Base 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.

I need to create unit testing project for my current website. The currentw ebsite si written in VB. All unit testing examples are using interface to create mock object. My current VB class does not implment any interface. Can I add interface and implement it to my current class and functions without affecting or changing codes to any pages in my website that call the functions? For examples my current class is like:

In re-engineering a windows forms application, I find that a lot of code-behind in the various form classes is duplicative and I'm trying to centralize as many procedures as possible into a base class which can be inherited and used by the subclassed forms.
This process seems to be going well and is making the code in my subclasses much simpler and hopefully easier to maintain, but I'm not sure where to draw the line between leaving code in the subclasses and engineering for generic resusability and moving it to the base class.
Specifically, in some subclasses I have code which manipulates variables and objects specific to the subclass, and although I could move the code-behind into the base class, the base class code references specific objects which are needed to compile. For example, each subclass manipulates a databound datagridview and form detail controls which allows the user to select between multi-record and detailed single-record views of a datatable.
In Visual Basic 2008 do I need to declare dummy data objects in the base class so that the base class will compile? Or is there a way to indicate that the data objects will be provided by the subclass?

[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?

say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?
View 2 RepliesI have a service class that i want to unit test. The service calls a repository class method in order to save some data. But before I call the save method, I have a validate method that belongs to the service class under test which validates the properies of the class to be persisted as a parameter to the repository save method.I know that to verify that the repository save method is called, i have to mock the repository class and set up the save method, but how do i verify that the validate method belonging to the service class under test is called when unit testing the method under test since they belong to the same class?

Is there a way to call functions within a class upon instantiation of that same class? Basically, I have functions within a class, but I want to automatically call some of those functions simply when there is an instance of the class created.

View 5 RepliesI have a solution with two projects within:
Company.Project.vbproj
Company.Project.Tests.vbproj
Within the Company.Project.vbproj assembly, I have a class FriendClass.vb which scope is Friend (internal in C#).Now I wish to test this FriendClass.vb from within the Company.Project.Tests.vbproj assembly. I know about the InternalsVisibleToAttribute, but that is not an option in Visual Basic .NET 2.0, as it is only available with C#, in .NET 2.0 (see here).I would like to create myself a proxy class using this internal FriendClass from within my testing assembly, so that I could instantiate it and do the testings accordingly.

I'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]
View 2 RepliesI have a simple unit test which tests that a validation function picks up a specific validation issue. The validation item returns a simple object with Item & Message properties. I've written a unit test for this function but this always fails even though I know the function works as expected.
<TestMethod()> Public Sub ContractNote_ValidateForManualInputTest_TradeOrderValueComparison()
'Can't get this test to work even though validation works!
Dim CN As ContractNote = New ContractNote
Dim Trade As New TradeOrder
[code].....
I've implemented IComparable on ValidationItem (I have a separate unit test which confirms this works). Am I Using CollectionAssert correctly?
I have written a program and have used it (in debug mode) multiple times to test it out sometimes adding code and/or changing it. After a while any code I wrote or new buttons or features I added to the form would not appear while debugging. I don't know what circumstances led to this.
The only solution I found was to rewrite my code from scratch, however, the problem came back after a while. I don't know what is going on and I can't move on without starting all over again.
Thought I had got this sorted earlier but unfortunately not. A property in a class is a collection of objects.
