  • How can I get the width/height of a loaded swf's stage in AS2?

    - by loopj
    I'm using MovieClipLoader to load an external as2 swf file into my as2 flash project, and I'm having trouble getting the original stage size of the loaded swf. When I run the following code: var popup:MovieClip = _root.createEmptyMovieClip("popup", 1); var loader:MovieClipLoader = new MovieClipLoader(); var loadHandler:Object = new Object(); loader.addListener(loadHandler); loader.loadClip(url, popup); loadHandler.onLoadInit = function(mc:MovieClip) { trace(mc._width + ", " + mc._height); } I get strange width/height values (mc._width=601.95, mc._height=261.15) when what I actually want is the stage size of the loaded swf file, which in this case I know to be 300px x 250px. Any suggestions appreciated! Thanks

  • help designing a method, should I use out or ref or return the type?

    - by Blankman
    I have a method that I will use in the following contexts: 1. User user = null; if(...) { user = defaultUser; SetUser(a,b,user); } else { SetUser(a,b,user); } SaveUser(user); So some cases are where user may be null, while in other cases it will already be initialized. How should I design the SetUser method? I currently have it like so, but this causes an error when user is null. public void SetUser(object a, object b, User user) { if(user == null) user = new User(); user.Security = a.security; user.Blah = b.type; }

  • Delegation, is this just opinionated or is there a common pattern?

    - by user1446714
    If I have a java class containing substantial code and I wish to add extra features, am I right in thinking the delegate class would have the additional features added as methods. Then my original class would create the delegate object and just call the extra functionality via the delegate instance? I am being told by somebody else that my original class should become the delegate and that the class containing the new functionality should contain an instance of the original class, to use as a delegate? This seemed a little backward to me, because there would be far more delegate calls because most of the code is now in the delegate.... I was always under the impression the delegate object would contain the additional new behaviour and an instance of it would be in the original class to inboke the new behaviour from?

  • How do you override operator == when using interfaces instead of actual types?

    - by RickL
    I have some code like this: How should I implement the operator == so that it will be called when the variables are of interface IMyClass? public class MyClass : IMyClass { public static bool operator ==(MyClass a, MyClass b) { if (ReferenceEquals(a, b)) return true; if ((Object)a == null || (Object)b == null) return false; return false; } public static bool operator !=(MyClass a, MyClass b) { return !(a == b); } } class Program { static void Main(string[] args) { IMyClass m1 = new MyClass(); IMyClass m2 = new MyClass(); MyClass m3 = new MyClass(); MyClass m4 = new MyClass(); Console.WriteLine(m1 == m2); // does not go into custom == function. why not? Console.WriteLine(m3 == m4); // DOES go into custom == function } }

  • Empty dict-like collection problem in SQLAlchemy

    - by maksymko
    I have a mapping in SQLAlchemy that looks like this: t_property_value = sa.Table('property_value', MetaData, autoload = True, autoload_with = engine) orm.mapper(PropertyValue, t_property_value) t_estate = sa.Table('estate', MetaData, autoload = True, autoload_with = engine) orm.mapper(Estate, t_estate, properties = dict( property_hash = orm.relation(PropertyValue, collection_class = column_mapped_collection(t_property_value.c.property_id)) )) Now, everything seems to be fine, when I load the Estate object and it has some relations to PropertyValue objects. However, when it does not, then property_hash attribute is None, instead of being something dict-like, so I can not add new relations like this: estate.property_hash[prop_id] = PropertyValue(...) because I get the "'NoneType' object does not support item assignment" error. So, is there any way to force SQLAlchemy to create proper empty collection?

  • Finding the attributes on the properties of an instance of a class

    - by Dan
    Given an instance of a class I want to set properties on attributes at runtime. So I tried this, but as far as I can tell this finds the attributes on the class not the instance, so any changes I make to the attribute properties have no effect. var properties = myObject.GetType().GetProperties(); foreach (object prop in properties) { var attribute =prop.GetCustomAttributes(typeof(MyAttribute), true)[0]; //attribute.MyProp do some stuff } If I try using type descriptor like below, there is no way of getting to the attributes on the properties. var myObject= (MyClass) object; PropertyDescriptorCollection props = TypeDescriptor.GetProperties(myObject); //There is no props[0].GetCustomAttributes(

  • Ruby (and Rails) nested module syntax

    - by brad
    I'm wondering what the difference is between the following two modules # First Example module Parent module Child end end and # Second Example module Parent::Child end Using the 2nd method, it appears as though the Parent module must be previously defined, otherwise I get an 'uninitialized constant' error Given this, what is the preferred way of defining modules such as this and then adding nested children with regards to syntax and file structure (ie. folders etc). Reference to a Rails way would be greatly appreciated. Are these two examples for all intents and purposes equivalent?

  • How do I specify a null relation in SQLAlchemy?

    - by Jesse
    Not sure what the correct title for this question should be. I have the following schema: Matters have a one-many relationship to WorkItems. WorkItems have a one-one (or one-zero) relationship to LineItems. I am trying to create the following relation between Matters and WorkItems Matter.unbilled_work_items = orm.relation(WorkItem, primaryjoin = (Matter.id == WorkItem.matter_id) and (WorkItem.line_item_id == None), foreign_keys = [WorkItem.matter_id, WorkItem.line_item_id], viewonly=True ) This throws: AttributeError: '_Null' object has no attribute 'table' That seems to be saying that the second clause in the primaryjoin returns an object of type _Null, but it seems to be expecting something with a "table" attribute. This seems like it should be pretty straightforward to me, am I missing something obvious?

  • Using methods from the "outer" class in inner classes

    - by devoured elysium
    When defining nested classes, is it possible to access the "outer" class' methods? I know it's possible to access its attributes, but I can't seem to find a way to use its methods. addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { if (e.getClickCount() == 2 && //<-- Here I'd like to } // reference a method }); //from the class where //addMouseListener() is defined! Thanks

  • OpenLayers: Get resolution of map in a given projection (4326)

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom. This should be relatively easy to do using the getResolution and calculateBounds methods on the Map object. calculateBounds returns a Bounds object that then can be transformed between the map projection and display projection. How do I transform the resolution into my desired projection (4326 in this case)?

  • WCF net.tcp server disconnects - how to handle properly on client side?

    - by RoastedBattleSquirrel
    I'm stuck with a bit of an annoying problem right now. I've got a Silverlight 4 application (which runs OOB by default). It uses WCF with net.tcp as means of communicating with the server. The client uses a central instance of the wcf client proxy. As long as everything keeps running on the server side, everything's fine. If i kill the server in the middle of everything, i drown in an avalanche of exceptions on the client side (connection lost, channel faulted etc etc). Now i'm looking for a way to handle this in a clean and centralized way (if centralized is possible). The SL app has one central client object sitting in App.cs (public static MyClient Client { get;set;}), which gets initialized on application start. Any idea how to properly handle any connectivity problems on the client object?

  • AspectJ join point with simple types

    - by Jon
    Hi! Are there defined join points in arithmetics that I can catch? Something like: int a = 4; int b = 2; int c = a + b; Can I make a pointcut that catches any one of those lines? And what context will I be able to get? I would like to add a before() to all int/float/double manipulation done in a particular method on a class, is that possible. I see in the AspectJ docs that there are defined join points for object initialization and method calls. Is declaring an int an object initialization and does the + operator count as a method call? Thanks!

  • ASP ListView: How do I access the data that is databound to the rows?

    - by Robert
    I want to access the data that was databound to my list view when handling list view events such as: protected void List_ItemDataBound(object sender, ListViewItemEventArgs e) or protected void List_ItemCommand(object sender, ListViewCommandEventArgs e) Inside the events, I can not access the data via somthing like Eval("ID") Currently we are using a very hacky solution: string id = e.Item.FindControl("lblID").Text; Where lblID is a hidden control that is populated with data in the aspx file using: <asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' /> My eyes bleed when I look at this, Is there a better way?

  • Weird exception with delayed_job

    - by Tam
    Trying to queue a job with delayed_job as follows: Delayed::Job.enqueue(BackgroundProcess.new(current_user, object)) current_user and object are not nil when I print them out.

  • JSObject-like stuff in ActionScript 3?

    - by johncch
    I would like to ask if there is a liveconnect equivalent for ActionScript 3. I understand that there is the ExternalInterface class inside AS3 but it only supports calling a method by name. The really cool thing about Java and LiveConnect is that you can do something like function jsFunc(name) = { this.name = name; this.talk = function(){ alert('hello world my name is ' + this.name); } } javaapplet.function(new jsFunc("bob")); The above approaches pseudo code since I never tested it but I've seen it in action. In AS3, while I am able to pass in an instance of JavaScript "object" into AS, it is often converted into an ActionScript Object instance which does away with all the functions as far as I'm aware. I saw an implementation of JSInterface but I don't think it does specifically that. Is there any way to make OO like javascript work with ActionScript 3?

  • How do you add objects to a javascript namespace?

    var Test = (function() { return { useSub: function () { this.Sub.sayHi(); }, init: function () { $(document).ready(this.useSub); } }; })(); Test.Sub = (function () { return { sayHi: function () { alert('hi'); } }; })(); Test.useSub(); // works Test.init(); // explodes Above I am trying to create a Test namespace and add an object Sub to it. I was doing fine until I tried using the object in jQuery. The error is "Uncaught TypeError: Cannot call method 'sayHi' of undefined". If there is a better way to do this, I am open to it.

  • A better way to do XML in Java

    - by jboyd
    There are a lot of questions that ask the best XML parser, I am more interested in what is the XML parser that is the most like Groovy for Java? I want: SomeApiDefinedObject o = parseXml( xml ); for( SomeApiDefinedObject it : o.getChildren() ) { System.out.println( it.getAttributes() ); } The most important things are that I don't want to create an object for every type of filed, I'd rather just deal with them all as strings, and that building the XML doesn't require any converters or anything, just a simple object that is already defined If you have used the Groovy XML parser, you will know what I'm talking about Alternatively, would it be better for me to just use Groovy from Java?

  • Can I make PDOStatement->fetchObject not use non-member variables?

    - by threendib
    Lets say I have a class like this: Class User { var $id var $name; } And I run a query using PDO in php like so: $stm = $db->prepare('select * from users where id = :id'); $r = $stm->execute(array(':id' => $id)); $user = $r->fetchObject('User'); If I vardump my user object it has all kinds of other fields in it that I have not defined in the User class. Obviously I could make my query specific so that it only gives me back the fields I need/want. But if I don't want to do that is there any way to make this work the way I want it to? I like the idea of fetchObject, because it's one line of code to create this object and set member variables for me. I just don't want it to set variables I haven't defined in my class.

  • C++: Accessing std::map keys and values

    - by Jay
    How do you access an std::vector of the keys or values of an std::map? Thanks. Edit: I would like to access the actual elements, not just copies of their contents. essentially I want a reference, not a copy. This is essentially what I am wanting to do: std::map<std::string, GLuint> textures_map; // fill map glGenTextures( textures_map.size(), &textures_map.access_values_somehow[0] );
