練習(xí)使用圖標(biāo)，菜單，加速鍵，消息框等資源。
1. 圖標(biāo)（注冊類時使用自己畫的大圖標(biāo)和小圖標(biāo)）。
2. 菜單（設(shè)計一個菜單，能控制動態(tài)改變圖標(biāo)(3選1單選），在四個位置顯示大圖標(biāo)（復(fù)選），“關(guān)于”）。
3. 加速鍵（每個菜單項都有加速鍵）。
4. 消息框（改變圖標(biāo)前確認(rèn)是否要修改, About）。
5. 顯示菜單前動態(tài)生成一個下拉菜單，加入到主菜單中(File下Exit,位置0), 也要處理加速鍵。
6.選擇圖標(biāo)3時復(fù)選菜單灰化，不顯示復(fù)選大圖標(biāo)。
實(shí)現(xiàn)功能 5 時，自己查MSDN
CopyAcceleratorTable
CreateAcceleratorTable
DestroyAcceleratorTable
1. 我最初是在Win7寫此程序，動態(tài)改動標(biāo)題欄圖標(biāo)時，使用 ::SetClassLong( hWnd, GCL_HICON, (long)(hIcon) ); 沒有效果，仔細(xì)看老師的ppt，確實(shí)是這么講的，然后到 MSDN 中查閱 SetClassLong 函數(shù)時，看到 GCL_HICONSM，我猜測是因?yàn)槲业拇翱陬悶?WNDCLASSEX，其中大小圖標(biāo)是有區(qū)別的，應(yīng)該用 GCL_HICONSM ，于是我調(diào)用 ::SetClassLong( hWnd, GCL_HICONSM, (long)(hIcon) ); 標(biāo)題欄的小圖標(biāo)可以修改了。然而回到WinXP繼續(xù)開發(fā)時，標(biāo)題欄圖標(biāo)又無法修改了，以為是WinXP下不支持24位圖標(biāo)，改為4位，無效。大小圖標(biāo)分別建立資源，依然無效。最后將窗口類換為 WNDCLASS 后，SetClassLong 可以正常工作。
2. 設(shè)置加速鍵時，對 Ctrl + 1 這種有數(shù)字的加速鍵，我誤用了小鍵盤的數(shù)字鍵 Ctrl + numpad1，后來才發(fā)現(xiàn)。
截圖：
程序信息消息框：
圖標(biāo)類型 1
圖標(biāo)類型 1 時，顯示圖標(biāo)
換圖標(biāo)時的詢問對話框：
換為圖標(biāo) 3 時，不顯示復(fù)選大圖標(biāo)
換為圖標(biāo) 3 時，復(fù)選菜單無效灰化
鍵盤加速鍵都可以正常工作。
