How to get Device ID ??

Question

Hi , 

How can I get the Device Unique ID for my tablet surface ?

I found this

http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.enumeration.deviceinformation.aspx

and also I have implemented the EnumerateDeviceContainers from Microsoft Sample.

                                       

  string[] properties = { "System.ItemNameDisplay", "System.Devices.ModelName", "System.Devices.Connected" };
            var containers = await PnpObject.FindAllAsync(PnpObjectType.DeviceContainer, properties);




            foreach (PnpObject container in containers)
            {
                MyDisplayItems.Add(new DisplayItem(container));
            }

and the Class

 class DisplayItem

    {
        public DisplayItem(PnpObject container)
        {
            name = (string)container.Properties["System.ItemNameDisplay"];
            if (name == null || name.Length == 0)
            {
                name = "*Unnamed*";
            }

            id = container.Id;
            properties += "Property store count is: " + container.Properties.Count + "\n";
            foreach (var prop in container.Properties)
            {
                properties += prop.Key + " := " + prop.Value + "\n";
            }
        }

        public string Id { get { return id; } }
        public string Name { get { return name; } }
        public string Properties { get { return properties; } }

        readonly string id;
        readonly string name;
        readonly string properties;
    }

Exactly like the example.   But the MyDisplayItems[0].Id , the first Item of the collection Contains zeroes and FFs. The other Ids  have numbers etc.  How Can I get my tablet's device ID ? Am I doing something wrong ? Appreciate any help you could give me. Thank you

Answer 1

there isnt such id available so far i know. you will have to generate one your self

Answer 4

OK.

If I use the MyDisplayItems[1].Id(refers to the USB massive storage)  which has something, will it be unique ?

Answer 5

Check this out : HardwareIdentification.GetPackageSpecificToken. Not sure whether its always unique, just give it a try if needed.

Answer 6

before jumping into conclusions, did you have a look at the HardwareIdentification class? It is supposed to provide (from MSDN link):

"Application Specific Hardware Identifier (ASHWID for short) in conjunction with its back-end service to implement per-device logic. Apps that employ per-device licensing policies are examples of apps that belong to this category. "

So something like:

var packageSpecificToken = Windows.System.Profile.HardwareIdentification.GetPackageSpecificToken(null);

// hardware id, signature, certificate IBuffer objects 
// that can be accessed through properties.
IBuffer hardwareId = packageSpecificToken.Id;
IBuffer signature = packageSpecificToken.Signature;
IBuffer certificate = packageSpecificToken.Certificate;

var deviceID = BitConverter.ToString(hardwareId.ToArray());

would actually provide you a token for that specific device if you want to implement a per-device logic in your implementation.

But please correct me if I am wrong...
