Each time when shutting down W7, I have been getting the above error since about a week. Today I realized it was caused by the latest GarminExpress V3.2.21.0. So unclicked it in the msconfig /Startup/Express Tray, pressed OK and rebooted the PC.

What caused it I do not know.

  • It may be a .Net Framework or WPF issue that is causing the error.

    However, a new version of Garmin Express was released yesterday. I would suggest updating to version 3.2.22, when Express is open click on the gear icon and check for updates, to see if that resolves the problem.

    If the problem persists download and run Microsoft’s .NET Framework Repair Tool:

  • Thanks Trish. Did both things as you suggested and problem has gone although which action cured the problem I can’t tell.

Microsoft Azure

Few days ago was released a new version of the Windows Azure Media Services .NET SDK, the version 2.2.0.1 that can be downloaded via the NuGet Packages Manager Console (see http://nuget.org/packages/windowsazure.mediaservices). One of the top feature in this release is the ability to create notification endpoints to be notified when a job state change occurs !

In the previous versions of the SDK, the only way to track job state changes was to keep a list of all job’ ids (in a sql server table, for example) and pull each job through the CloudMediaContext to get its state. This solution works fine but is not really elegant or scalable when dealing with multiple azure worker, for example. Now, it’s possible to create a notification endpoint linked to a Windows Azure Storage Queue and pull this queue instead of the media context. It’s the Windows Azure Media Service backend that manage the messages that are pushed in this queue.

To use the notification endpoints, you need to create a CloudQueue that will be used for notification endpoint(s) :

//create the cloud storage account from name and private key
CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(StorageConnectionString);

//create the cloud queue client from the storage connection string
CloudQueueClient cloudQueueClient = cloudStorageAccount.CreateCloudQueueClient();

//get a cloud queue reference
CloudQueue notificationsQueue = cloudQueueClient.GetQueueReference(NotificationQueuePath);

//create the queue if it does not exist
if (!notificationsQueue.Exists())
{
notificationsQueue.Create();
}

Now, you can use the CloudMediaContext to create an instance of INotificationEndpoint, the new interface that enables notifications management :

//create the Cloud Media Context
CloudMediaContext mediaContext = new CloudMediaContext("<mediaservicename>", "<mediaservicekey>");

//create a notification endpoint
INotificationEndPoint notificationEndpoint =
mediaContext.NotificationEndPoints
.Create("notificationendpoint", NotificationEndPointType.AzureQueue, NotificationQueuePath);

As you can see, the Create method take a NotificationEndPointType as second parameter. For now, the only possible value (instead of None) is AzureQueue. It may seems that future releases of the SDK will support Azure Service Bus queue or topics ? (I really don’t know, but it will be very cool ! )

Once the notification endpoint has been created, you can create the job and all the tasks it should execute as usual :

//create an asset
IAsset asset = mediaContext.Assets.Create("Wildlife HD", AssetCreationOptions.None);

//create an asset file from the sample video file
string fileName = System.IO.Path.GetFileName(VideoTestPath);
IAssetFile assetFile = asset.AssetFiles.Create(fileName);

//upload the asset
assetFile.Upload(VideoTestPath);

//create a media service job
IJob mediaServiceJob = mediaContext.Jobs.Create("Wildlife in HD Adaptive Streaming");

//get the latest Windows Azure Media Encoder
IMediaProcessor mediaProcessor = GetLatestsAzureMediaEncoder(mediaContext);

//create a multi bitrate encoding task
ITask multibitrateTask = mediaServiceJob.Tasks.AddNew("Multibitrate MP4 encoding", mediaProcessor, "H264 Adaptive Bitrate MP4 Set 720p", TaskOptions.None);

//add the asset as input of the task
multibitrateTask.InputAssets.Add(asset);

//create the output asset
multibitrateTask.OutputAssets.AddNew("Wildlife HD Output", AssetCreationOptions.None);

Before submitting the job, you have to declare the association with the notification endpoint. To do that, a new property has been added on the IJob interface : JobNotificationsSubscriptions. Call AddNew on this property to link the notification endpoint to the job :

mediaServiceJob.JobNotificationSubscriptions.AddNew(NotificationJobState.FinalStatesOnly, notificationEndpoint);

Now, you can submit the job :

mediaServiceJob.Submit();

Et voilà ! To be notified of each job state change you just need to pull the CloudQueue :

while (continuePull)
{
Thread.Sleep(5000);//sleep for 5 sec

//get a cloud queue message
CloudQueueMessage message = notificationsQueue.GetMessage();
if (message == null)//if null, continue
continue;
}

The message content is serialized as json so you can use the DataContractJsonSerializer to get an object that as this prototype :

public class EncodingJobMessage
{
public String MessageVersion { get; set; }

public String EventType { get; set; }

public String ETag { get; set; }

public String TimeStamp { get; set; }

public IDictionary<string, object> Properties { get; set; }
}

The EventType property can take two values :

  • JobStateChange : indicates that the notification message is related to a job state change

  • NotificationEndpointRegistration : indicates that the notification endpoint has been registered

The Properties property is a dictionary that contains different information about the notification event :

  • JobId : the id of the job

  • NewState : the new state

  • OldState : the old state

  • NotificationEndpointId : the id of the notification endpoint

  • State : the state of the notification endpoint (Registered or Unregistered)

Here is a sample of message deserialization using the DataContractJsonSerializer :

//get the bytes
using (MemoryStream ms = new MemoryStream(message.AsBytes))
{
//deserialize the message
DataContractJsonSerializerSettings jsonSerializerSettings = new DataContractJsonSerializerSettings();
jsonSerializerSettings.UseSimpleDictionaryFormat = true;

DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(EncodingJobMessage), jsonSerializerSettings);
EncodingJobMessage jobMessage = (EncodingJobMessage)serializer.ReadObject(ms);

//if the event type is a state change
if (jobMessage.EventType == "JobStateChange")
{
//try get old and new state
if (jobMessage.Properties.Any(p => p.Key == "OldState") && jobMessage.Properties.Any(p => p.Key == "NewState"))
{
string oldJobState = jobMessage.Properties.First(p => p.Key == "OldState").Value.ToString();
string newJobState = jobMessage.Properties.First(p => p.Key == "NewState").Value.ToString();

Console.WriteLine("job state has changed from {0} to {1}", oldJobState, newJobState);
}
}
}

This new feature is really cool and allows more flexible and scalable architecture when dealing with Windows Azure Media Services jobs !

Hope this helps

Центр действий и уведомлений в Windows 10  сообщает пользователю обо всех важных событиях, таких как обновления, предупреждения об обслуживании, безопасности и др. Некоторые пользователи сообщают, что после обновления Windows 10 «Обновление октября 2018 года», версия 1809, система не показывает уведомления в Центре действий. Вот краткое решение.

Когда Центр действий получает новое уведомление, он показывает всплывающий баннер с уведомлением над панелью задач. Если вы пропустите уведомление, оно будет сохранено в очереди сообщений в Центре действий.

Центр действий не показывает уведомления в Windows 10

Одна из проблем, возникающих в Windows 10, заключается в ошибке Центра действий и уведомлений. Проблема, похоже, связана с функцией Windows 10  — «Фоновые приложения». Если вы столкнулись с данной проблемой, выполните следующие действия.

Центр действий не показывает уведомления в Windows 10 версии 1809

Откройте приложение «Параметры». Перейдите в раздел «Конфиденциальность» →  «Фоновые приложения».

Убедитесь, что у вас есть включена опция  «Разрешить приложениям работать в фоновом режиме». Если опция отключена, вы должны включить ее.

В случае, если указанная опция включена, но уведомления Центра действий по-прежнему не работают, вы должны попробовать следующее.

  1. Откройте «Параметры».
  1. Перейдите в раздел «Конфиденциальность» →  «Фоновые приложения».

Разрешить приложениям работать в фоновом режиме

  1. Выключите опцию  «Разрешить приложениям работать в фоновом режиме».
  1. Перезагрузите Windows 10.
  1. После перезагрузки ПК снова откройте «Параметры» и включите указанную опцию.
  1. Перезагрузите операционную систему.

Эта последовательность должна восстанавливать показ уведомлений.

По умолчанию некоторые универсальные приложения уже включены для запуска в фоновом режиме в Windows 10. Будильник и часы, фотографии, магазин и некоторые другие приложения настроены на работу в фоновом режиме.

Поэтому необходимо, чтобы функция была включена и настроена правильно.

Если у вас остались проблемы с уведомлениями для любых приложений в Windows 10, есть очень простое решение.

Нужно сбросить значение раздела реестра PushNotifications по следующему пути:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\PushNotifications

Чтобы сэкономить ваше время мы подготовили готовый Reg файл.

1. Скачайте архив FixPushNotifications (фиксация отсутствия Уведомлений в Windows 10). 

2. Извлеките файл FixPushNotifications.reg из архива и дважды кликните на нем.

3. Вам будет показано предупреждение: нажмите «Да».

FixPushNotifications

4. Перезагрузите компьютер.

После импорта и перезагрузки компьютера,  перейдите «Параметры» →  «Система» →  «Уведомления и действия» и включите опцию «Получать уведомления от этих приложений» для приложений в списке.

Уведомления и действия

Это также поможет в случае если приложение есть в списке, но уведомления не показываются, несмотря на правильные настройки.

    New Windows Media Player Plugin for Firefox

    Anyone who uses Windows Vista and Mozilla Firefox may be pleased to hear that the Windows Media Player team has now released a plugin for Firefox that should allow the browser to play WMP content on websites. Here are the steps to get it working:

    • Installation of the Windows Media Player Firefox Plugin may require administrative access to your PC. It is recommended that you close all other open browser windows before continuing with the installation.
    • Click the Install button to automatically download and install the Windows Media Player Firefox Plugin.
    • Depending on your security settings, you may see a Security Warning dialog box. Click Install to install the plugin.

    There is a known issue if you are using Firefox version 2.0.0.3 on Windows Vista with the installer failing with error code -203. To work around this simply restart Firefox (you will get a notification that Windows Vista will be changing the Firefox compatibility settings) and then install again — the second time should succeed.

    The download is available here, and the new plugin works on all versions of Windows XP and Windows Vista (although it is mostly intended for Vista, as that currently has no WMP support in Firefox).
