I'm currently quite new to VB and am trying to create a multiple choice questionnaire for work. This is a depression survey in which there are 23 groups of statements with 4 options per group. Every time a patient clicks an option, the next set of 4 questions comes up on the screen.
I'm trying to convert the old VB4 code into the new VB 2010 code. Before we were using a control array and the code looks a little something like this[code]...
I have a user control form with two text boxs, three radio buttons, and a text box for a description, but i need help trying to lik together and when the user hits the send button it sends it to a email,
View 5 RepliesI have to create a cafeteria survey application. Twenty students were asked to reate, on a scale of 1 to 10, the quality of the food in the student cafeteria, with 1 being "awful" and 10 being "excellent." Allow the user input to be entered using a ComboBox. Use an integer array to store the frequency of each rating. Display the frequencies as a bar chart in a list box.
I can get the comboBox and everthing, but it's not displaying the bar chart.
Here is my code.
Public Class Form1
'String array stores ratings
Dim ratings() As String = {"1-Awful", "2", "3", "4", "5", "6", "7", "8", "9", "10-Excellent"}
Dim studentCount As Integer 'number of student ratings entered
Dim frequency(9) As Integer

I'm not great with VB and I'm having some trouble with my University assignment at the moment.I'm trying to code a multiple choice program with several forms with different questions and then a scoring form
I'm not sure how to tell VB what the correct answer should be and how to display the scores in another form, the answers need to show how many correct in each section out of how many the user attemped to answer, so they can check scores before completing all the questions.
I need a multiple choice quiz but I've ran into some problems. So far i have 5 arrays: one for the questions and four for the answers. The question is displayed in a label and the answers on radio buttons. Problem one: I am using a random number generator to pull them but this allows them to be reused. How do I stop repeats. Problem two, my grading isn't always working.
View 3 RepliesI am in the process of creating an array for a set of multiple choice questions but I am having a few problems. I am an absolute beginner at VB and I am creating a quiz that users will select one of three possible questions and then depending on their answer a +1 value will be added to the score. However I do not know where my questions and answers are supposed to go, from what I have read online I have to use (0, 1) format to give possible answers but I do not know how I would make the questions and answers display in textboxes on my form. At the bottom of my code I have also included code to randomise the questions although I am unsure as to if it is correct. At the moment I can run my form fine without any problems but my main issue is to how I will get the questions and answers linked to my textboxes on my form.

I have to make a multiple choice and true or false quiz in VB. So i am thinking of two questions on one form.BUt i have to make the questions appear in random and not in order and make sure they dont repeat.Btw, i have searched a long time for this. I have found out how to make random numbers. But I have to make sure only 10 come and not repeated.
View 11 RepliesI am working on a multiple choice quiz, admin screen, student login screen where they choose their level of difficulty. I have been able to start the quiz, have the questions and answers filled, user answers question, check if correct or not, if correct then the score is incremented.I am able to set up a variable for 'level' and want to write some code so that whatever is selected then that table / questions will be selected and displayed to the user.
The way I'm thinking at the moment seems very long winded. I think I'll have to write an IF ELSE statement/case statement for each of the 'navigaterecords' and the sql statment for beginners, intermediate and advanced.Assume there is a variable 'LEVEL' - have not actually done this yet. Where the code refers to 'advanced' is where I have been trying it out to select questions from the advanced table.

I have a button 'start quiz' which uses the dataset to fill the quiz form - ready for the user to start answering the questions.However, I am getting a 'null reference' at the point where the 'navigate records' on the quiz form is called. Have looked up that it means I have a variable that is null. But I have declared all the variables etc. Not sure what I'm doing wrong. I am very new to programming and I have spent quite a bit of time on this already.This is the code for the student user login:
Private Sub btnLoginStudent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoginStudent.Click

I am trying to create a simple program that delivers True/False questions from a text file and then displays the mark to the student, but I'm running into trouble.I created two forms. The first contains a listbox which is populated with the possible test choices (taken from a .txt file containing only 2 choices). I wrote this code for the listbox
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Populates listbox with test names from TESTS.txt
Dim sr As IO.StreamReader = IO.File.OpenText("TESTS.txt")
lstTest.Items.Clear()
[code]....
After the test is chosen, the user presses BEGIN. At this point I have my actual Question form pop up, and the first form is hidden. I tried to begin with an If-Then statement which will open the appropriate .txt based on the selection from the first form.
Private Sub frmQuestion_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Opens appropriate test based on selection
If frmTest.txtChosenTest.Text = CStr(frmTest.lstTest.Items(0)) Then

This is where I get completely bottle necked though. I've been staring at the screen/textbook for 5 hours now and I don't understand how to write the code that will take my questions from the (now open) text file, separate the question from the answer, and put the question and question number in the appropriate text boxes. The format of the question .txt's are simple. One question per line, with the answer following, separated by a comma. For example, Midterm.txt might look like this
Question1isthisone,T
Question2isthisone,F
If I were to design a form for this problem let's say it would look like this:I am currently stuck at this part though. How do I populate the two read-only text boxes with the question number/question, and then cycle through the questions from the .txt while also keeping the user's score?
I have four drop down lists here and I've assigned the datasource and displaymemberproperties so they are populated by a table. When I run the program and select a choice, all four of them get updated with the new choice.

I am struggling to write code for single-answer multiple choice tests (i.e. Choices A, B, C, D).
View 11 RepliesI'm really new at programming and was looking for guidance about a project I have.I have to design a program that administers a multiple choice test to users. It delivers questions one at a time, from a predefined test file for the user to answer. It also marks and displays a score at the end of the test.
First, a QUESTION form verify's the user's registration status and access. The user provides a registration number and password and the program reads it from a "registration.txt" file to determine if the user is eligible to take the test (i.e., they are registered to take it). If it is correct, then the user presses the "Begin" button. If not, then a message appears and the student tries again to enter the information.
A read only text box will display the score at the end of the test (String with format correct/total) and the user can't retake the test.Second, a QUESTION form opens after clicking "Begin" on the entry form. The questions are going to be from a "testfile.txt" file.Each question is on multiple lines in the file. The first line consists of the question followed by possible answers followed by the correct answer ( 3 items are separated by "#"). The current question number and the question will be displayed in textboxes.'n'= possible answers; so each of the next 'n' lines provides a possible answer. All possible answers will be displayed in a Listbox.After the user selects an answer, an ''Enter'' button is pressed. This will submit and evaluate the answer. If nothing is selected a textbox should appear and display the error message (APPEARS ONLY IF THERE IS AN ERROR). After pressing ''Enter'', the next question is displayed.When all questions answered, the entry form is displayed again and displays the score.
I know that's a lot of information, but I wanted it to be really clear. Would it be best to cycle/loop the questions with a DoWhile loop? And how would I store the answers while the user goes through the test?
A company pays its salespeople on a commission basis. The salespeople receive $200 per week, plus 9% of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9% of $5000, or a total of $650. Develop a console program (using a one-dimensional array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson?s salary is truncated to an integer amount):
a)$200-$299
$300-$399
c)$400-$499

My gross salary formula works fine but im confused about my For Next Statement. Not sure if im doing it right. i forgot one thing.... i'm not sure if my increment counter should be where i put it. I think it needs to be in my for next statement?
i know it could sound as a silly question but i was wondering if there's a way to get data from a survey on paper though: i mean, let's say i have a survey on paper with questions and some checkbox that the user will tick and i want to get its data scanning the document and save it as pdf, if it's possible, or jpg or doc, whatever. Then with PHP or whichever language you suggest, try to get the data in some way from the scanned document and put it to a DB.
View 2 RepliesI'm new with VB programming and would like to know if anyone can look/test this code I have written. I don't have the ability to test right now because I'm at work and can't get VB installed on my desktop. This program is supposed to display the amount of gross pay for employees based on their weekly sales (if $5000 or more times 9% + $200) while using a one dimensional array.
View 2 RepliesTrying to start a discussion on what approaches forum members take when faced with the issue of writing code that calls SQL queries upon a DB. Do you tend to always put SQL in stored procedures and call the proc (and does that include basic CRUD operations) or always the opposite? Or do you prefer a mix of some procs and some coded sql? If its the latter then how do you determine which queries go where?I imagine the scale of a project can dictate some of the possible answers. I've done both and sometimes I find that quick and dirty apps that have little chance of changing or are easy to modify do not need procs. On the other hand, I generally will choose the mixed option where anything other than CRUD (i.e. workflows) will be sent to a proc. I have a particular interest in hearing about your experiences with larger projects (i.e. 100+ tables in the DB) that employ a Domain Model approach to a layered solution (has distinct UI, business, and data access layers.) However I'm interested in responses to all sizes and shapes of projects.Opinions?

View 5 RepliesI am planning a three form checklist/status report for a FEED template. Each form will address a different FEL. FEL1 is really a simple checklist and is easily dealt with using the Windows Form. My question is there a better structure to handle the more complex FEL2 and FEL3, like the web page? FEL2 will have approximately 20 questions and FEL3 will have about 50. I am still undecided whether to use radio buttons (radio button list, which I do not understand yet) or text boxes that will take a value between 0 and 10. I may weight the questions to give an overall percent complete that I can show on the progress bar or some such. If there is a better structure than the Windows form, can it and the Windows Form be linked? If not, will abandon efforts to complete current FEL1. Conceptually, you cannot start FEL2 until you have completed FEL1, and FEL3 until FEL2 is complete.

This is what I have so far. It is no working at all. No values appear when boxes checked. Would like a value for each checkbox that can be added in in order to get a total. That total to be added to the percent complete (TxFEL1).
If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
I am working on a program that takes data from a survey in the program and needs to compile it into a PDF file. Optimally it would just be a snapshot of the filled out survey. I tried using the PrintForm component in the PowerPacks section, but I need a PDF not an EPS.
View 1 RepliesI am about to start developing my second application in VB2008. The need is that it has to run on a network enviorment, probably under windows nt, the database has to be on the server so everybody uses the same data. The database is suppose to contain a lot of data on many tables, whatīs the ebst way to go? Access, SQL, foxpro dbf? Also what kind of project am I suppose to start? a windows app? or some kind of .net app.? I am sorry if I am saying dumb stuff itīs just that I am a rookie. Have in mind that after I build the application, many users have to have access to it from different computers and I also want the database to be availbale for a future website with forms and queries and stuff taken from the same database, is ASP the best choice for that purppose?
View 6 RepliesI'm developing a form that displays conference attendee data.I have a panel control on this form and would like to put a series of buttons at the bottom of this form that will open other forms in the panel. So for example, there would be a button to open the Address form, another button to open the Email form, and so on.There will be 10 buttons total. I have the Address and Email forms set up so far and it seems to work pretty slick.
Before I go any further, is this the best way to do this? FWIW, all forms will have a datarepeater control on them since there can be multiple addresses per attendee, multiple emails, etc.

I have created a small sql database using new data source. i have placed buttons to move to next,previous,first and last row but i am wondering if there is a way of making a button which would randomly pick a row with information from database or just make it randomize them before they are appearing on the screen.
At first i have tried creating random number generator and then joining it with the coulmns in the database. I failed in the end even though i thought it was going to work. Then i thought maybe i have to change the query as in, instead of "Select that and that and that from database" i thought i have to write "Select that and that from database sort by rand", i also saw that some people write limit 1 or more afterwards but i have no clue what it is and didnt use it. Anyhow i tried that query and it didnt work.
EDIT: I also thought about adding all questions into array, or use some sort of indexing, but i have to use database as the requirement.
Also if anyone would be willing to give me an advise of what is best book i could buy, which would cover databases in sql and some beginner/intermediate programming in visual basic.
I made a combo box and i need to know how to set one variable for each choice in the combo box. for example, my choices are poor, average, good, and superior. I want to set the "poor" variable as the poor option in the combo box and the "average" variable as the average option in the combo box and so on and so forth.
