• Finalizing a COM object

  - by Neverrav

  I'm trying to implement a singleton class, that holds a com object inside it. Class implements IDisposable interface, but when I try to implement a finalization method, I get an exception of access to com object from another thread. This happens because clr uses a different thread when finalizes objects. Is there any way to implement such a thing or maybe I just doing something wrong?

• Java constructor with large arguments or Java bean getter/setter approach

  - by deelo55

  Hi, I can't decide which approach is better for creating objects with a large number of fields (10+) (all mandatory) the constructor approach of the getter/setter. Constructor at least you enforce that all the fields are set. Java Beans easier to see which variables are being set instead of a huge list. The builder pattern DOES NOT seem suitable here as all the fields are mandatory and the builder requires you put all mandatory parameters in the builder constructor. Thanks, D

• How do I get row count using the NHibernate QueryOver api?

  - by Jim Geurts

  I'm using the QueryOver api that is part of NHibernate 3.x. I would like to get a row count, but the method I'm using returns all objects and then gets the count of the collection. Is there a way to just return an integer/long value of the number of rows? I'm currently using: _session.QueryOver<MyObject>().Future().Count()

• If I replace an image in a PictureBox control, should I dispose the original image first? .Net Winfo

  - by Jules

  Following on from my question here http://stackoverflow.com/questions/2548664/long-overdue-for-me-question-about-disposing-managed-objects-in-net-vb-net , If I replace an image in a picture box, should I dispose the original image first? Or, what about this situation: Dim bm As New Bitmap(32,32) bm = New Bitmap(32,32) bm = New Bitmap(32,32) bm = New Bitmap(32,32) Does bm need only to be disposed at the end, or should it be disposed before each re-creation?

• Dynamically change my schema

  - by Kirk

  I am wondering if there is a way to change the schema that I am working in while inside Management Studio. For instance I may have a default schema of dbo. But there are times I may want to query objects in say the accounting schema. It would be nice if I could issue a command and make it so I no longer must include the accounting before tables and views. But the next time I go in, I will be back to default of dbo.

  I'm reading a book about DI that always talks about DI frameworks "instantiating an object graph". Why say it this way rather than "instantiating objects"?

• Interface in a dynamic language?

  - by Bryan

  Interface (or an abstract class with all the methods abstract) is a powerful weapon in a static language. It allows different derived types to be used in a uniformed way. However, in a dynamic language, all objects can be used in a uniformed way as long as they define certain methods. Does interface exist in dynamic languages? It seems unnecessary to me.

• Form.GetChildsAtPoint

  - by serhio

  I would like to obtain the list of controls under a given point. There is a method on System.Windows.Form to obtain a control under a point(GetChildAtPoint) but not point(GetChildsAtPoint). Is there something similar for the list of controls (if borders intersect one other): I need this because I select the objects when user clicks on the panel(I use Microsoft.VisualBasic.PowerPacks.RectangleShape as label bellow). In case if labels are superposed, user should be asked what object to select.

• C# OOP File Structure?

  - by Soo

  Hey SO, I just started programming with objects recently and am trying to learn good habits early on. The way I plan to structure my application is to have two files: 1: Program.cs - This file will contain the main logic for the application 2: Class.cs - This file will contain all of the class definitions Pretty simple. What I'm wondering if I should have any more files for ... well, you tell me. Any help would be appreciated.

  Hi, I have inherited a class, say CstateUI from Control class. I am creating an object of CstateUI and setting up the margin of the object.

Can you please tell me what possibly might be going wrong? Thanks in advance!

• What is Object Decomposition?

  - by Mustafa

  Hi everyone, I was trying to understand what object decomposition means and read a lot of stuff on internet but every resource talks in terms of lots of keywords that i couldn't understand. So these resources expect you to know a few terms. I need something that lists the basics of decomposition from scratch. Is it anything more than breaking the design into objects? If no, any description will be appreciated. Thanks in advance

• Question about design (inheritance, polymorphism)

  - by Dan

  Hi, I have a question about a problem I'm struggling with. Hope you can bear with me. Imagine I have an Object class representing the base class of a hierarchy of physical objects. Later I inherit from it to create an Object1D, Object2D and Object3D classes. Each of these derived classes will have some specific methods and attributes. For example, the 3d object might have functionality to download a 3d model to be used by a renderer. So I'd have something like this: class Object {}; class Object1D : public Object { Point mPos; }; class Object2D : public Object { ... }; class Object3D : public Object { Model mModel; }; Now I'd have a separate class called Renderer, which simply takes an Object as argument and well, renders it :-) In a similar way, I'd like to support different kinds of renderers. For instance, I could have a default one that every object could rely on, and then provide other specific renderers for some kind of objects: class Renderer {}; // Default one class Renderer3D : public Renderer {}; And here comes my problem. A renderer class needs to get an Object as an argument, for example in the constructor in order to retrieve whatever data it needs to render the object. So far so good. But a Renderer3D would need to get an Object3D argument, in order to get not only the basic attributes but also the specific attributes of a 3d object. Constructors would look like this: CRenderer(Object& object); CRenderer3D(Object3D& object); Now how do I specify this in a generic way? Or better yet, is there a better way to design this? I know I could rely on RTTI or similar but I'd like to avoid this if possible as I feel there is probably a better way to deal with this. Thanks in advance!

• Is marshaling/ serialization in PHP as simple as serialize($var) ?

  - by Ygam

  here's a definition of marshaling from Wikipedia: In computer science, marshalling (similar to serialization) is the process of transforming the memory representation of an object to a data format suitable for storage or transmission. It is typically used when data must be moved between different parts of a computer program or from one program to another. I have always done data serialization in php via its serialize function, usually on objects or arrays. But how is wikipedia's definition of marshaling/serialization takes place in this serizalize() function?

• Mapping of interconnection with nhibernate

  I have to describe interconnection between objects. public class Entity { public string Name {get;set;} public IList<Entity> Connections {get;set;} } How can i persist this? I add another layer of complexity: querying on a specific date a connection between two entities can't be already defined. So probably I need a support table that contain a structure like Id, Source, Destination, ValidFrom, ValidUntil Mauro
