  • JSON parsing using JSON.net

    - by vbNewbie
    I am accessing the facebook api and using the json.net library (newtonsoft.json.net) I declare a Jobject to parse the content and look for the specific elements and get their values. Everything works fine for the first few but then I get this unexplained nullexception error " (Object reference not set to an instance of an object) Now I took a look at the declaration but cannot see how to change it. Any help appreciated: Dim jobj as JObject = JObject.Parse(responseData) Dim message as string = string.empty message = jobj("message").tostring The error occurs at the last line above.

  • Rails - Accessing model class methods from within ActiveRecord model

    - by aaronrussell
    I have a simple standalone model that doesn't inherit from ActiveRecord or anything else, called SmsSender. As the name suggests, it delivers text messages to an SMS gateway. I also have an ActiveRecord model called SmsMessage which has an instance method called deliver: def deliver SmsSender.deliver_message(self) self.update_attributes :status => "Sent" end The above is returning uninitialized constant SmsSender. I'm sure this is dead simple, but how can I access the SmsSender class from within my model?

  • Exploded (unpacked) EAR vs. Packaged EAR file?

    - by Adam
    In my office we use exploded EAR's (and inside them exploded WAR directories) for our test environments, and then a packaged one for production. I've yet to find a good explanation of the reason behind this though. I understand it's easier from a deployment perspective to push out a single file during builds, but it prevents us from doing things like property file changes without doing complete rebuilds (we could skip the compiles, but our environment currently binds the compile and jar processes together). What are the major advantages / disadvantages between these two configurations?

  • How are DynamicResources built?

    - by miguel
    Are dynamic resources truly dynamic? If I define a DynamicResource, I realise that an expression is created (where?) that is not translated into a resource until runtime, however, What I do not understans is whether this dynamicresouce, once built, is now "Static" For instance, if I create a context menu via a dynamicresource, are the menuitems which are created at runtime on access then static, even if they are bound?

  • Is it possible to run a Java program inside a Flex application?

    - by Joshua
    I would like to be able to incorporate a simple game, written in Java as a component within a Flex Application. Am I crazy? Flex can display HTML, and SWF, it can also call JavaScript - but can I incorporate an applet somehow? I do NOT mean kludging it in as a sister component within a browser, but actually within the flex application itself, so that it could also run under Adobe Air, for instance.

    - by Zach
    I have 2 models: class A(Model): #Some Fields objects = ClassAManager() class B(A): #Some B-specific fields I would expect B.objects to give me access to an instance of ClassAManager, but this is not the case.... >>> A.objects <app.managers.ClassAManager object at 0x103f8f290> >>> B.objects <django.db.models.manager.Manager object at 0x103f94790> Why doesn't B inherit the objects attribute from A?

  • A Question on Encapsulation.

    - by Bragaadeesh
    Hi, I know that encapsulation is binding the members and its behavior in one single entity. And it has made me think that the members have to be private. Does this mean if a class having public members is not following 100% Encapsulation rule? Thanks

  • Searching via Tags in SharePoint 2010

    - by Ben
    Is it possible to search on Tags within SharePoint 2010? I know you can refine your search based on Tag (Search for a keyword, then filter by Tags) and you can use the "Tag Cloud", but that doesnt let you search by more then one Tag. How would I for instance, search for some documents that I have tagged as "Technical" and "Internal", and return all items tagged with both of those tags?

What would be the most efficient way to accomplish this?
