It's a simple 3-Tier Structure Windows Form Application using Visual Basics 2008 express edition. I need to populate a ComboBox (User Interface Layer) using an Array with only 3 names (Data Access Layer and Business Logic Layer). I think I'm close to it but I'm unable to pass the data from the DAL all the way to the UI properly. When I run the application, My ComboBox gives me choices but the three choices are

The application uses ADO.NET to invoke sprocs for nearly every database operation. Some of these sprocs also contain a fair amount of domain logic. The data access logic for each domain entity resides in the domain class itself. ie, there is no decoupling between domain logic and data access logic. I'm looking to accomplish the following:

I have 20 radiobuttonlists on a page. Each has 4 options with values 1, 2, 3 and 4.What I need to do is on submitting the form, get the total value of all the radiobuttonlists (eg 3+1+2+3+4...) divided by the total number that have actually been filled in (none of them are required fields so anything from 0 to 20 of them could have been filled in) - hence getting an average value.
View 1 RepliesI've got a strange questions and more than likely a simple answer so here goes.I have created a few web forms that hook up with a table and save the values of the selected radiobuttonlists. In a few cases there may be a few listitems that have the same value but different text such as

Is this a correct syntax?? If yes can someone please give the VB version of it??

What im trying to accomplish is I have a table which im creating dynamically and I want in the first tablecell a radiobutton, second tablecell first name, third tablecell last name.The second and third tablecell work fine but having trouble with the radiobutton. Im making it a radiobutton list b/c only one name should be selectable. Below is how im creating the radiobutton list. I have omitted the second and third tablecell as its working properly. The yesNo variable is used to say i

This is in ASP.net iwth VB.I have a quiz project that I've been assigned for work.This quiz project contains two main SQL Databases it pulls the info from. First is a Quiz table, which contains three columns: QuizID (Pri Key), Title, Description. This is where I declare the quizzes, indicated by the QuizID (1, 2, 3....etc)
The second table is the Questions table, containing the following columns: QuestionsID (Pri Key), Title, Answer1, Answer2, Answer3, Answer4, Answer5, CorrectAnswer, QuestionOrder, QuizID....The QuizID in the Quesitons table matches the QuizID in the Quiz table.Thus for QuizID = 1, it consists of all the questions with the matching QuizID in the Questions table. The CorrectAnswer I want to assign a simple value (1, 2, 3...etc).I need a way to take a set of questions (based on the QuizID) put them in some sort of table and randomize them (or rather shuffle them) so that each time this quiz is taken, it pulls all questions randomly, but not repeating any)...I then want the code to pull the question and coorepsonding answers to pick from in a radiobuttonlist. However, It only needs to pull the number of answers. Example, a True/False will only have Answer1 and Answer2. The other Answers will have the NULL value in it.
There needs to then be a way to go through each one of these questions that have been placed in the table (in that random order) using a "next" button. When a question and possible answwers are displayed, I alaready have code to keep the answers in the session to grade it at the end (using correctAnswer and selected answer.I have no specific way to bind the data to the Database. I have used SQLDataSource to make other connections before, but I don't know if this is the best way.
I have a form with contains, among others, a TextBox called "wmi_cell_phone" and a RadioButtonList "wmi_send_sms". Basically, I need to create a validator that checks whether the value of the selected radio is "Y". If this is the case, then it checks if the TextBox value is empty or not. If it is empty, then it should notify the user to enter a value.

I have 20 radiobuttonlists which are dynamically created - then declared when a form is submitted. I also have some code which totals the number of answered questions and the total value of the answered questions. - this code used to work when the radiobuttonlists were hard coded into the page, but it now does not. - I am writing the number of questions answered and the total value of all answers to the page but they come back as 0. Why this might not work now that the radiobuttonlists are dynamically created.?
Code behind:
Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)
For i As Integer = 1 To 20
Dim TableRow As New TableRow()
Dim TableRowCell_1 As New TableCell()
TableRow.Cells.Add(TableRowCell_1)

I am trying to make a webform that will act as a "wizard". My problem is how to get the program started e.g. I want to ask the user a question and have them choose a radio button, then have them click a next button. when the user clicks the next button I want to use the radio buttons as a condition so for example if the user selected the "yes" radio button then the program will display some new labels and textfields or radio buttons and so on.

Im trying to build my first N-Tier web application. And it seems like im doing it wrong. Ive been kinda working out of this book, but to me it doesnt seem like the right way to do this. In the book the guy builds User and Data centric objects but everywhere I see ntier everyone is always talking about BLL and DAL ive seen nothign on UC and DC objects.Right now I have Interfaces and serializable structures, user and data centric objects. The data centric object does all the validation and connecting to the db, as well as returns any violated rules, but when I once i started pulling it all together it just doesnt seem right.Ive already wrote a ____ load of code and now am kinda stuck. I dont know if i am doing this right and dont want to continue writing any code if this is all messed up.Ive been reading as much as humanly possible and im still just a little confused. I mean I understand the concepts of seperating the logic into different layers and tiers and all that but as far as my implementation of that I just feel somethings a bit off.
View 3 RepliesI have a solution and I want to divide it up into Business Tier, Data Tier, etc. I think I have to do this by creating a project that contains the data source, another with the forms, etc. Every time I try to add a new project, it literally opens a new project, seperate from the first.
View 1 RepliesI usually create N Tier applications with ASP .Net applications as per the advice at ASP .Net (data tutorials). Recently ive tried to create an N Tier Windows Form database application and found the method im use to (i.e. ASP .Net) doesnt really work (unless i was doing something wrong).
View 7 RepliesI'm creating an N-Tier (or at least I think its N-Tier!) solution where I have the following:
WPF client side application (presentation layer)
WCF service hosted in a windows service (data access layer)
SQL database (data layer)
Now bearing in mind this is the first time I've tried to design anything like this, I might be going about it completely the wrong way...I've created 3 examples classes that would be my 'business objects' (im not quite sure where that fits in within the layers I listed above, because these business objects would be defined in a DLL that would be used by both the presentation layer and the data access layer). You can see them here:So then in my WCF service (data access layer) I would have methods like this that would be exposed to the WPF client:These are just examples but you get the idea. Is this the right way to do something like this?I saw one design that someone had posted somewhere that basically looked to me like it merged the Business Objects and the DAL together because in their class that represented an order, they had properties like you would expect for Order Number etc etc but then they also had methods like "GetOrders" within there too.I dunno I'm still very new to this type of design but I thought that the idea of the business objects was that they just represented business items, such as orders etc, so I thought they would just purely hold properties/fields and no methods or anything like that
i am on a project of two tier application with VB.NET + SQL server R2. except desk top applications i never done networked applications + i don't know asp.net

(1) is the encryption required
(2) what are the security measures i must take in terms of connection security
(3) how to use the server effectively with out putting much burden through good client end design
(4) any other guide lines / pit falls
(5) should i continue with vb.net or must & should switch over to asp
(6) what should be the minimum configuration of client system,
(7) Preferable is the thin client systems , is it possible to use thin clients
how can i add records using n-tier and stored procedure""
View 1 RepliesI have attempted to make my first 3 tier application. In the process I have run into one problem I am yet to find an optimal solution for. Basically all my objects use an IFillable interface which forces the implementation of a sub as follows
Public Sub Fill(ByVal Datareader As Data.IDataReader) Implements IFillable.Fill
This sub then expects the Ids from the datareader will be identical to the properties of the object as such.
Me.m_StockID = Datareader.GetGuid(Datareader.GetOrdinal("StockID"))
In the end I end up with a datalayer that looks something like this.
Public Shared Function GetStockByID(ByVal ConnectionString As String, ByVal StockID As Guid) As Stock
Dim res As New Stock
Using sqlConn As New SqlConnection(ConnectionString)[code].....
Mostly this pattern seems to make sense. However my problem is, lets say I want to implement a property for Stock called StockBarcodeList.Under the above mentioned pattern any way I implement this property I will need to pass a connectionstring to it which obviously breaks my attempt at layer separation.how I might be able to solve this problem or am I going about this the completely wrong way? I am deliberately trying to avoid using the dataset in any form.
