MFC課程設(shè)計(jì)調(diào)整對(duì)話框背景顏色

1、mfc課程設(shè)計(jì)課題名稱：調(diào)整對(duì)話框背景顏色專業(yè)班級(jí)：1020562班學(xué)生學(xué)號(hào)：學(xué)生姓名： 指導(dǎo)教師： 提交時(shí)間：2011年12月10日目錄1.設(shè)計(jì)描述31.1課題背景31.2功能描述32.設(shè)計(jì)分析42.1應(yīng)用的類42.2成員函數(shù)43.源代碼及圖形64.設(shè)計(jì)總結(jié)174.1個(gè)人心得174.2參考文獻(xiàn)171.設(shè)計(jì)描述1.1課題背景 本課題主要是在為了讓自己更加了解在mfc中框架類中的各種函數(shù)的應(yīng)用。本程序是在vc6.0中使用appwizard創(chuàng)建基于對(duì)話框的應(yīng)用程序。1.2功能描述本程序能夠改變對(duì)話框的背景顏色。對(duì)話框中有滾動(dòng)條和滑動(dòng)塊，通過調(diào)節(jié)滾動(dòng)條或滑動(dòng)塊來改變對(duì)話框的背景顏色。除此以外，該對(duì)話

2、框可以最小化，最大化功能。點(diǎn)擊關(guān)閉按鈕時(shí)，會(huì)出現(xiàn)提示對(duì)話框，提示對(duì)話框中有“退出應(yīng)用程序”，“返回到托盤”，“不再提示”選擇按鈕供你選擇。另外托盤圖標(biāo)是閃動(dòng)變換的，托盤圖標(biāo)還可以打開子菜單。最小化：最大化：2.設(shè)計(jì)分析本程序用到了一些基于對(duì)話框的類，實(shí)現(xiàn)對(duì)話框的各種功能2.1應(yīng)用的類圖2.1 classview2.2成員函數(shù)程序里的成員函數(shù)如下1、bool cwlhdlg:oninitdialog()2、void cwlhdlg:onhscroll(uint nsbcode, uint npos, cscrollbar* pscrollbar) 3、hbrush cwlhdlg:onctlco
