View 9 RepliesCall Method Base Class In Program Passing Sub Class Objects?
Apr 22, 2012Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

Base Class Collection With Sub Class Objects
Jul 19, 2010[code]The reason that this is a problem is that this is a collection of EventBase objects, but I'm trying to populate it with child classes instead. For example, I might have a JumpEvent class that inherits EventBase, and this is being put into the EventBaseCollection. That means that value.GetType() returns the type of JumpEvent, which as you might guess does not equal the type of EventBase.The goal of course is to simply loop through all of the various events without having to know anything about the sub-classes. Is there a way to determine the type of the base class so that the OnValidate call will work? Or is this just the wrong way to go about it altogether?

How Many Objects Inside Of A Class Is Too Many
Jul 1, 2011I'm fairly new to the concepts of OO programming - actually programming in general as I am still a student. I'm currently working as an intern in a department that has me coding a new structure that will probably be the base for all their applications to come. So I believe I have the idea behind OO down where you create "basic building blocks" and then expand, expand and expand, until you arrive at the most complex object (for the time being). I need to put all these "advanced" objects into one but how many is too many? Can I have 100 objects inside of this bigger object if it requires all these "parts".I really hope this question makes sense to everyone. I'm sure the answer is not going to be a definite answer either but I just need a rule of thumb to go by. I'd really hate to have 100 objects inside of 1 big one if there is a better design/programming technique. [code]

Sort Of A Collection Of Class Objects?

.net - LINQ Union Objects With Same Base Class?

Return Chart.AnnotativeNodes.Union( _

The above line gets an error because I can't union List(of AnnotativeNode) with List(of DecisionNode). Each list defined like List(of EndNode) or List(of StartNode), but each class inherits from the base type Node.Is there a possible way to union these to get a result of IEnumerable(of Node)?

View 1 RepliesArray Of Objects Also Saving Variables Of Class?
Dec 21, 2011I have a small class of Object CellValue
Friend Class CellValue
Public CellColor As Color = Color.White
Public CellShape As Shape = Shape.Blank
Public CellName As String = ""
End Class
Then in my main I make an array of CellValue but I want to know if the values are also being passed down with the array.
Dim Plan(SizeW - 1, SizeH - 1) As CellValue
Dim CellW As Integer = PictureBox1.Width \ SizeW
Dim CellH As Integer = PictureBox1.Height \ SizeH
[Code].....
Are CellName, CellShape and CellColor being tied to each element in the array?. The reason is because I need to use these properties to tie certain functions to them. The CellName should have a MachineID which I would have to use to pull some info from a Database.
The Array should also be serialized and deserialized to XML as customer needs to create/edit and delete certain values in the array. And in order to save the array has to be in XML
So the Questions are does it save the CellName, CellShape and CellColor for each element, will it be affected if I serialize and deserialize using XML. If possible, how can I call up the Cellname p.e for a specific array element.
Creating Objects - Words And Sentence Class
Jun 21, 2010I'm using VB.NET (visual studio) to create a chatbox (a program that mimics a human and has a text converstion with you). Two of my main classes are a word class and a sentence class. The sentence object is basically going to be a linked list of words objects. As the program executes, many word objects will be instantiated, and so will many sentence objects. But, each class (used to create the object) has several constants, procedures, and functions defined.
For each object instantiated, are new copies of the constants, procedures, and functions created in memory? Or, is only one copy of the constants and procedures created? Since many many objects will be created during program execution (each word of a sentence will be an object), that if the constants/procedures/functions are defined in memory again and again, that I'll run out of memory. What is the best way to structure my program so that the objects created contain only the variable data, and the constants/procedures/functions are defined only once?

Mar 22, 2012My 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.
