View 1 RepliesCreating Array For Multiple Choice Questions
Nov 3, 2011I 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.
Public Class frmTest
Private ran As Random = New Random()
Public intScore As Integer
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
'Turns the message box invisible when start is clicked

VS 2010 VB 2010 - Program For Multiple Choice Test?
Apr 2, 2011I'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?

Jul 16, 2010I'm on my way to MSDN but thought I'd stop by here first because the answers are usually more cogent.I have a test bed that mimmicks my product app. The general architecture is a factory that builds/instantiates a number of objects (device controllers) that are scalable in number based on requirement. Each object has a threaded portion that reads a device. This way, each object can read its own device simultaneously with all the others. To perform the read, the object calls a routine in a Module that houses the device interfaces. Interestingly (and happily), it seems like each thread has its own copy of the Module routine.
The test bed seems to verify what I'm seeing in the app. In the testbed, a 500 mil second delay is substituted for the device call. Even enclosing the test module portion that hosts the delay in a Synclock results in multi-threaded execution of the pseudo device call. I haven't tested for data yet, but this seems to indicate that when the module routine is called from controller object, it too carries it's own copy of the data just like the calling object. As a long time c++ programmer...that don't quite seem right.
Creating Anagrams For A Test DB?
Mar 18, 2012I have a SQL Server DB containing real data (e.g. Customer names, ecc).I'd like to transform it to a DB to show in presentations without showing the real names contained in there.
One solution could be to transform real names in anagrams (e.g.: a customer with name "abcdefg" could become "cfadgbe") so that original name is not too easily recognizable.If you did something similar in the past (possibly in VB.NET, but C# is ok too), (If you did something different with the same goal... then it will be OK too!)

Multi-Dimentional Array - Like $something[0][1] = "test"
Jun 21, 2012I'm used to PHP where I can declare a multi-level array like $something[0][1] = "test";. I need to be able to accomplish the same thing, but I'm using VB.NET. How would I do this?
And sorry if this isn't what a multi-dimentional array is, I might be wrong at what it's called but that's what I want to do.

VS 2008 Multi-threding - Adding Multi-threading Facilities - Cross-thread Operation Not Valid
Feb 10, 2010I'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?
Accessing Multiple Sites Multi-threading Or Multi Browsers?
May 14, 2011I have a need to build an app that will access about 10 websites and pass data to them, etc.I've read about something called multi-threading when searching Google.

Write A Unit Test Assembly In C# To Test Against An Assembly Written In VB?
Sep 20, 2011Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

View 2 RepliesChoice For Server Applications?
Apr 8, 2009I 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 RepliesDisplay Choice Of Forms?
May 20, 2009I'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.

Random Row Choice From Sql Database In Vb
Jan 6, 2012I 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.

Customizing Obtaining User Choice
Jan 12, 2010sample_form.rtf (1.48MB). Number of downloads: 36. I have a working form to give specific choices to the user and retrieve the user's choice. (See code below and attached image in WordPad file.) I know I can use a global ("Public") variable to pass the text of the three choices from the calling form to the called form, but is there a way to pass these from one form to the other exclusively? Of course, my main objective is to have as little memory being used as possible. I would like to make the form in my example (frmDialogChoice) a generic form that can display any set of three choices.
code within calling form:
Dim intSwitchToMake As Integer
Dim insFrmDialogChoice As New frmDialogChoice
insFrmDialogChoice.ShowDialog()

Detect User Choice During Run Time?
Sep 10, 2010No doubt a simple question, but I'm a beginner (I learnt GW BritingASIC in 3 months long ago - but after 6 months grappling with vb 2008 I am still bewidered).
I have written a program that asks the user at run time to choose 1 of 40 buttons. These are themselves defined at run time. Whichever button is chosen the same algoritm will run (using different data). Question: To save writing the same Button_Click routine 40 times, what code should I write - and where in the program - to detect which of the 40 the user has chosen?
