  • Passing a complex object to a page while navigating in a WP7 Silverlight application

    - by Andreas Grech
    I have been using the NavigationService's Navigate method to navigate to other pages in my WP7 Silverlight app: NavigationService.Navigate(new Uri("/Somepage.xaml?val=dreas", UriKind.Relative)); From Somepage.xaml, I then retrieve the query string parameters as follows: string val; NavigationContext.QueryString.TryGetValue("val", out val); I now need a way to pass a complex object using a similar manner. How can I do this without having to serialize the object every time I need to pass it to a new page?

  • Javascript: Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?

  • [Embedded Python] Invoking a method on an object

    - by jmucchiello
    Given a PyObject* pointing to a python object, how do I invoke one of the object methods? The documentation never gives an example of this: PyObject* obj = .... PyObject* args = Py_BuildValue("(s)", "An arg"); PyObject* method = PyWHATGOESHERE(obj, "foo"); PyObject* ret = PyWHATGOESHERE(obj, method, args); if (!ret) { // check error... } This would be the equivalent of >>> ret = obj.foo("An arg")

  • Django admin - remove field if editing an object

    - by John McCollum
    I have a model which is accessible through the Django admin area, something like the following: # model class Foo(models.Model): field_a = models.CharField(max_length=100) field_b = models.CharField(max_length=100) # admin.py class FooAdmin(admin.ModelAdmin): pass Let's say that I want to show field_a and field_b if the user is adding an object, but only field_a if the user is editing an object. Is there a simple way to do this, perhaps using the fields attribute? If if comes to it, I could hack a JavaScript solution, but it doesn't feel right to do that at all!

  • Replace Entity Framework object

    - by majkinetor
    In MVC app, I am having this big object that is used in classic view/edit/create pattern. When user edits the object I save it as: public bool SetMyObject(MyObject newObject) { MyObject current = GetObjectById(newObject.Id); current.Prop1 = newObject.Prop1 ... current.PropN = newObject.PropN db.SaveChanges(); } MyObject is pretty big so I am wondering is there any better way to do this, not involving per-property assignments. For instance something along the lines db.MyObject.UpdateObject(current, tnew). Ty.

  • Copy values from one object to another.

    - by BrokeMyLegBiking
    Anyone have a suggestion for a good utility class that maps values from one object to another? I want a utility class that uses reflection and takes two objects and copies values from the 1st object to the second if there is a public property with the same name. I have two entities that are generated from a web service proxy, so I can't change the parent class or impliment an interface or anything like that. But I know that the two objects have the same public properties.

  • Method-Object pairs in Java

    - by John Manak
    I'd like to create a list of method-object pairs. Each method is a function returning a boolean. Then: foreach(pair) { if method evaluates to true { do something with the object } } One way of modelling this that I can think of is to have a class Constraint with a method isValid() and for each constraint produce an anonymous class (overriding the isValid() method). I feel like there could be a nicer way. Can you think of any?

  • Creating object in database without showing view to user

    - by samuil
    I have controller with action new, and I want it to create ActiveRecord::Base descendant object, and write it into database (without showing it to user). def new active_order = current_user.orders.find {|o| o.status > 0 } active_order = Order.new if active_order.nil? (...) end Order.new creates local object, but my question is -- how to make Rails to fill it with default values and write to database?

    - by taskforce145
    I need to use a function on a vector that does not take a ts object. I'm trying to convert it to a plain old vector but I just can't seem to figure it out. I googled around but mostly people are trying to convert data types into ts object. I want to go the other way. Any help would be appreciated.

  • instantiate object with reflection using constructor arguments

    - by justin
    I'm trying to figure out how to instantiate a case class object with reflection. Is there any support for this? The closest I've come is looking at scala.reflect.Invocation, but this seems more for executing methods that are a part of an object. case class MyClass(id:Long, name:String) def instantiate[T](className:String)(args:Any*) : T = { //your code here } Is close to the API I'm looking for. Any help would be appreciated.

    I want to copy a record with all his relations. I'm trying with: $o = Doctrine::getTable('Table')->Find(x); $copy = $object->copy(); $relations = $o->getRelations(); foreach ($relations as $name => $relation) { $copy->$relation = $object->$relation->copy(); } $copy->save(); This code doesn't works, but I think it's on the way.

  • Convert any object to pretty HTML in java

    - by ripper234
    How can I convert a given object (in a generic way with reflection) to pretty printable HTML? What ready made library do you recommend that does this? I need support for simple nested objects (as long as they don't create loops in the object graph). I tried to convert it to JSON, but DefaultPrettyPrinter is not HTML friendly.

    Hi, Can we use foreach loop for Iqueryable object? I'd like to do something as follow: query = Iqueryable<Myclass> = objDataContext.Myclass; // objDataContext is an object of LINQ datacontext class int[] arr1 = new int[] { 3, 4, 5 }; foreach (int i in arr1) { query = query.Where(q => (q.f_id1 == i || q.f_id2 == i || q.f_id3 == i)); } It gives me wrong output as each time value if i is changed.
