Quiz Program - Asking Five Questions With Yes Or No Answer
Mar 19, 2009I'm trying to make a quiz application with Visual Basic at the moment. I want to write a routine that asks five questions to which the answer must be either Yes or No. It must add up the number of Nos and if the number of Ns is less than two then print out "pessimist", otherwise print out "optimist". So far this is the design of what I've done. [URL]. However, I have no code which I've produced on my own.
Code:
Public Class Form1
Inherits System.Windows.Forms.Form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class
I really don't know how I can kind of add up all the results from each individual question, seeing as radio buttons are used.

Dec 20, 2011I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

Sep 8, 2009...until an indeterminate amount of time passes and I get "The ProviderManifestToken '5' is different from '5.1' that was encountered earlier" error. Why is it encountering a '5' to begin with when I've only specified '5.1'?!!?The only way to get the error to stop is to reupload to edmx file (which has not changed at all), overwriting the previous one. At that point the application will happily chug along serving data to users until BAM the error occurs maybe a few hours later, sometimes days later and I'll have to start chasing my tail again.I've tried changing the ProviderManifestToken="5.1" to "MySQL", "6", "5" and the same situation will occur: works for a while then the error. As a bonus I only have this ONE edmx file in the vb.net webforms application so what is it getting confused bythe first few lines of my edmx file looks like:
<edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx">

Randomly Select 3 Items To Display On A Page
Jun 15, 2010I have a class and I am trying to randomly select 3 items to display on a page (each item should be unique so that there is no repeating).I have some code that works(ish). The problem is that when I track the random numbers it takes about at least 50 attempts for the application to select a different random number than the one that was chosen the first time (defying the laws of probability).[code]

Randomly Select Which Graphic To Display On My Form?
Apr 26, 2010Right so I have made a graphic of a coin being flipped. Heads is shown on one graphic, tails on the other. I wanna set it up so that when I hit go it will randomly play one of the two graphics on one of my forms.How easy is it to add a .gif file to a form that can play when told to? What is the code im looking for to help with me with what I'm trying to do?
Another thing I plan to achieve is also a random number generator that will display a number on a ball that rolls on to the screen. So the displaying of a number will be timed to show up when the ball comes in focus. I have some code that I have used previously to generate a number, but I wanna get the generated number to show in time with the ball rolling up.What are some wait commands to use in vb .net? This is the code I am using to randomly generate a number.

Create An Application That Will Randomly Select 14 "stations" (strings) From A List Of 33?
Mar 3, 2012I am trying to create an application that will randomly select 14 "stations" (strings) from a list of 33. My thinking is that I have a for/next loop that randomly selects a number between 1,33 which is then inputted into an array (arrnumber) I then want those random numbers to then be used to call the Station name which is saved in the second array, and then for the selected stations to be populated into a listbox (potentially by storing those names selected in a new array?)
Various people have suggested either using a list (of t) instead of arrays, or a Dictionary(?) or perhaps even a database, though I am not all that confident with VB to be able to know where the best place to start with that is. So if anyone can offer any advice, pointers as to how I can link my 2 arrays (I am pretty sure I know how to make the array populate a listbox) I would be very much obliged.
Public Class Form1
Dim Stationid() As String = {"Cardiovascular Examination", "Respiratory Examination", "Abdominal Examination", "Abdominal Examination with Stoma", "Groin and External Genitalia Examination", "Cranial Nerves Examination", "Arm Examination", "Leg Examination", "Parkinson`s Examination", "Cerebellar Examination", "Speech Examination", "Hand Examination", "Elbow Examination", "Shoulder

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
Program To Randomly Select Numbers For A Bingo Caller - Prevent Reversed Numbers Being Selected
Mar 6, 2011I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
