四問(wèn)題與解決方案縮放按鈕只能改變畫布大小，不能改變圖片大小解決方案：將畫布的sizemode屬性改為zoom當(dāng)既沒(méi)有畫圖也沒(méi)有加載圖片便點(diǎn)擊保存時(shí)，程序崩潰解決方案：在保存前檢驗(yàn)圖片是否為空，即加入if(myimage!=null)執(zhí)行saveif(myimage!=null){if(saveFileDialog1.ShowDialog()==DialogResult.OK){myimage.Save(saveFileDialog1.FileName,ImageFormat.Bmp);MessageBox.Show("保存成功|");}}list或relist中沒(méi)有對(duì)象時(shí)仍然點(diǎn)擊撤銷或重做，會(huì)使得程序出現(xiàn)錯(cuò)誤，出現(xiàn)功能紊亂解決方案：在執(zhí)行時(shí)檢查對(duì)象數(shù)目，當(dāng)為最后一個(gè)對(duì)象釋放后，控件enable屬性設(shè)為false保存出的圖片一片漆黑解決方案：在load或新建時(shí)g和graphic用clear方法用背景色填充畫弧總是偏離坐標(biāo)解決方案：由于所獲得的mouseposition并不是畫布的坐標(biāo)，所以出現(xiàn)錯(cuò)差，將mouseposition改為newpoint(e.X,e.Y)本地時(shí)間不能同步，只能顯示加載時(shí)的時(shí)間解決方案：添加Timer控件，用tick事件梅1000毫秒觸發(fā)一次，從而實(shí)現(xiàn)本地時(shí)間的同步//顯示本地時(shí)間privatevoidtimer1_Tick(objectsender,EventArgse){toolStripStatusLabel7.Text=Convert.ToString(System.DateTime.Now);}

五設(shè)計(jì)總結(jié)經(jīng)過(guò)一周的課程設(shè)計(jì)，使我對(duì)VisualC#編程有了更深一層的了解。經(jīng)過(guò)編程與不斷調(diào)試，盡管依然存在很多的問(wèn)題，但努力終于有了成果。設(shè)計(jì)的雖然是簡(jiǎn)單畫圖程序，但是對(duì)于我這個(gè)菜鳥來(lái)說(shuō)仍然感覺(jué)代碼很復(fù)雜，深切地感受到想設(shè)計(jì)制作出出色的軟件需要更加努力的學(xué)習(xí)，整個(gè)設(shè)計(jì)的過(guò)程也是不斷學(xué)習(xí)的一個(gè)過(guò)程，在運(yùn)用舊知識(shí)的同時(shí)也學(xué)到了不少新知識(shí)，給自己大腦充電的同時(shí)也填補(bǔ)了一些相關(guān)知識(shí)方面的空白。這幾天在圖書館借的書算是這學(xué)期最多的了，終于明白老師說(shuō)的無(wú)論什么問(wèn)題，一本書上是不可能解釋的很透徹的，為了弄懂一個(gè)問(wèn)題，往往需要找好多和這個(gè)問(wèn)題有關(guān)的資料。整個(gè)設(shè)計(jì)的過(guò)程中，不僅僅只是經(jīng)歷了是失敗與成功所帶來(lái)的啟迪，還有同學(xué)之間互相幫助的友誼。通過(guò)這次課程設(shè)計(jì)，掌握住到了應(yīng)該掌握住的知識(shí)，也讓體會(huì)到了生活中應(yīng)該體會(huì)到的東西?？傊?，這次實(shí)習(xí)是有收獲的。六參考文獻(xiàn)C#開(kāi)發(fā)實(shí)戰(zhàn)1200例清華大學(xué)出版社Visualc#2008開(kāi)發(fā)技術(shù)實(shí)例講解電子工業(yè)出版社VisualC#2008開(kāi)發(fā)技術(shù)詳解電子工業(yè)出版社C#程序設(shè)計(jì)基礎(chǔ)教程與實(shí)驗(yàn)指導(dǎo)清華大學(xué)出版社C#范例開(kāi)發(fā)大全清華大學(xué)出版社C#程序設(shè)計(jì)機(jī)械工業(yè)出版社
