Inheritance (Private Overrides Function) - Create A Class And All Other Classes Inherit From It And Modify It A Bit

Oct 15, 2011

I am cleaning up some code and I have multiple classes that are 99% exactly the same. So my understanding is that my options are...

1. Create a class and all other classes inherit from it and modify it a bit

2. Create an abstract class and all classes inherit from it and modify a bit ** I took this route

3. Create an interface and all classes Implement that interface.

Here is my 'original' class below (the one that all of them look 99% identical). This class is used in an arraylist so I have a listing of all my images from a folder I have searched.

Can't Inherit Shared Properties From A Base Class In A Child Class?

Dec 29, 2010

This is another one of my "I think it's not possible but I need confirmation" questions.I have a base class for a bunch of child classes. Right now, this base class has a few common properties the children use, like Name. The base is an abstract class (MustInherit)Technically, this means that everytime a child class is instantiated, it lugs around, in memory, its own copy of Name. The thing is, Name is going to be a fixed value for all instances of a given child. I.e., Child1.Name will return "child_object1", and Child2.Name will return "child_object2".

I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.

Inherit From A Generic Class Without Specifying A Type?

Apr 29, 2009

I have the following sample code in a VB.NET console application. It compiles and works, but feels like a hack. Is there a way to define EmptyChild so that it inherits from Intermediate(Of T As Class) without using the dummy EmptyClass?

Module Module1
Sub Main()
Dim Child1 = New RealChild()[code].....

The other way to do this would be to move the generic code out of the Base class and then create 2 Intermediate classes like this [code]...

Then RealChild would inherit from the generic Intermediate and EmptyChild would inherit from the non-generic Intermediate. My problem with that solution is that the Base class is in a separate assembly and I need to keep the code that handles the generic type in that assembly. And there is functionality in the Intermediate class that does not belong in the assembly with the Base class.

Mar 15, 2010

i'm working with different classes and different constructors. It's working fine until i try to inherit a class that also has a constructor. vb asks for mybase.new but when i add that vb says that a constructor cannot call itself, when i try it in a different way vb asks the parameters of the constructor of the class that i want to inherit.

C# - Dynamically Creating Objects At Runtime That Inherit From A Base Class

Apr 27, 2010

I am writing a game editor, and have a lot of different "tool" objects. They all inherit from BTool and have the same constructor. I would like to dynamically populate a toolbox at runtime with buttons that correspond to these tools, and when clicked have them create an instance of that tool and set it as the current tool. Is this possible, and if so will it be better/easier than creating those buttons by hand?

IDE - VB - Business Logic - Unable To Inherit Or Call The Location Collection Class

Feb 17, 2010

my form displays locations and owners for a same product, the forms have a data grid view that actually takes in the details of the location and owner of that particular product. a product can have multiple owners and locations once its manufactured over time, the forms actually display this all i need is some kind of business logic that can actually manage the historical events of the location and the owner that when a user actually goes in and adds a new entry, the end date of the previous owner gets reduced to one less than the start date of the new owner. this in formation is stored in business layers called the owner collection and the location collection, i am not able to actually inherit or call the location or the owner collection class in the classes.

Utilize Classes That Inherit The System.Data Name Space?

Mar 9, 2009

I would like to utilize classes that inherit the System.Data name space.Specifically, I would like to have classes CarColumn, CarTable, and CarSet derived from DataColumn, DataTable, and Dataset respectively.I would like to be able to add additional properities to each class. As an example this is how I would like to reference items within the classes:

CarSet.CarTable(0).Columns(0).foo
CarSet.CarTable(0).bar

I know that VB.Net is not capable of Multi-Inheritance.

Create A Class To Hold Data In Studio?

Jul 20, 2010

The problem is, I've never created a class before, not in VB, Java, or anything. I know all the terms associated with classes, I understand at a high level how classes work no problem. But I suck at the actual details of making one.[code]...

As for the Getter and Setter, the reason I put the question marks in is because I want to return the whole array there. The class will eventually have other properties which are basically permutations of the same data, but this is the full set that I will use when I want to save it out or something. Now I want to return the whole Array, but typing "Return fullDataSet()" doesn't seem like a good idea. I mean, the name of the property is "fullDataSet()." It will just make some kind of loop. But there is no other data to return.

Inheritance - Create A Method Called StartWorking() And Want FrmChild To Inherit - Method

Nov 25, 2011

I have a large problem with inheritance in vb.net. The problem is the following:

I have 2 forms => frmBase and frmChild

In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.

But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()

I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

Creating A Lot Of Class And Structure Types For A Project?

Oct 12, 2009

Is there any performance hit (or other problem) to creating a lot of class and structure types for a project? I'm not talking about the number of objects existing in-memory during runtime; rather just defining a lot of object types during design time. I find myself making a lot of small classes and structures that are little more than simply packaging a few related variables together.

How To Store Multiple Objects (of Different Class Types)

Mar 22, 2012

My brain is fried at the moment, so here's the scenario.I have a form that adds a member to my VB.NET application.When I press submit I add their details: name and number as well as what products they want (internet and phone). Internet and Phone are their own class as is member.

I want to add that they HAVE whichever they have chosen and with the member store it.

[Code]...

As what happens is once the member is created (stored) I will go to input how much they have used, and then store that. But to do so I will need access to the internet and phone classes, which are associated with said member.

Implementing Cell Class That Has Value Property Of Different Types

Jan 27, 2010

I am trying to design a table type structure that contains rows and cells. I intend the cell class to have a value property. I'm trying to work out how I can create a value that can return some defined different types e.g integer, single, date, string. I'd like the cell value to be strongly typed, but I am unsure how best to get this working.

My thinking in code so far:
Public Class Cell
Private _value as object
Public Property Value as Object // How can I define this so that it return a Type
Get // e.g. integer, string, etc
Return _value

Initializing Class Collection Of Inherited Types

Oct 4, 2010

Is there a way to have a class collection of inherited types be initialized? For example, here is my code:
Public Class CamryCar
Property Name As String = "Camry"
Property Color As String
End Class
Public Class RedCamry
[Code] .....

I prefer this one as I don't have an extra property to deal with. But I can find a way to initialize that that list with objects of RedCamry and BlueCamry. Is it impossible or is there another way to do this?
