LoadIcon的使用
LoadIcon
msdn:
Loads the specified icon resource from the executable (.exe) file associated with an application instance.
Syntax
HICON WINAPI LoadIcon( _In_opt_ HINSTANCE hInstance, _In_ LPCTSTR lpIconName );
Parameters
Type: HINSTANCE
A handle to an instance of the module whose executable file contains the icon to be loaded. This parameter must be NULL when a standard icon is being loaded.
Type: LPCTSTR
The name of the icon resource to be loaded. Alternatively, this parameter can contain the resource identifier in the low-order word and zero in the high-order word. Use the MAKEINTRESOURCE macro to create this value.
To use one of the predefined icons, set the hInstance parameter to NULL and the lpIconName parameter to one of the following values.
在初始化时,我们可以这样使用:
wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION) ;
使用系统预定义图标,必须把第一个参数设置为NULL.
相应的显示:
另外,我们也可以使用自定义的图标:
用到MAKEINTRESOURCE宏
MAKEINTRESOURCE
Converts an integer value to a resource type compatible with the resource-management functions. This macro is used in place of a string containing the name of the resource.
Syntax
LPTSTR MAKEINTRESOURCE( WORD wInteger );
Parameters
- wInteger
-
The integer value to be converted.
在VS2012下的Resource View下的项目添加ICO文件,它会生成ID号,默认的IDI_ICON1.
引入resource.h
修改如下:
wndclass.hIcon = LoadIcon (hInstance, MAKEINTRESOURCE(IDI_ICON1)) ;
