Windows 10: Data Roaming mfc90dll problem

WandaSmalley · Dec 7, 2019

I tried to do a system restore on my computer after a Windows Update. It was unsuccesful, so did a reset on my computer where I saved my files. Now when I try to restart my computer I get the following message C:\Windows.old\Users\"my name"\AppData\Roaming|VERIZON\UA_ar\mfc90.dll I really haven't noticed any problems with any of the programs I use, but my computer does not shut down basically. I can go through the steps to "restart it" and it is like I didn't do anything. After a restart it doesn't have to load the programs....they are already there. Hope this makes sense. I am not the most computer savy person out there.

14MB Data Roaming even though Data Roaming is off

Data Roaming is turned off on my Samsung Focus, but I was just notified by ATT of high international data usage while in the Turks and Caicos Islands (~14MB).

I double checked "Settings->Cellular->Data roaming options", and it is set to "don't roam".

However, I did notice a "3G" symbol on the top status bar on my phone while I was there and did not think anything of it.

Is there some glitch in Windows Phone 7 or the Samsung Focus where data roaming is not properly disabled?

Is it possible my phone did not know I was roaming so it allowed data?

Has this happened to anyone else?

Also, I barely used the phone. What is it doing in the background that could cause 14MB of data to be transfered?

Getting Started with Roaming App Data

Users today are mobile, transitioning from one device to the next throughout the day. Increasingly, these same users expect (or even demand) to take their data with them. Fortunately for us, roaming app data makes this a reality.
Today, we kick off a two-post series that explores how to use roaming app data to give your users a truly mobile experience. In today’s blog post, we’ll explain what roaming data is, how it works, and some ways you can use it in your own app. Finally, we’ll also cover versioning and conflict resolution.

Roaming app data

Roaming app data is the way in which all Universal Windows Platform (UWP) apps keep data in sync across multiple devices. It allows you, the developer, to create apps that help users carry data such as user profiles or documents from one device to the next. Generally speaking, roaming app data breaks down into three main categories:

App data is the data your application requires to function. This data needs to be in sync across all devices.

User data is any data that the user initiates via the application that will synchronize across all devices. For example, if you use your Microsoft account to store Microsoft Office files in the cloud from your desktop and then open Microsoft Office on your laptop, you will be presented with a list of your recent files.

App settings are any configuration settings for an app that will stay in sync across all devices. Think of your profile settings in Visual Studio 2015.

Before we get started digging into the API, it’s important to understand that you have two main points of entry into your roaming app data:

RoamingSettings

RoamingFolder

RoamingSettings

The built-in ApplicationData.RoamingSettings property, which is of the type ApplicationDataContainer, stores its data as a dictionary key/value pair with a string for the key. The key of each setting can be up to 255 characters long and the value for each setting can be no more than 8K bytes in size. Bear in mind, however, that you can only store the following data types:

UInt8, Int16, UInt16, Int32, UInt32, Int64, UInt64, Single, Double

Boolean

Char16, String

DateTime,TimeSpan

GUID, Point, Size,Rect

ApplicationDataCompositeValue

Although you should choose the data type that works best for you and your specific app, ApplicationDataCompositeValue in the above list is the recommended choice. Unlike the other types, which have an 8k-byte limit, this type allows you to store up to 64K bytes. Critically, it also lets you store a subset of settings or categorize your settings...

Data Roaming Cost

Hello Nokia support,

I am using the Lumia 1520, I specifically set MOBILE NETWORK->DATA ROAMING OPTION to " don't roam"

Why is it that data roaming still roam ?

Why is it that I must turn off Data connection to off to totally disconnect from Data roaming?

I have been using Apple/Sumsung phone for many years. Once Data Roaming is turn off, it will not roam!

Turn on Wifi and turn off DATA Connection do not make sense, because Wifi = Data connection!

This is apparently a design fault and caused me to pay $100 on data roaming unnecessary!

I think users who are converting back to Nokia from Android phone will find this a problem!
