Using Zend_Amf it's possible to serialize php objects to/from Adobe AMF format.
Is there an equivalent library for serializing/unserializing C# objects to/from AMF?
I'm working in Mono 2.4.
Hi, I've got collection of geo objects in database:
There are four Tables:
Countries
Regions
Provinces
Cities
Cities has inter alia ProvinceCode
Provinces has inter alia regionCode
Regions has inter alia CountryCode
And there is fifth Table: Descriptions
ObjectCode
ObjectType(country, region, province, city)
Description.
How to get from Descriptions table, all descriptions from objects which are in the definite country ??
Hi, I am looking for an algorithm that would be useful for determining x y coordinates for a number objects to display on screen. Each object can be related to another object and there can be any number of relationships and there can be any number of these objects.
There is no restriction on the overall size of area on which to display these object.
I am writing this in php and would be looking to store the coordinates in an array.
Hi,
When using inline formsets, how does one do paging? I'm using django 1.1.
The situation I'm in, is that the user needs to be able to edit the related objects quickly and easily (which is why I think I should be using an inline formset). However, there can be a more than a hundred objects to edit, which makes a pretty large formset, so paging would make sense.
Is there a better way to be doing this?
Thanks

Does anyone know of a widget that displays 2 select boxes. One shows a list of all object in a model and the other shows the objects which have been selected. The user can then select an object from the first list, click an button which moves it to the 'selected' list. Then when the form is saved the objects in the selected list are saved in the manytomany field.
Thanks
I was trying to merge my master branch with another one called pull-stage, but Git throws me this error:
error: inflate: data stream error (invalid distance too far back)
error: corrupt loose object '5a63450f4a0b72abbc1221ccb7d9f9bfef333250'
fatal: loose object 5a63450f4a0b72abbc1221ccb7d9f9bfef333250 (stored in .git/objects/5a/63450f4a0b72abbc1221ccb7d9f9bfef333250) is corrupt
How can I solve this issue?

Hi,
I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-(
The model is something like:
@SuppressWarnings("serial")
@Entity
public class Thing implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
private int id;
private String name;
@OneToMany(cascade=CascadeType.ALL)
@PrivateOwned
private List<Property> properties = new ArrayList<Property>();
...
// getter and setter following here
}
public class Property implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
private int id;
@OneToOne
private Item item;
private String value;
...
// getter and setter following here
}
public class Item implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
private int id;
private String name;
....
// getter and setter following here
}
// Code end
In the table view the y-axis is more or less created with the query
Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC");
using the "name" attribute from the Thing objects as label.
In the table view the x-axis is more or less created with the query
Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC");
using the "name" attribute from the Item objects as label.
Each cell has the value
Things.getProperties().get[x].getValue()
Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis.
And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet.
Thank you for your help and your ideas to solve this riddle.
Hi, i am building a C project with Xcode and when ever i build it it gives me this error:
ld: duplicate symbol _detectLinux in /Users/markszymanski/Desktop/Programming/C/iTermOS/build/iTermOS.build/Debug/iTermOS.build/Objects-normal/i386/linuxDetect.o and /Users/markszymanski/Desktop/Programming/C/iTermOS/build/iTermOS.build/Debug/iTermOS.build/Objects-normal/i386/iTermOS.o
Thanks!
One particular user is getting an exception when connecting an application I created to a third party app using COM. The connection fails with the following error:
Source: mscorlib
Message: Exception from HRESULT: 0x80040202
This software works fine for other users.
Any ideas what could be going on?
The error occurs just before the app adds some event handlers to some of the COM objects from the third party app. It is able to successfully instantiate the objects, though.
Hi,
In the application I am developing, I would like to send messages in the form of JSON objects to a Django Server and parse the JSON response from the server and populate a custom listview.
From the little JSON knowledge I have, I thought this format for the response from server
{
"post": {
"username": "someusername",
"message": "this is a sweet message",
"image": "http://localhost/someimage.jpg",
"time": "present time"
},
}
How much knowledge of JSON should I have to accomplish this purpose? Also it would be great if someone could provide me links of some tutorials for sending and parsing JSON Objects.
My app spawns a secondary thread for some core data store maintenance. In the secondary thread, I set up a context which I then pass to other methods e.g. [self editEntriesInContext:context]. However, this causes objects fetched from the context to become invalidated in editEntries...
Why does this occur? I thought the only requirements were for the secondary thread to have its own context and managed objects, which I adhere to.
(Note: The context is properly retained)
Is it possible to mimic IQueryable with NHibernate?
I was looking at Nhibernate docs and for what i could tell, it always returns a List of objects, that have it's attributes indexed by a integer. Ok, perfect, that works.
But is there a way to retrieve objects like LINQ? With something like IQueryable?
Thanks
So I know that I can communicate between those two using JSON, but I also know that I would have to manually recreate all Django objects in JS.
Do you know of any tool or library that could help me do that? Or maybe even a better way of achieving the same goal?
I only found these two: http://palantar.blogspot.com/2006/06/agad-tutorial-ish-sort-of-post.html http://stackoverflow.com/questions/990319/django-gwt-or-jquery
But then I still would have to manually mirror my objects, which would violate DRY.
Hi I am trying to convert some objects to json using the JavaScriptSerializer() class.
Some of the objects include xml.
Is there a way to stop it converting < to \u003c ?
Hello guys,
What I want to do is simple. I have a generic list of objects. Let's say the object class contains a property named Height. What I want to do is bind a textbox's text in the UI with this list and when i change the value in the textbox then all objects in the list update their height value. I am new in WPF, I have studied the MVVM pattern, I can do simple data binding but i can't figure out how to do this :'( Thanks!
I have an object which is a composite of several other objects. When i use the getObjectSize() method in the Instrumentation package, does it include the size of the composite objects also?
Getters and Setters are bad
Briefly reading over the above article I find that getters and setters are bad OO design and should be avoided as they go against Encapsulation and Data Hiding. As this is the case how can it be avoided when creating objects and how can one model objects to take this into account.
In cases where a getter or setter is required what other alternatives can be used?
Thanks.
I'm walking into a project with 500+ classes, and am wondering if anyone has had good experiences with automated modeling tools that can import from ASP.Net /C#?
It would be a bonus if I could get an automated model based on all the objects called to completely load a single ASP.Net page, with relationships indicating which objects are calling out to which other ones, etc.
Thanks for sharing your thoughts or recomendations.
I have an NSTreeController (supplying content to an NSOutlineView). I'd like the top-level objects to be of one class, and all other objects (so, children at any level) to be of another. What's the best way to go about this?
I'll need to somehow change the behavior of at least add, addChild, insert, and insertChild, I suppose. I was hoping, though, to find a simple way to account for this in only one location, rather than changing four separate methods.
Is there a nice way to do this in Objective-C, or do I have to write my own tedious logic?
I'm creating and destroying a little of little state objects per frame in an iPhone game. It would be nice if I could just reuse objects from a pool.
This question is a follow on from this one...
I am binding to a heterogeneous collection of objects, not all objects have the same set of properties. I am doing this in a datagrid. I would like to gray out the cell if the binding fails. Is there a way to apply a trigger if a binding fails?
Im currently creating a tile-based game for android. Using java via dalvik JVM. im fretting over a decision to represent objects in a particular map. should i use an id based map (2 dimensional integer array) and place game logic in a separate function in the game engine, or create an object array (2 dimensional array of game objects) and store game logic within the class methods. i am thinking about the cost of object creation and garbage collection vs extensibility.
I have tested my iphone app using XCode and instrument. I am watching the memory allocation tables, its showing me that every things is increasing i.e Bytes, Live Bytes and so on.
What does it means? Am i not deallocating the objects?
Can i find which objects are not deallocating using instruments?

I have a few List< objects that hold many objects of one specific type. My goal is to combine these List<'s into one List<. Of course, I could just loop through each List's contents and add them into one final List, but is there a more efficient way?
