VS 2010 Structure Classes So That The User Interfaces Though A Single Class While The Supporting Classes Are Hidden From Their View?

Jun 13, 2012

How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:

Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()

[code].....

So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:

interface.Economic.MyMethod
interface.Currency.MyMethod
etc

This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.

VB XML Classes Vs String Classes?

Oct 13, 2011

Searching the internet finds no less than 700 different ways and opinions to accomplish what I'm trying to do, and I would just like to know the simplest, most bullet-proof way possible.

[Code]...

I simply want to extract the string "bar," which is inside <hostName></hostName>I can do this easily enough with simple string functions, but I'd like to do it with one of the .NET XML classes/methods.

VB Console App Calculator?

Oct 26, 2011

I need a little help in programming a console calculator.I'll start by saying that VB is a new programming language for me. I started a class in school that uses VB to teach an introduction to computer logic and programming. It's not the first language i have learned, but it the first one that i have gotten in depth with in console apps.I have a basic set up of asking the user for the first number, then the operator, then the second number.I'm currently using a Select Case statement to start the calculation area of the program, a Do Until at the beginning of the Select Case for a repeat, then it proceeds to getting the numbers and operators.

I'm also wanting to get all the possible math operators that VB provides included.What i'm hoping for is to clean up my code and make it to where the program asks the user for the equation itself. Example.

Console.WriteLine("Enter the equation")
equation = Console.ReadKey()
