How to use High priority setting app settings

Question

Hi all,

http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.applicationdata.roamingsettings.aspx
Follow this page,
I want use HighPriority in my app.
But, I have two questions.

Question1:
HighPriority's value should be int or String? large number or small number?
What's the function that about HighPriority's value?
ex: 
RoamingSettings->Values->Insert("HighPriority", PropertyValue::CreateString("1"));

Question2:
follow this link
"High priority roaming works only with one setting, so if you need to roam multiple pieces of data such as an article and a page number you can use a composite value"
Depend on this article, the roaming file and HighPriority it's no correlation

Thanks

Hi,

For first question, this is how you can create a HighPriority simple value-setting pair :-

ApplicationDataContainer roamingSettings =  ApplicationData.Current.RoamingSettings;
roamingSettings.Values["HighPriority"] = "Sample_High_Priority_value";

For second question, HighPriority is one setting, which means can contain either a simple or a composite object.

An HighPriority composite object can be made in the following way :-

ApplicationDataContainer roamingSettings =  ApplicationData.Current.RoamingSettings;
roamingSettings.Values["HighPriority"] = "Sample_High_Priority_value";
ApplicationDataCompositeValue composite = new ApplicationDataCompositeValue();
composite["HP_settingName1"] = 1; // example value
composite["HP_settingName2"] = "world"; // example value

roamingSettings.Values["HighPriority"] = composite;

Hi,

Thanks for your reply.

For first question 2,
If I want roaming a playlist file,
I can put this file in ApplicationData::Current->RoamingFolder.
So, the HighPriority and roaming file is no correlation?

Add one question,
Question3:
Where the location of our roaming file or settings in MSFT server?
Could I remove these by Browser or other tools?

For example:
I have roaming a playlist file between two devices.
So, I know that the MSFT server should be have my playlist file
Can I remove this file by other path(Browser...etc)?

Thanks

As of now, HighPriority is associated to RoamingSettings. "HighPriority" is a KEY for a value (which can be your playlist file). The storage for Roaming Settings is designed to facilitate roaming data usage independent of a particular server, so that users can have a seamless experience wherever they are. You can directly modify the roaming settings data using the ApplicationData::Current->RoamingFolder object.
