Firstly we need a deck object which in my case is a queue of type card. My question is relating to the card object.Would it be good programming to contain the card image within the card class so that the card object could be placed direct into some container or is it best to handle the card image within the main class.

I have found so many such as tustena but unfortunately they are not domain driven based and in these solutions I could not find a good modelling documents or references. i am a newbie in CRM but I am sensetive to design it with solid object-oriented fundamentals. Any reference or open source solution especifically for CRM design and implementaion in .NET? Cheers

[Code]...
Our company currently uses an APL model to illustrate our life products. We are in the process of converting this to Excel/VBA because the APL system is extremely difficult to maintain.APL is difficult to maintain because the code has become over the years (~15yrs) spaghetti and only a select people (who have worked here 5+years) really understand this to make updates when new products come out. APL is also not well known and difficult to understand. I just would like help on designing the system, my main career is not a programmer, and the design I was envisioning was a "Procedural" approach. (the APL is procedural rather then object oriented. I have not used object oriented code before)Basically the program illustrates a life insurance product. That just means it projects a fund out from the time the policy is issued to age 120. The illustration is given to the policyholder as a way of predicting what the value of their fund will be given some assumptions.The program does the following1.) Populate Variables2.) Calculate Premiums Types3.) Monthly processing4.) Output values to spreadsheetThe system has to illustrate different types of Products and we are adding new products to the system. Most of the main structure of the program (in VBA) is already written. It seems that (#3) monthly processing will vary by product, and I would like help with maintaining that part of the code. The other 3 parts of the program are not a problem maintaining.We will be continually adding products. We will start with about 5 products and maybe add about 5 per year.Here is the Monthly Processing code:... Call MonthlyProcessing(120, PremPayMode0, Assump0, True, DumpLumpSum0)

View 3 RepliesWith this assignment, you are provided with an incomplete object-oriented implementation of the GAME MANIA software system based on Visual Basic 2008. The specification and the subsequent modelling are explained in a case study titled Game Mania: GAME AND GAME CONSOLE RENTAL STORE.
An implementation of the following classes are made available as the basis of your development work:
1.Member
2.Stock
3.Stock Item
4.Optic Reader
5.Card Writer
6.Membership Card
[Code]...
Note that the user interface provided is very basic. You need to change it, as you feel appropriate so that it will reflect the required functionality. For example, in the present implementation version, no provisions were made in the user interface for querying and handling fines associated with late returns.Providing this aspect in the user interface might be necessary as part of handling renting of games and game consoles.
This is a continuation on a different thread of mine because it got off topic. I have a program that i use select case statements, quite a few of them and did a lot of copy and pasting of code and had 5000 lines of code and was still building on it, it was suggested to use OOD so i am making a new thread related to that.
View 1 Replieshaving difficulty with understanding object lifetime / instantiation.I have a windows from with a datagridview and a panel. The datagridview has a checkbox column and a list of names which is populated from a database.The panel has a few text boxes (e.g. name, age, favourite sports team) and a 'save changes' button.
The idea is that when the user selects a person in the datagridview by checking the appropriate checkbox then the panel shows the relevant data for that person (name, age, fav sports team) by pulling the data from a database. If the user would like to update the person's details they can do so by typing in the textboxes and then clicking the 'save changes' button. All quite simple so far.
The way I have designed this is to have a 'panel' class and to create an instance when the user checks a checkbox.(NB - the reason I have created a 'panel' class is that I intend to replicate the datagridview and panel on other tabpages within my form and thought it would be useful to have a generic 'panel' class that I could re-use.)
My code looks a bit like this:
If CheckBoxClicked Then
Dim UpdatePanel As New UpdatePanel(MyForm.NameTextBox, MyForm.AgeTextBox, MyForm.FavSportTeamTextBox, MyForm.SaveButton)
UpdatePanel.GetData()
...
When the user clicks the SaveButton the data is updated to the database and I have a display message (simple textbox) which says "Update successful" and displays for 5 seconds before hiding itself.
Here is the problem:Suppose a user checks a checkbox, reviews the data and does not make any changes, and then checks another checkbox and decides to update the data by clicking the 'save changes' button. What happens is that the "Update successful" message is displayed twice.
I think this is because every time the user checks a checkbox an instance of UpdatePanel is created. If a I select five different people using the checkboxes and then hit 'save changes' I get five "Update successful" messages.
I am not sure how to overcome this. It feels like each time a checkbox is clicked I need to check if an instance of UpdatePanel exists and then destroy it. I tried using UpdatePanel = Nothing and also investigated IDisposable and GC.Collect() but with no luck.

When try to open in design mode a form (VB.NET), in which I have a custom UserControl, I see the message from Visual Studio:

The control MyNamespace.MyUserControl has thrown an unhandled exception in the designer and has been disabled.

And the form is not displayed in designer. What to do?
Im doing my first project with WinForms, and Im trying to get the DataBinding working. Theres no database in my project, but I'd like to bind some of the TextBoxes to objects' properties. In the other section of this forum (here) I found this line of C# code which does it: textBox2.DataBindings.Add(new Binding("Text", this.myPerson, "LastName"));
my question is can data binding to object properties be set up during design time (without writing code)? If so, how? P.S. I know how I would set up this binding if in WPF, but I'm forced to use WinForms.
I'm updating a large VB6 app to .Net. The database design will stay mainly the same but I'm considering making a few changes. The one I'm not sure of is if I should change how the "totalAcres" for a "User" is stored. This involves three tables(I'll only list the relevant fields),

This is kind of an off-the-wall question but does anyone know if VS 2010 has somekind of utility that will allow you to just drag & drop controls onto a form or something that will help in visual design. I'm just talking for visual purposes only. No code-behind files or anything...almost like a canvas where you can place controls and labels, etc.

View 13 RepliesI'm at a stage with my first real program where I'm putting some effort into the UI.I'd like to have a "meter", of "velocity" type, you know the ones in vehicles.I'm thinking of having an arrow that I've drawn in Illustrator pointing in a specific angles depending on values it gets from a database. i'm thinking of having on arrow pointing straight up, and two similar ones, only being diagonal in the picturebox (to the left and right respectively), thus enabling me to resize the picturebox and stretch the image. However that's not a pretty solution is it? Is there a way to place the arrow at an angle inside the picturebox, or the picturebox itself?
