效果图：

 第一步：

创建一个.rc文件，如我再代码根目录下创建了一个myApp.rc文件和准备一张ICO图标

 内容为：

 IDI_ICON1   ICON   DISCARDABLE   "csdn.ico"
 
 #if defined(UNDER_CE)
#include <winbase.h>
#else
#include <winver.h>
#endif
 
VS_VERSION_INFO VERSIONINFO
    FILEVERSION 1,0,0,0
    PRODUCTVERSION 1,0,0,0
    PRODUCTVERSION 1,0,0,0
    FILEFLAGSMASK 0x3fL
#ifdef _DEBUG
    FILEFLAGS VS_FF_DEBUG
#else
    FILEFLAGS 0x0L
#endif
    FILEOS VOS__WINDOWS32
    FILETYPE VFT_DLL
    FILESUBTYPE 0x0L
    BEGIN
        BLOCK "StringFileInfo"
        BEGIN
            BLOCK "080404b0"
            BEGIN
                VALUE "CompanyName", "XzpBlog Technology Co.Ltd.\0"
                VALUE "FileDescription", "CsdnDemo.exe\0"
                VALUE "FileVersion", "1.0.0.0\0"
                VALUE "ProductVersion", "1.0.0.0\0"
                VALUE "LegalCopyright", "Copyright (C)2010-2020\0"
                VALUE "LegalTrademarks", "XzpBlog Technology Co.Ltd.\0"
                VALUE "OriginalFilename", "CsdnDemo.exe\0"
                VALUE "ProductName", "CsdnDemo.exe\0"
                VALUE "InternalName", "CsdnDemo.exe\0"
           END
        END
        
        BLOCK "VarFileInfo"
        BEGIN
            VALUE "Translation", 0x804, 1200
        END        
    END

第二步：

在.pro文件中添加

RC_FILE  = myApp.rc

重新编译就可以了
