  • Serialze an Object to a String

    - by Vaccano
    I have the following method to save an Object to a file: // Save an object out to the disk public static void SerializeObject<T>(this T toSerialize, String filename) { XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType()); TextWriter textWriter = new StreamWriter(filename); xmlSerializer.Serialize(textWriter, toSerialize); textWriter.Close(); } I confess I did not write it (I only converted it to a extension method that took a type parameter). Now I need it to give the xml back to me as a string (rather than save it to a file). I am looking into it, but I have not figured it out yet. I thought this might be really easy for someone familiar with these objects. If not I will figure it out eventually.

  • looping through object properties in actionscript

    - by asawilliams
    I have a dynamic class that I have created public dynamic class SiteZoneFileUploadVO { public var destination:String = "sitezone"; public var siteZoneId:uint; public var fileType:String; public var fileContents:String; public function SiteZoneFileUploadVO() { } } when I try to iterate over this object's properties it only iterates the dynamically added properties. parameters.dynVar= "value"; for(var name:String in parameters) { trace(name); } Even though the object has all the properties equal to a value (ive checked this in the debugger) the only property that will be traced is dynVar. How can I iterate over all the properties and not just the dynamically added ones?

  • how to create a custom settings view / make cell label editable

    - by Lex
    Hi everyone, I need to create a custom settings view used within the app. The app is a mockup so it actually does have one already, it uses a UITableViewCellStyleValue1, but nothing is editable. So essentially what I would like to have is the same thing but with editable detailTextLabel (the label on the right hand side), what's the best way to do this?

  • Custom QAction/QMenu for mouse button detection

    - by voodoogiant
    I'm trying to create a popup menu, where I can detect the mouse button that was pressed for a given item. I've created a custom QAction already to build my QMenu, but the triggered signal when the menu item is pressed doesn't provide a QMouseEvent for me to query the button pressed. Also, I'm setting the a status tip for each QAction, which appears in the status bar when I mouse over it, but it stays even after I close the QMenu. Is this normal behavior?

  • Force result for empty() test on an object

    - by hsz
    Hello ! Simple class for example: class Foo { protected $_bar; public function setBar( $value ) { $this->_bar = $value; } } And here is the question: $obj = new Foo(); var_dump( empty( $obj ) ); // true $obj->setBar( 'foobar' ); var_dump( empty( $obj ) ); // false Is it possible to change class's behaviour with testing it with empty() function so it will returns true when object is not filled with data ? I know about magic function __isset( $name ) but it is called only when we test specific field like: empty( $obj->someField ); but not when test whole object.

  • restricting the property type of a custom attribute

    - by Guy
    Does anyone knows if it is possible to define/declare on your own custom attribute a restriction to the field type it may apply on? There are a flags that do restrict the usage of the attribute: [AttributeUsage( AttributeTargets.Property, AllowMultiple = false)] Im looking for something like: UseOnlyOnType = typeof(string) Any ideas?

  • Need Help With ASP.NET Custom Route

    - by Jason
    I need to create a custom route to list all the rooms in a given building. So, I want the url to look something like this: /Building/1000/Room Which would list all the rooms in Building 1000. Is this the correct mapping for the route (to call the IndexByBuilding method in RoomController)? routes.MapRoute( "RoomsByBuilding", "Building/{id}/Room", new { controller = "Room", action = "IndexByBuilding", id = "" } );

  • Saving a modified object from ASP.NET MVC View Using Entity-Franework 4

    - by Dani
    I retrieve an object graph from DB using EF4. The context is closed as soon as the data retrieve and the data passes to the controller, and then to the view. in the view the data is modified, and then the controller gets it back. From the controller I run Repository.Update(MyEmp); and in my repository the code goes: using (var context = new mydb()) { if (myEmp.ID != 0) // Checking if it's modified or new { context.Emp.Attach(MyEmp); int result = context.SaveChanges(); return myEmp.ID; } } The problem - once attached, the object entityState goes to unchanged, and not modified, and of course - nothing is saved to the database. What am I doing wrong ?

  • Return an opaque object to the caller without violating type-safety

    - by JS Bangs
    I have a method which should return a snapshot of the current state, and another method which restores that state. public class MachineModel { public Snapshot CurrentSnapshot { get; } public void RestoreSnapshot (Snapshot saved) { /* etc */ }; } The state Snapshot class should be completely opaque to the caller--no visible methods or properties--but its properties have to be visible within the MachineModel class. I could obviously do this by downcasting, i.e. have CurrentSnapshot return an object, and have RestoreSnapshot accept an object argument which it casts back to a Snapshot. But forced casting like that makes me feel dirty. What's the best alternate design that allows me to be both type-safe and opaque?

  • Can I bypass an intermediate object in hibernate

    - by Jherico
    I have top level entities TRACK, MEDIA_GROUP and MEDIA, each with an integer primary key. I also have a join table from TRACK to MEDIA_GROUP which is 1:1 and MEDIA has a FK column into MEDIA_GROUP. I'm trying to find a way in hibernate to map a collection of Media directly into the Track object, bypassing the creation of a MediaGroup object. Basically I want to turn this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA_GROUP <-> MEDIA into this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA But the join column between MEDIA_TRACK_MAP and MEDIA isn't the primary key of MEDIA.

  • C#, Using Custom Generic Collection faster with objects than List

    - by Kaminari
    Hello, I'm using for now List< to iterate through some object collection and find matching element, The problem is that object has only 2 significant values Name and Link (strings) but has some other values wich I dont want to compare. I'm thinkig about using something like HashSet (wich is exactly what I'm searching for - fast) from .NET 3.5 but target framework has to be 2.0. There is something called Power Collections here: http://powercollections.codeplex.com/ But maybe there is other way? If not, can you suggest me a suitable custom collection?

  • finding last loop through a jQuery object

    - by DA
    Sample jquery. Assume $cog is a cached selector of multiple items. $cog.fadeOut('slow',function(){ alert('hey'); }) In that example, of $cog is a jQuery object of 4 DOM elements, the above will fade each element out one by one, and trigger an alert each time on the callback (4 alerts). I'd like to only call the alert when all 4 elements are done with their fadeOut function. This: $cog.fadeOut('slow',function(){ }) alert('hey'); when run, will show an alert, then the $cog elements disappear (I'm guessing due to timing issues with the fadeOut animation) Is there a way when calling a function against multiple DOM objects in a jQuery object to know when it's done with the last item?

Any help or pointers in the right direction would be much appreciated!
