I have some classes, BsfciFile and StudyFlashCard. Bsfci is the extension to which I save my set of flashcards in an INI format. I am currently working to transform my code from using Windows API calls to access the INI to using a IniFile class that I found on the internet. I would like the BsfciFile to have a Array of StudyFlashCard objects, but I would like the StudyFlashCard class to use the IniFile class object contained in the BsfciFile class. I can pass the IniFile from the BsfciFile class to the constructor for the StudyFlashCard class, but I want it to modify the same IniFile as the BsfciFile class has later on.

This is a bit of a continuation from a previous post for which AtmaWeapon was very informative.
Problem:
A parent class has a sub class with various properties. A property of the parent class is a List(of T) with T = the sub class The issue is how to store data in the sub class of the instantiated parent
Some example code (hopefully formatted correctly):

View 1 RepliesI have a very simple class that is located within my App_Code folder in my VS2008 web application project. I am trying to instantiate an instance of this class from my code-behind file. Intellisense does not seem to be seeing my class and I am not sure why. I am using VB.NET which I am admittedly not that familiar with as compared to C#. Perhaps I am missing something. I would bet it has something to do with something I am missing in VB.NET.Here is my simple class (for testing):

Is it possible to set a variable in my custom class for Private Read/Write access and Public Readonly access without creating Properties with Get and Set? In other words, from within my class I want full access and from my form I only want read access. Right now I declare my variable as either Private or Public to control Public read/write access. I tried googling my question a bit but I'm not sure what the correct terms even ar

View 3 RepliesI am creating a simple XML web service and have run into something I can't quite explain.My web service class has the following structure :
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
[code]....
Invoking my method using the built in VS web service test harness works fine. I created another project, in another solution, to test consuming the web service. I added a web reference to my project and set it so I could reference my web service by using "localWS". Then in the page load event of my consuming class I tried to instantiate an object of my web service:
Dim srv As New localWS.MyWS
But there was no "MyWS" type found. There is however a localWS.MyWSSoapClient class. When I use it I can invoke my web methods. My question is, why can't I create a straight up version of MyWS class? In the tutorials I'v read, and in the book I have, example consuming classes for .NET XML web services can instantiate objects of the web service class they are consuming. As a further test I added a new web form to my web service project and from there I was able to instantiate a MyWS class.
I've encountered a problem which challenges my understanding of access modifiers in VB.Net. I have a class declared Friend. If I declare its properties Public, the application works. If I declare them Friend, the application fails.
Before this, I believed that, in a class declared Friend, it would make no functional difference whether I declared the members Public or Friend. I thought class access declarations applied their restrictions to all nested entities, so nested properties declared Public were effectively restricted as if they had been declared Friend. Obviously, I was wrong. Can anyone explain how access modifiers really work, or point me to the relevant documentation?
Here is a more detailed description of the situation: I have a Friend class called StripTask with properties called StripDate, HistorianDate, and TaskText. I have a collection of StripTasks (called _StripTasks) which is used as the data source for a Syncfusion GridDataBoundGrid. The way the binding works, I need to pass the name of a StripTask property to each of the grid columns so each column knows what data to display. It ends up looking something like this:_DataBoundGrid.GridBoundColumns(1).MappingName = "StripDate". When the mapped properties are declared Public, it works. When the mapped properties are declared Friend, the grid is populated with the correct number of rows, but every cell is empty.
As a follow-up question, is it a good idea to avoid things, such as this Syncfusion binding method, which require me to pass property names as strings? It just feels as if I'm inviting trouble.
I want to do this: [URL] but in VB. I believe that is for C# I have 2 classes.

View 3 RepliesI have two classes in two files in a class library project, they are:
Public Class Logins
Public CurrentUser As Login
Public Function Authenticate(ByVal id As String, ByVal pw As String)
[Code].....
So, I am reorganizing a winform application I wrote to make it more readable and maintainable. The previous structure I used had:
1- a login form with some connection objects
2- an import process start form with some import objects
3- a log writer class that receives data from the import process and writes a log file at the end of the import process
The code quickly got too messy, so my goal now is:
1- a login form with only form events
2- an import form with only form events
3- a class with all the functions
Basically, my class with all the functions (3) looks like this:
Public Class MyProgramMainClass
Public Function test()
Dim testing As String = "test"
