	// 资源
	// 
	// Usage:
	//     Resource 用于获取可执行文件 (exe) 中的资源, 必须在构造函数中指定它的
	//     资源类型和名称标识符。
	//     例如, 一份音频资源的类型为 L"WAVE", 名称标识符为 IDR_WAVE_1, 那么可以这样指定该资源:
	//     Resource res(MAKEINTRESOURCE(IDR_WAVE_1), L"WAVE");
	//     如果需要手动加载这份资源, 可以通过 Load 方法获取资源内容
	//     if (res.Load()) {
	//         LPVOID data = res.GetData();
	//         DWORD size = res.GetDataSize();
	//     }
	//     了解资源的更多信息: https://docs.microsoft.com/en-us/windows/desktop/menurc/resources
