I searched codeplex and google. 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
View 1 RepliesI try to convert vb.net code to an object-oriented design. This help page talks about doing it: [URL] I plan this:
[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 4 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 3 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:
Microsoft Visual Studio
The control MyNamespace.MyUserControl has thrown an unhandled exception in the designer and has been disabled.
Exception:
Cannot access a disposed object.
Object name: 'SplitterPanel'.
Stack trace:
OK
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.
good tutorials where i can read about the actual object oriented concepts which we use in real time scenarios. Not the "class is a container. fruit is a parent class and apple is a child class" kind of stuff.Recently i was developing a multithreaded GUI application in vb.net and found out many obstacles like using one form's element in another form, changing form property in other class, when to create objects to access elements and many other stuff stumped me.
View 4 RepliesI'm trying to pick up some simple object-oriented programming skills so I am trying my hand at beginner's problem - and I am totally stuck...I'm trying to write a program that will print to a label, the area and perimeter of your shape of choice, dependent on the Length and Width (for Rectangles and Triangles) or Radius (For Circles) you input and the shape you select.
I know how to do this easily with simple event-driven programming, but I'm trying to do this by using classes and inheritance.The idea I have is that you enter in length/Radius and/or width into text boxes (txtLen, txtWid) and then you can click a button to display the Length, Width and Perimeter or Radius and Circumference, and Area.
I'd create a Super-Class: Shapes to define my overarching parameters - all shapes have area and perimeter. Then I would create sub-classes for each shape inheriting the overarching "Shapes" class - dim'ing all of their respective extra pieces. Then the buttons would display the appropriate info when clicked.I understand this seems like a lot - but really I just need help getting my feet on the ground for this.

i am new to asp and am currently trying to get my head around the visual basic language and Object Oriented Programming.From what i have read you need to have a good understanding of these to create good ASP.NET webpages, but from reading about these in books and joining the website [URL]..i am getting fairly confused with the language and the OOP. Does anyone out there have any tips for me when it comes to learning about these. Is there a good way to learn about these as i just seem to be getting really confused from the start.

Very similar to how VBA handles objects, such as in Excel, I can use
Dim myBook as Workbook
Set myBook = ActiveWorkbook
myBook.Sheets(1).Range("A1").Value()
to get the value of the cell "A1" on the first sheet. This structure has been eluding me for some time now, and it would be great if anyone could suggest how to do it. I'm currently using a class and declaring all methods as Shared Friend inside subclasses, which throws warnings when I use it as I want to in other code.
The problem is as follows, a group of users (~50k) must be filtered from a DB, four fields for each user must be saved into a variable, then a second process will take each user and proceed to enable some licences into another system/platform. Both processes will be developed into the same application.
My first attempt was basically a query looping through the users but I wonder if thinking in objects is a better approach.
I was thinking in a structure inside an object to hold the 4 parameters, then pass each user object to the other object however considering the amount of data I'm not sure if this is fine.
I created a project in Excel-VBA (wich I'm also new at) that connect to a SQL. It retrieves data, puts it in arrays, calculates, writes it up nicely and mails it to a mailing list before it closes itself down. This works when Excel is stable on the server, which it is not. Therefore I'm set on rewriting it to VB.NET (just have to learn it first).Project:To build this project in VB.NET I wanted to try and make it Object Oriented (OO). I have read that OO is when I create a Sub or Module for different tasks. Are there any advantages in learning/doing this from the start? I plan on creating Subs for almost everything, and then call it from a Main sub.
Too much OO?:
These are the modules I plan to create (and call)

I have been learning vb.net for about 6 months now and I red few books about basic visual programming as most to them have information about the basic concepts like what is Object oriented programming, subroutines, functions ,inheritance etc and bit about ADO connectivity to database.
