I'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?
how can I extract a certain words from a sentence input by user. For example, when a user enters "Jones born in 1965", the program will extract the words 'Jones, born, 1965' while eliminating the word 'in'.
I want to extract certain words from a sentence input by the user. For e.g., the user enters "Jones born in 1967" and the program will extract the words 'Jones, born and 1967' but will not extract the word 'in' and will print the extracted words out.
Code: Public Function convert(ByVal sentence As String) As String Dim conv As String = sentence conv = Replace(conv, "I am ", "you are") conv = Replace(conv, "I'm", "you are")

This works to some degree but a word like "Mommy" becomes "Momyour". Or "mean" becomes "youan" How can I do this with full words only? I've tried putting spaces before and after within the quotes, but then any of the words that need changed at the beginning of a paragraph, don't change because there is no space at the beginning.
I'm wondering on how you would go abouts instantiating a class that contains other complex objects. for example an Payment Class which has Date,Time, etc.. and it also holds a reference to a paymethod object which has id,Type,Description etc.. How do you instantiate the payment class with all the other objects without one or the other failing, how do you create the payment class which doesn
I'm trying to create a program that produces random sentences as output. With five arrays of strings, one each for nouns, adjectives, verbs, prepositions, and articles. Each array should hold several words for that part of speech. Like, the Articles array could hold the strings "the" and "a"; the Nouns array could hold "Martian", "baby", "skunk","computer" and "mosquito"; the Prepositions array could hold "around", "through", "under", "over", and "by"; and so on.
It's supposed to generate sentences by randomly choosing eight words (randomly generating eight array indices) from these arrays, always constructing sentences by using the parts of speech in the following order: article, adjective, noun, verb, preposition, article, adjective, noun. Also, the code should be properly modularized so that the code to generate each part of speech is not repeated.
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?
I was created data bound grid with 5 colmns. And two cmds buttons and entered 200 data in all colmns. In the colm-5 text enter three or four line sentence like Seeta Rama Rao The following code to find the data of the rows and colmns.
After I input a few sentences in a textbox, I need to find the longest sentence in the textbox by clicking a button. The longest sentence should be displayed in a MessageBox.
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.
If I have a class that inherits another class in which there are objects that are disposed in the dispose() procedure, do I use mybase.dispose? ex Class A inherits Class B. [code]
[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?
1) Add a Private variable named _area2) Associate the _area variable with a Property procedure called Area3) Change the CalculateArea method to a Sub procedure. The method should calculate the area and then assign the result to the _area variable.4) Include a parameterized constructor in the class. The constructor should accept one argument: the side measurement. After using the Public property to initialize the Private variable, the constructor should automatically call the CalculateArea method.At this point I believe I've completed the first 2 steps for the Square method, but I'm not sure where to go from therHere is my code for the Square class and the Main Form, in tha order:
Public Class Square Private _side As Integer Private _area As Integer
1. Write a Visual Basic Console Application which creates two DateTime objects. One DateTime object should be used to store a value for date purchased. The second DateTime object should be used to store a value for date paid. See below for more information.
2. Assign values to the two DateTime objects.
3. Use the toString method to display the two DateTime objects.
4. Compare the two dates to determine which date occurred first.
5. Compute the number of days elapsed between the two dates.
6. If the date purchased occurred before the date paid, display: The number of days required to receive payment was ________. Replace the _________ with the number of days computed between the two dates.
On the other hand, if the date paid occurred before the date purchased, display: The number of days this order was pre-paid was _______. Replace the _________ with the number of days computed between the two dates.
If the two dates are identical, display: The payment was received on the same date as the purchase.
I'm having a problem at the moment developing my application. What i need to do is find out how many modems they are connected to my system and send data to each one in turn. I have the programme working for one modem at the moment.
So I can send data to a modem that i specify, for example a modem on COM port 1. I have functions already that will give me a list of COM ports that I need to open.My problem is that i want to dynamically create a new modem object along side existing modems and store them in a collection.
I have a question. I have a class of Cars that I need to display in a simpli-ish string if they will be sold or not base on their number.
[Code]...
I'd like to display a simple string like this:Cars to be sold: 1, 3-5, 7-8, 11, which is based of the .Sell value.Is there some kind of heuristic to create this kind of string in .NET or is it just a bunch of for/each and if/then and redimming of arrays?
I have decided I would start small and make a program that would create a "receipt" list in a listbox and a total. Now, I would like the user to be able to add their own "menu" items. I'm assuming the best way to go about this would be to have them actually add it to a database and then a function in the program will refresh the dataset with the new list. However, this is where my problem lies. How can I tell VB .net 2010 that I want to create a new button (or buttons) on the fly, in an orderly pattern on the form, based on the input from a DB?
I would like to dynamically create an object (in my case a thread) and then be able reference that object. Simplistically put, I would like to read from a text file and then process each item using a thread (so that I don't have to wait for each item before starting the next). The problem is that I cannot think of a way to create a new thread dynamically ie. thread name so that I can then wait for all created threads before doing something else.
Is there a way to dynamically create an object at runtime?Background: Basically i have an employee class that i want to instantiate every time an employee logs in. What i don't want it to have an employee object already created for every employee, but when they log in the object gets created.
I have a Clients master object and then a number of child objects whose exact number is not known in advance such as Client-Contacts, Client-Payments etc, all of which have a one-to-many relationship with the Client master object.How do I define classes for such a scenario? Do I for instance create the master Clients class and can then I create an array of class somehow for child objects?
Is there any way to use a LINQ to XML to query an XML document like the one below to create new (anonymous or strongly typed) objects from the child elements of a descendant? Here is my XML document:
I am in the process of learning LINQ to Objects. I am querying an array of reference elements using LINQ. In the code below, which I have marked with asteriks and PROBLEM, I am having difficulty returning any values for and I suspect its because of the multiple Select arguments.

I am trying to populate a dictionary with objects created from data in a recordset, but am having difficulty with VB's object referencing. I am very new to VB. Pseudo code of what I am trying to do:
dim dict as Dictionary rs = getRecordSet while rs.moveNext set myObj = new MyClass myObj.properties = rs.relevantFields dict.add myObj.getUniqueKey, myObj wend
However, all 'objects' in the dictionary are actually references to the most recently created (and thus last) object in the dictionary. I know why what I am doing above is not working, but I don't know the correct way to do it so that each element in the dictionary is it's own object.
I'm creating a list of labels dependent on a few variables based on search results.Say I have 10 search results, 10 labels will be created within a for each statement, however I want to create subroutines for these 10 labels with an onclick event, is this possible
I've createda vb.net class library where I've defined a number of small classes... nothing complicated, just working with strings, sending emails, etc.In another project, I reference the class library and I'm seemingly able to create an instance ofone of tclasses - intellisense shows me all of the plic properties, methods, etc... all looks perfect. No compile errors at all, nothing b gumdropsand lollipops.When I run the app I'm working on that references the class library, it fails at the point where I'm creating an instance of the class and gives me a vague exception, "System.TypeLoadException".
I'm pretty new to the EDM, so bear with me. I have a windows form that has a DataGridView on it that's bound from the EDM I created. I figured out how to update my changes fine, but it's when the user creates a new row that I'm having a problem.I tried numerous ways and many google searches, but came up with nothing so far.

I've been working on creating forms and objects through code in the the load event of Form1, truthfully theres a few questions I have under this one category but to start I want to create a button click event that will check what button was pressed then set that button to a variable. I want the event to treat the button that was clicked like it was that buttons click event.Here's a shortened version of my code (Lol if you can call this short):
