WPF - 从非托管旧版C ++代码中捕获错误

Question

我是一个为UI构建WPF应用程序的团队，同时重用了最初在C ++ / OpenGL中开发的大部分核心应用程序（图形处理和3d建模）。我面临的问题是我似乎无法捕获从C ++层抛出的异常。我对WPF应用程序进行了全局错误处理，它确实捕获了所有未处理的C＃异常。我需要做类似的事情来捕获C ++异常，但到目前为止我还没有能够让它工作。代码如下。

    public partial class App : Application
    {
        private static readonly Logger Logger = LogManager.GetCurrentClassLogger();

        /// <summary>
        /// Overrides Application.OnStartup to register the global exception handler
        /// </summary>
        /// <param name="e"></param>
        protected override void OnStartup(StartupEventArgs e)
        {
            Application.Current.DispatcherUnhandledException +=
                new System.Windows.Threading.DispatcherUnhandledExceptionEventHandler(Application_DispatcherUnhandledException);
            AppDomain.CurrentDomain.UnhandledException += AppDomain_UnhandledException;
            base.OnStartup(e);
        }

        private void AppDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            Logger.Error("Application encountered an unhandled exception", e.ExceptionObject.ToString());
            GenericDialog genericDialog = new GenericDialog(OmegaConstant.DialogType.Error, 
                String.Format("Application has encountered an unhandled exception leaving the application in an unstable state. Error: {0}", 
                e.ToString()), 900);
            genericDialog.ShowDialog();
            Logger.Error("Application is shutting down");
            Application.Current.Shutdown();
        }

        /// <summary>
        /// Hanndles all uncaught exceptions from C# layer
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void Application_DispatcherUnhandledException(object sender,
            System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
        {
            Logger.Error("Application encountered an unhandled exception", e.Exception);
            GenericDialog genericDialog = new GenericDialog(OmegaConstant.DialogType.Error, 
                String.Format("Application has encountered an unhandled exception leaving the application in an unstable state. Error: {0}", 
                e.Exception.Message), e.Exception, true, 900);
            genericDialog.ShowDialog();
            e.Handled = true;
            Logger.Error("Application is shutting down");
            Application.Current.Shutdown();
        }
    }
