VC++實訓(xùn)--學(xué)生信息管理系統(tǒng)

1、信息科學(xué)與工程學(xué)院報告書專 業(yè)：計算機(jī)科學(xué)與技術(shù)課程 名稱：VC+實訓(xùn)題 目：學(xué)生信息管理系統(tǒng)班 級：設(shè) 計 者：完 成 時 間：總 成 績教師簽名學(xué)生信息管理系統(tǒng)一 系統(tǒng)總體方案系統(tǒng)基本實現(xiàn)了對學(xué)生信息的查詢，添加，修改，刪除，保存功能。二 設(shè)計思路和主要步驟思路主要是設(shè)計一個單文檔用來實現(xiàn)主界面，然后在菜單欄添加一個菜單項，下面包含錄入學(xué)生基本信息，查詢學(xué)生基本信息，和修改學(xué)生基本信息等多項子菜單，每項子菜單都對應(yīng)一個對話框?qū)?shù)據(jù)進(jìn)行處理。在主對話框中添加列表控件用來顯示學(xué)生的基本信息，以方便學(xué)生信息的修改，具體修改哪一項。對于學(xué)生信息的錄入，查詢，修改，刪除都用按鈕控件，并為每個按鈕添加

2、消息響應(yīng)函數(shù)用來處理學(xué)生的信息操作。接下來就是要把學(xué)生的基本信息能夠保存下來，因此要用到文件的操作，fstream可以滿足要求。綜上所述，必須先掌握按鈕控件，列表控件，新對話框的構(gòu)建，編輯控件和消息的響應(yīng)與處理原理！三 各功能模塊和流程圖1.功能模塊實現(xiàn) 主界面 對話框一 對話框2 對話框3四 設(shè)計代碼1.主體框架代碼：int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)if (CFrameWnd:OnCreate(lpCreateStruct) = -1)return -1;if (!m_wndToolBar.CreateEx(this
