What I say? I speak true when I say dat Buck two devils. This was Francois39。 and he answered curse w ith snarl and kept out of their reach. He did not try to run away, but retreated around and around the camp, advertising plainly that when his desire was met, he would e in and be good. Francois sat down and scratched his head. Perrault looked at his watch and swore. T ime was flying, and they should have been on the trail an hour gone. Francois scratched his head again. He shook it and grinned sheepishly at the courier, who shrugged his shoulders in sign that they were beaten. Then Francois went up to where Solleks stood and called to Buc k. Buc k laughed, as dogs laugh, yet kept his distance. Francois unfastened Sol leks39。 for this was the mail train, carrying word from the world to the men who sought gold under the shadow of the Pole. Buc k did not like it, but he bore up well to the wor k, ta king pride in it after the manner of Dave and Solle ks, and seeing that his mates, whether they prided in it or not, did their fair share. It was a monotonous life, operating with machinelike regularity. One day was very like another. At a certain time each morning the cooks turned out, fires were built, and br eakfast was eaten. Then, while some broke camp, others harnessed the dogs, and they were under way an hour or so before the darkness fell which gave warning of dawn. A t night, camp was m ade. Some pitched the tents, others cut firewood and pine boughs for the beds, and still others carried water or ice for the cooks. A lso, the dogs were fed. To them, this was the one feature of the day, though it was good to loaf around, after the fish was eaten, for an hour or so w ith the other dogs, of which there were fivescore and odd. There were fierce fighters among them, but three battles with the fiercest brought Buck to mastery, so that when he bristled and showed his teeth, they got out of his way. Best of a。 and where judgment was required, and quick thinking and quick acting, he showed himself the superior even of Spitz, of whom Francois had never seen an equal. But it was in giving the law and making his mates live up to it, that Buck excelled. Dave and Solle ks did not mind the change in leadership. It was none of their business. Their business was to toil, and toil mightily, in the traces. So long as that was not interfered with, they did not care what happened. Billee, the goodnatured, could lead for all they cared, so long as he kept order. The rest of the team, however, had grown unruly during the last days of Spitz, and their surprise was great now that Buck proceeded to lick them into shape. Pike, who pulled at Buc k39。 dat Buck fight like two hells, was Francois39。 關于學位論文使用權和研究成果知識產權的說明： 本人完全了解成都信息工程學院有關保管使用學位論文的規(guī)定，其中包括： （ 1）學校有權保管并向有關部門遞交學位論文的原件與復印件。 [7] 李明剛 , 肖建． ASP． NET Web 站點高級編程范例 [M]．北京：清華大學出版社， 2020。例如：許多數字項字段沒有驗證；當編輯用戶信息時，必須強制輸入密碼，確保密碼匹配等等。 結 論 本文主要分析了實現(xiàn)招投標系統(tǒng)的主要方法，并對招投標的主要功能做了描述。 { objItemList = new ()。 //通過 Tools類中的 :public static bool IsLoggedIn()方法 ,并用該方法去判斷用戶是否已經登錄。 [PersonID].Value = ()。 } else if( 1) { = Update Failed! + strStatus。 [].Value = 。 } else { Process = ADD。 = 。 obj = new ()。在首頁面單擊“注冊”鏈接進入該頁面，此頁面不僅可以讓用戶注冊添加個人用戶信息，同時它也是修改注冊信息的界面。database=bids。 表 57 存儲過程表 存 儲 過 程 描 述 sp_bid_isp 添加一條用戶的競價 sp_Get_Bid_Details 獲取某件項目所有競價的詳細信息 sp_item_dsp 刪除某件項目 sp_get_highest_bid 獲取某件項目的最高競價 sp_item_isp 添加一件項目 sp_item_sel 返回某用戶的項目 sp_item_usp 更新某件項目信息 sp_items_for_sale 返回所有可以競價的項目 sp_login 處理用戶登錄事件 sp_my_winning_bids 返回某用戶當前競標于領先地位的所有項目 sp_person_isp 添加一個用戶信 息 sp_person_sel 通過用戶名即郵件地址來查詢一個用戶 sp_person_sel_by_id 查詢某條競標信息的競標者信息 sp_person_usp 更新用戶信息 sp_sale_plete 完成某個項目的交易 sp_sale_isp 為某個項目增加一次成功的交易記錄 6 系統(tǒng)總體實現(xiàn) 本系統(tǒng)使用 Pagelet控件技術編寫了 件。 表 51 系統(tǒng)數據表的簡要描述 表 52 用戶信息表 (Person) 字段名 數據類型 長度 允許為空 是否為主鍵 說明 PersonID bigint 8 否 是 唯一標識 FamilyName varchar 255 否 登錄名 GivenName varchar 255 否 真實名 EmailAddress varchar 255 否 郵箱地址 Password varchar 255 否 密碼 StreetAddress1 varchar 255 否 單位地址 StreetAddress2 varchar 255 是 地址 City varchar 255 是 城市 State varchar 255 是 狀態(tài) PostalCode varchar 10 是 郵政編碼 Country varchar 255 是 所屬國家 Active char 1 是 行為 LastLogin datetime 8 是 最后登錄時間 表 描述 Person 包含系統(tǒng)中所有注冊用戶的資料 Item 包含待售或以售項目的信息 Bid 包含每個 Item出價的信息 Sale 包含每項銷售的信息，包括被出價的項目和出價者 Id Seller 包含 Person出售的項目信息 表 53 Seller表 字段名 數據類型 長度 是否允許為 空 是否為主鍵 說明 ID bigint 8 是 唯一標識 PersonID bigint 8 用戶 ID ItemsListed int 4 所列項目 ItemsActive int 4 活躍項目 LastActivity datetime 8 最后一項活動 表 54 Item表 字段名 數據類型 長度 是否允許為空 是否為主鍵 說明 ItemID bigint 8 是 唯一標識 ItemName varchar 500 項目名稱 Description v
