操作系統(tǒng)課程設(shè)計(jì)報(bào)告-模擬文件管理系統(tǒng)（附源程序）

1、源程序代碼，聯(lián)系153893706操作系統(tǒng)課程設(shè)計(jì)報(bào)告題目: 模擬文件管理系統(tǒng)學(xué) 院 計(jì)算機(jī) 專(zhuān) 業(yè) 網(wǎng)絡(luò)工程 年級(jí)班別 1班 學(xué) 號(hào) 學(xué)生姓名 指導(dǎo)教師_ _ 成 績(jī) 2007 年 1 月 一、課程設(shè)計(jì)題目：編寫(xiě)并調(diào)試一個(gè)樹(shù)型目錄結(jié)構(gòu)的文件系統(tǒng)，模擬文件管理工作流程。要求：(1)設(shè)計(jì)多用戶(hù)文件系統(tǒng)，采用多級(jí)文件目錄。(2)至少要有十個(gè)以上的實(shí)用命令，應(yīng)設(shè)置文件保護(hù)措施。(3)設(shè)計(jì)一個(gè)較實(shí)用的用戶(hù)界面，方便用戶(hù)使用，界面要為用戶(hù)提供足夠的選擇信息，不需用戶(hù)打入打入冗長(zhǎng)的命令。二、設(shè)計(jì)思想說(shuō)明：使用可視化環(huán)境編程，程序界面模仿windows系統(tǒng)的資源管理器程序左邊為目錄樹(shù)形結(jié)構(gòu)，顯示多級(jí)文件目錄

2、，右邊為目錄內(nèi)容顯示。使用鼠標(biāo)，鍵盤(pán)，快捷鍵及拖動(dòng)作各種文件的操作。文件操作功能有：用戶(hù)登錄，新建文件夾，新建文件，文件重命名，剪切文件/文件夾，復(fù)制文件/文件夾，粘貼，查看文件內(nèi)容，修改文件內(nèi)容，查看文件屬性，修改文件權(quán)限等。為了便于操作，系統(tǒng)內(nèi)的所有文件文件類(lèi)型默認(rèn)為文本文件，用戶(hù)可以直接編輯其文字內(nèi)容。三、系統(tǒng)結(jié)構(gòu)的說(shuō)明1.開(kāi)發(fā)環(huán)境：2.運(yùn)行環(huán)境： Windows 98/NT4.0 以上3.使用控件：Tmenu 菜單欄控件TImageList 圖表集控件 TTreeView 樹(shù)形結(jié)構(gòu)顯示控件 TListView 對(duì)象顯示控件 TPopUpMenu 反健菜單控件 TSplitter 工具欄

3、按鈕分割控件 TStatusBar 狀態(tài)欄控件 TToolButton 工具欄按鈕控件 TToolBar 工具欄菜單控件4.窗體結(jié)構(gòu)： 如下列圖，窗體分為三個(gè)，分別是Form1，F(xiàn)orm2，F(xiàn)orm3。其中Form1位程序主界面窗體，為始終顯示狀態(tài)；Form2為文件內(nèi)容顯示及修改窗體，翻開(kāi)文件時(shí)顯示，其他時(shí)候?yàn)殡[藏狀態(tài)；Form3為文件屬性窗體，查看文件屬性時(shí)為顯示狀態(tài)，其他時(shí)候?yàn)殡[藏狀態(tài)。Form1,Form2,Form3之間互相包含頭文件，以便于傳遞數(shù)據(jù)。 圖表一 Form1 圖表二 Form2 圖表三 Form3函數(shù)設(shè)置：Form1：int all_size(); /統(tǒng)計(jì)ListView
