldn39。t change his life either way, but it might change hers. She emerged dripping and infinitely cleaner from the murky water. She dressed again in her random scraps, for whatever good it did her, and came to him, shivering. I39。m cold, she said. Here. He took off his jacket. She looked at his hands as he wrapped it around her, and she reached out and touched the hardness of his shoulder. You sure must be strong, she mented. Pretty strong. I work hard, being a pusher. Just what is a pusher? she said, and stifled a yawn. Come sit on my lap, and I39。ll tell you. He did tell her, and it was a very good story that no adventurous child could resist. He had practiced that story, refined it, told it many times into a recorder until he had the rhythms and cadences just right, until he found just the right words not too difficult words, but words with some fire and juice in them. And once more he grew encouraged. She had been tired when he started, but he gradually caught her attention. It was possible no one had ever told her a story in quite that way. She was used to sitting before the screen and having a story shoved into her eyes and ears. It was something new to be able to interrupt with questions and get answers. Even reading was not like that. It was the oral tradition of storytelling, and it could still mesmerize the nth generation of the electronic age. That sounds great, she said, when she was sure he was .through. You liked it? 1 really truly did. 1 think I want to be a pusher when I grow up. That was a really neat story. Well, that39。s not actually the story I was going to tell you. That39。s just what it39。s like to be a pusher. You mean you have another story? Sure. He looked at his watch. But I39。m afraid it39。s getting late. It39。s almost dark, and everybody39。s gone home. You39。d probably better go too. She was in agony, torn between what she was supposed to do and what she wanted. It really should be no contest, if she was who he thought she was. Well . . . butbut I39。ll e back here tomorrow and you39。 He was shaking his head. My ship leaves in the morning, he said. There39。s no time. Then tell me now! I can stay out. Tell me now. Please please please? He coyly resisted, harrumphed, protested, but in the end allowed himself to be seduced. He felt very good. He had her like a fivepound trout on a twenty pound line. I t wasn39。t sporting. But, then. he wasn39。t playing a game. So at last he got to his specialty. He sometimes wished he could claim the story for his own. but the fact was he could not make up stories. He no longer tried to. Instead, he cribbed from every fairy tale and fantasy story he could find. If he had a genius, it was in adapting some of the elements to fit the world she knewwhile keeping it strange enough to enthrall herand in adlibbing the end to personalize it. It was a wonderful tale he told. It had enchanted castles sitting on mountains of glass, moist ca
