并且我还发现了巨诡异的事情:在项目文件夹里把HS.ico和bomb.ico的名字互换的话,那么它们显示在文件夹里的图标也会互换!但是打开看了后还是原样的……难道我的电脑成精了?
// here are the icon defines, note the use of C++ comments
ID_ICON_BOMB ICON bomb.ico
ID_ICON_HS ICON HS.ico
这是相关的resources.h的代码:
// File name: resources.h
#define ID_ICON_BOMB 103 // these numbers are arbitrary
#define ID_ICON_HS 104
最后是最主要的代码文件demo3_1.cpp的头文件部分:
#include <windows.h> // include all the windows headers
#include <windowsx.h> // include useful macros
#include <mmsystem.h>
#include <cstdio> // 原版是 #include <stdio.h>
#include <cstdlib> // 原版是 #include <stdlib.h>
#include <cmath> // 原版是 #include <math.h>
#include "resources.h" // include the resource header
然后该文件用到了图标的部分是这里:
winclass.hIcon = LoadIcon(hinstance, MAKEINTRESOURCE(ID_ICON_HS));
// 中间省去无关代码
winclass.hIconSm = LoadIcon(hinstance, MAKEINTRESOURCE(ID_ICON_HS));
可是运行的结果却是任务栏图标是ID_ICON_BOMB,而窗口的图标是默认图标!这个是为什么呀?
