更改标题栏图标时如何正确使用loadicon和makeintresource？ [英] How do i use loadicon and makeintresource correctly when changing the title bar icon?

问题描述

我正在使用Code：Blocks c ++ win32中的一个项目。我已经在互联网上阅读了LoadIcon和MAKEINTRESOURCE的使用。但是，似乎我没有正确使用它们。我用油漆创建了一个图像并命名为'ico1'。它的格式为'.png'。



当我执行程序时，我在第1行收到错误代码错误：在'1002'中请求成员'png'，这是非类型的'int'。



以下是代码。

I am working on a project in Code:Blocks c++ win32. I have read on the internet the use of LoadIcon and MAKEINTRESOURCE. However, it seems I am not using them correctly. I have created an image with paint and named it 'ico1'. It is in the format '.png'.

When I execute the program I get an error code at line 1 "error: request for member 'png' in '1002', which is of non-class type 'int'."

Below is the code.

/* Use default icon and mouse-pointer */
    wincl.hIcon   = LoadIcon (ico1.png, MAKEINTRESOURCE(IDI_ico1));
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL;                 /* No menu */
    wincl.cbClsExtra = 0;                      /* No extra bytes after the window class */
    wincl.cbWndExtra = 0;                      /* structure or the window instance */
    /* Use Windows's default colour as the background of the window */
    wincl.hbrBackground = (HBRUSH) COLOR_HIGHLIGHTTEXT;

接下来我该怎么办？任何帮助深表感谢。谢谢。



我尝试过：



#define IDI_ico1 1001

#define ico1 1002



/ *使用默认图标和鼠标指针* /

wincl.hIcon = LoadIcon（ico1.png，MAKEINTRESOURCE（IDI_ico1））;

wincl.hIconSm = LoadIcon（NULL，IDI_APPLICATION）;

wincl.hCursor = LoadCursor（NULL，IDC_ARROW） ;

wincl.lpszMenuName = NULL; / *没有菜单* /

wincl.cbClsExtra = 0; / *窗口类后没有额外的字节* /

wincl.cbWndExtra = 0; / *结构或窗口实例* /

/ *使用Windows的默认颜色作为窗口的背景* /

wincl.hbrBackground =（HBRUSH）COLOR_HIGHLIGHTTEXT;

What should I do next? Any help is much appreciated. Thanks.

What I have tried:

#define IDI_ico1 1001
#define ico1 1002

/* Use default icon and mouse-pointer */
wincl.hIcon = LoadIcon (ico1.png, MAKEINTRESOURCE(IDI_ico1));
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
wincl.lpszMenuName = NULL; /* No menu */
wincl.cbClsExtra = 0; /* No extra bytes after the window class */
wincl.cbWndExtra = 0; /* structure or the window instance */
/* Use Windows's default colour as the background of the window */
wincl.hbrBackground = (HBRUSH) COLOR_HIGHLIGHTTEXT;

推荐答案

LoadIcon功能（Windows） [ ^ ]要求使用Windows图标格式将图像作为资源存储在可执行文件或加载的DLL中。



如果要从文件加载图标，可以使用 LoadImage函数（Windows） [ ^ ]，带 LR_LOADFROMFILE 。但即使是这个函数也要求文件是Windows图标或位图文件。因此，您必须将PNG文件转换为支持的格式之一。

LoadIcon function (Windows)[^] requires the image to be stored as resource in the executable or a loaded DLL using the Windows icon format.

If you want to load an icon from a file you can use the LoadImage function (Windows)[^] with LR_LOADFROMFILE. But even this function requires the file to be a Windows icon or bitmap file. So you must convert your PNG file to one of the supported formats.
