Restrict Instantiation Of An Object To Only One Other (parent) Object?

Apr 27, 2010

VB 2008 .NET 3.5 Suppose we have two classes, Order and OrderItem, that represent some type of online ordering system. OrderItem represents a single line item in an Order. One Order can contain multiple OrderItems, in the form of a List(of OrderItem).

Public Class Order
Public Property MyOrderItems() as List(of OrderItem)
End Property
End Class

It makes sense that an OrderItem should not exist without an Order. In other words, an OrderItem class should not be able to be instantiated on its own, it should be dependent on an Order class to contain it and instantiate it. However, the OrderItem should be public in scope so that it's properties are accessible to other objects. So, the requirements for OrderItem are:

Instantiation Of An Object Containing Two Other Objects

Jan 20, 2010

I am having some real issues with this one. I have a class which contains two other objects...but I cannot seem to instantiate those sub objects. Here is the code for my class:

Option Explicit On
Public Class Boot
'A collection of Heads and Shells

[Code]....

Notice the count for my two objects, Ohead, and oShell, is zero. Im not sure why this doesnt instantiate properly, as I believe is what is going on.

VS 2010 : Find An Object With Certain Attribute Value In A List Of Objects?

Oct 13, 2011

I have a list of objects, each object has a score attribute,The list of scores needs to be combined on the player ID to become a totaled score or series. My current thought process is to For Each through the list of individual games, and add the score attribute to a new list of scores with the same objects. So one list would be like:

clsGame(ID Number, Sore)
dim ScoreList as list(of clsGames)
ScoreList.Add(New clsGame(11, 244)
ScoreList.Add(New clsGame(11, 333)
ScoreList.Add(New clsGame(11, 444)

Then go through combining on like ID's to make a new list of games, that would actually be the series.

Dim SeriesList as new list(of clsClasses)
For each game as clsGame in ScoreList
'cycle through the list of series seeing if an ID matches, if so add the score onto that ID
Else

[code]....

Now I don't know how to add the player if its not in the seiries list without doing a heck of a lot more for each statements. If I add it after the end if then it will be added even if it is in the list..I tried playing around with List.Contains method, but I could only see if it contaned the exact same values i.e

SeiresList.Contains(game)

and because the scores are different (series vs single game) it wouldn't match, and I don't know how to see if it contains an object with just one of the attributes the same...

C# - Applying Attribute To Property In Business Object Such That Column Isn't Visible After Databind?

myGrid.DataSource = New List(Of MyBusinessObject)

Instantiation - Equivalent Of A Nameless Variable In C#?

Mar 31, 2011

In C#, you can do this:

new MyClass().MyMethod();

The method is executed and the reference is (typically) discarded since no reference to the object is kept.Is this possible with VB.NET (.NET v4)?

Edit: I suppose this is a better example:

new Thread((x) => doSomething()).Start();

Pass A Type To A Constructor For Instantiation?

Mar 7, 2011

What I want to do is pass a Type to another object's constructor, where the other object creates a new instance of Type. I can create a constructor with a parameter declared as System.Type without problem, but when I try to instantiate it tells me there is no such type.

Public Sub New(targettype As System.Type)
Dim Test As System.Windows.Forms.Form = New targettype

Private Variable Instantiation: When Defined Or Within Constructor?

Jun 24, 2010

I don't know if this has been asked before, but we're having a discussion about it today at my job. Should private variables (that are shared/static) be instantiated when they are dimensioned/defined, or is it a better practice to do this inside of a constructor?

Private Const HOST As String = "http://test.com/url/example"
Private Shared _Example As New OurClass(HOST)which one to use?

Flattening An Object Hierarchy Using A Shim Class - Initializing Derived Object Properties From The Base Object?

Jul 10, 2010

I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:

newProperty1 - a new string property of the derived class

flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class

Code example:

Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......

Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.

Code example:

' property names are in the string array fieldNames

'baseObjQuery is an ienumerable of baseObj

'derivedObjList is a list of derivedObj[code].....

Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
