That's great. I'll install it via Nuget on the new apps I'll be working on.

Thanks.

New Post: Serialization of custom class

mercurygal — Tue, 05 Feb 2013 18:37:45 GMT

No problem, I suspected that might be the case!

The problem doesn't seem to occur with a string object type (not that there aren't other problems) but any other custom class I create throws the same error. It's okay, I was more wondering if you'd come across it before! I'll keep digging, in the morning when I have stopped hating the sight of code! :)

Thanks anyway!

New Post: Serialization of custom class

Hi mercurygal,
Oh dear. I wish I had a simple answer for you but I'm afraid I do not. While I did build ObjectStorageHelper I must confess that .Net development is not my strongpoint - in fact part of the reason for building ObjectStorageHelper was to further my own limited knowledge.

From what you have said I really can't understand why this is happening. Does it happen if you use a different class other than person for T?

Jamie

New Post: Serialization of custom class

Hi,

While I understand this may not be a problem with your code, as I'm out of ideas this is a last ditch attempt for help, but using the ObjectStorageHelper for a custom class "person", I keep encountering this error on the line where I declare the ObjectStorageHelper:

"System.Runtime.InteropServices.WindowsRuntime.RuntimeClass is inaccessible due to its protection level. Only public types can be processed."

From research I understand that this ought to relate to my class but I can't see anything that isn't public:

public class person
        {
            public string myName;
            public string myPhonenum;

            public person() { }
        }

So I was more wondering if you'd encountered this error at any point during development and could offer any advice?

Thanks for any feedback and much appreciation for this tool!

New Post: Property type not string or int but point to another class, can I still Serialize the object?

Hi,

If ClassRoom is serializable then yes, I believe you should be able to do this. There's only one way to know for sure of course, try it out :)

I have a class(for instance Student) which has a property (its property type is not string or int) pointing to another class (for instance Classroom), can I still Serialize objects created from class Student?

New Post: Using ItemCollection

Jamie…Thanks for the reply.

I don’t know if the error code is all that relevant. It depends on which incorrect code I try J I think it boils down to the my ItemCollection isn’t look at as a List of T. I actually get an error in constructing ObjectStorageHelper.

var osh = new ObjectStorageHelper<List<RealActiv>>(StorageType.Local);

RealActiv is my class that contains the ItemCollection

I’ve tried all kinds of things….I’m even currently messing around with _realActiv.Collection.OfType<RealActiv>().ToList()

Any advice…greatly appreciated.

Thanks

Steve

Hi Steve,

Hmmm...thanks for letting me know. What's the error that you receive?

New Post: Using ItemCollection

stevearas — Tue, 30 Oct 2012 19:54:36 GMT

Instead of having a list of objects, I have a container object (Activities) that has a ItemCollection based on IEnumerable<Object> that holds the (Activity) objects. I instantiate "Activities" like CurrentActivities, PossibleActivites. I try to replicate/modify the example SaveAndLoadListOfPocos like this

  public async Task SaveRealActivities()
        {
           var osh = new ObjectStorageHelper>(StorageType.Local);
            await osh.SaveAsync(_realActiv.Collection);

        }

I get a build error. It certainly doesn't like the way I'm coding it.

Hi,

Thanks for the comment, and positive feedback.

I don't currently have any plans to make this available as a Nuget package. Wouldn't even know how to.

Sounds like a good idea though and its something I might look into one day - right now any work on this is on the backburner due to some other projects.

regards

Jamie

Great work by the way. I was 50% done creating a generic utility such as this, then found yours and saved some time.

New Post: Calling from Javascript

Hi Swellenator,

I wish I had a good answer for you but unfortunately I haven't done work on any of the WinJS stuff. I'm not a JS guy I'm afraid (actually I'm not really a .Net guy either but whatever ... :) )

If you get an answer I'd appreciate you posting some guidance up here in case anyone else experiences the same.,

regards

Jamie

New Post: Calling from Javascript

Swellenator — Wed, 27 Jun 2012 12:11:16 GMT

HI,

I am trying to use your code in a WinRT javascript project. I'm not sure how to do it!

� � var storageHelper = new NotificationsExtensions.ObjectStorageHelper(NotificationsExtensions.ObjectStorageHelper.StorageType.Roaming);

Throws Throws a '0x800a01bd - JavaScript runtime error: Object doesn't support this action'.

I set the name spaces etc as

namespace NotificationsExtensions.ObjectStorageHelper
{
    public enum StorageType
    {
        Roaming, Local, Temporary
    }

    internal sealed class ObjectStorageHelper<T>
    {

etc. the StorageType enum is exposed from the JS code but no other methods are? Any Ideas? I can't seem to make the class public as it complains about the generic type.
