Question

我尝试使用Boost日志库向Windows事件日志发送事件。我为自定义记录器制作了简单的C ++测试应用程序，一切都很好。当我在MFC应用程序中使用记录器时，在EventViewer中可见的生成事件具有此错误

来自源MFCApplication1的事件ID 259的描述不能被发现....

当我在Boost documentation中读到 basic_simple_event_log_backend ＆＃34;包含事件查看器正常运行所需的所有资源，并在Windows注册表中注册Boost.Log库为了将自己填充为这些资源的容器。＆＃34;但我想有些事情失败了。

知道如何在MFC应用程序中使用它吗？我使用的是Boost 1.59 32bit和VS2013。

对于复制，我将MFC应用程序简化为单个cpp文件，没有任何资源：
