CAI Program - Display Question "How Much Is _ X _?" With _ Being A Randomly Generated Number Between 0-9 - Label
Jan 28, 2011
Basically, I'm not sure if I'm thinking along the correct lines when trying to break this down. The program is supposed to display the question "How much is _ x _?" with _ being a randomly generated number between 0-9 which I have in a label. The student inputs the answer and clicks the "Answer" button. If he gets it right, the label below outputs "Very Good!" and automatically puts a new question in the above label. If the student gets it incorrect, the output is "No, Please try again." and the student keeps trying until the question is answered correctly.
My method of thinking on this is that the random.object generator is input first so the question with the numbers are output in the first label. Then, under the Sub answer.button, enter the statements that will either check and refer to the above statements to get a new question or have the student try again until it's answered correctly. One of the other criteria for this is that I have to use a function for the calculation. Would the function statement, because it has to return a value, go before the answer.button code or after?

In a project I'm working on, I've assigned each user a unique ID with the following code. [code] However, I want to replace the number at the end (RecordCount) with a randomly generated sequence of 4 numbers (no 2 can be the same).

Basically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work

Beginning VB 2010, had a project that requires us to create a list box of 25 randomly generated 0s or 1s. Problem is when I put the loop in, it only repeats the same random number, not different one each loop. What am I doing wrong?This is the code I have so far...Code in Question:
'Declare new random object
Dim RandomGenerator As New Random
intRandomNumber = RandomGenerator.Next(0, 2)[code]......

I have two images on my VB pictureBox one of it is randomly generated on the picBox(to any location) and the other is a normal image that can move around the picBox area using left right up and down buttons. The problem is that when ever the normal picture gets to the random one, it goes under the random picture and the task is to restrict the normal picture from going into the walls of the random one. when it gets to the wall, top, bottom left and right, it should stop moving.

Below is a form which produces a graph, the idea is to produce 6 random numbers from a range (0,6) place the numbers in an array then use these numbers to produce columns on the graph, however at the moment it is using the numbers more than once, how can I get it to just use the values once only in the array.
Private Sub btnGraph_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGraph.Click
txtAns.Text = ""
g.Clear(Me.BackColor)

I am setting up a game for my final visual basic program in my computer programming class, and it is supposed to compare what you type into a textbox to a randomly generated password, and then return whether the last character you entered had a higher, lower or the exact same ascii value as the corresponding character in the randomly generated password. Well, in order to test it, I set up labels to compare the two characters... when you type in ALT + 125, the ascii value returns 125, as it should, and it says that the ascii value of the correct character is 142. I typed in ALT + 142, and the character's ascii value, according to what the label puts out, is 196... obviously its converting dec into hex or oct or something... but how do I fix it?I can also tell you that when I typed in 196 to see if it was reversed or something stupid like that, it printed that the ascii value was 49... what's up with that?!

I am attempting to create a program that opens a file and reads the contents to then display them in a set of four text boxes (e.g. id, firstName, lastName, avg.Salary). it stores the data in an array.
i have done all that i can do, however, i wish to display in a label something similar to this "5/10 (5th record of a total of 10)" meaning the 5th record in the array out of a total of 10 records. i have already done the code to display the total amount of items in the array, that part was simple, but i can't get my head around trying to code something that will display the record that i am currently viewing in the text boxes.
i have a "view previous record" and a "view next record" button that will go through to the next or previous record, in doing so will change the "5/10" records to the next appropriate number, e.g. "5/10" goes to "4/10" if the previous button is pressed (in doing so, obviously the records that are shown in the text boxes will change to the next or previous record)[code]...

I trying to display in a label the appropriate number of dashes based on the number of letters in a word that the first player entered.
Basically, when you click play, the first person enters a word, then the second player guesses what it is. That person has 2x #ofletters of incorrect tries. I just need to figure out how to get the dashes to display based on # of letters and not a preset one of 5 dashes. The original program accepts only 5-letter word so that line of code is Me.lblWord.Text = "-----". I have modified it so the user can enter any # of chars. I tried making the above line with a lot of dashes so it but the leftover dashes will stay there and the game won't end. Here is what i have right now for my play button:
Private Sub btnPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlay.Click

I had a for a program that would grab the current url and display it in like a label or something on my VB project. I have no idea how I'd go about doing this. The thing I'd like to do is simple, but I just don't understand how...For example:
1) Click a command button on my VB Project
2) Say I'm currently on [URL] it grabs this url and places it on my VB project.

I'm working with a random number that generates a price for a house between 1 and 100 dollars (obviously very realistic).
Dim Housecost As Integer = (Int((100 * Rnd()) + 1))
My problem is that I put that number in the public class which does generate the number but only once. But I need the number to be re-generated every time a button is clicked. Now I would put this code snippet in the buttons Sub but there are 3 other subs in the code that call for that randomly generated number and the only way that I know of that allows all the subs to read this random number is to put it in the public class. So how do I put the number in a place where all Subs can read it and can be called to re-generate when needed?

I have a form with one richtextbox and one button. The idea is that:
Form Load: data read from text file into arrayButton Click: random number generated, then used to select the string whose index number matches the random number generated
My StreamReader is working correctly and I can create random numbers with no problem, but I'm stuck on how I can use this random number to extract the corresponding string. I keep get the error saying QuoteObject reference not set to an instance of an object.
My code is below:
Imports System.IO
Public Class Form1
Dim questions(69) As String
Dim i As Integer

Anyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).
Here is the code so far:
Public Class Form1
Dim word
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I 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]

Right 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.
vb
Dim r As New Random
TextBox1.Text = r.Next(0, 150)

How long it would take to generate all of the numbers between 1 and X randomly.
X=1,000,000 took 6 seconds, and for 10,000,000 took over a minute.
Does that sound reasonable?
Experiment
stopwatch start
count = 0
do while count < x
select a random number between 1 and X inclusive
have i selected this number before?
no-add 1 to count
yes -
loop
stopwatch stop
display elapsed time

I am using some arrays that are pre-filled and I am having a random number generated between 0-10. That random number will then go in to all 5 arrays and pull the item from that location. I think try to take the sentence that is generated into another string. Once that is complete I then go through the final array to pull all the sentences and concatenate them together.
Currently I've only been able to get 1 sentence to print out of 5...a fresh pair of eyes would prob see where I am going wrong...I've been at this for awhile and wouldn't mind some advice to where I am going wrong.
