View 1 RepliesIf I have say 5 numbers: 1, 29, 53, 95, 103 What would be the VB.net code for randomly selecting a number of those 5.
i.e) The random number has to be 1, 29, 53, 95, or 103 and has to be randomly generated.
I've tried using the Int(Rnd() * 104), but I do not know how to make it choose only these 5 numbers!
Im making a text based game that i need to randomly select different numbers of lines from a text file then pass them to a list box.[code]...
First the code needes to identify the 4th element then randomly select lines from lines that contain that element. The code needs to work out how many lines have a matching text to the 4th array then randomly select lines from that total no need for a maximum limit to that number.The same line must only been show the once at a time, but It can then be shown again on a different button click.[code]...
So 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.
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......

View 3 RepliesI am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

I don't understand how to save the user selected numbers, let the computer generate 6 random numbers, and match the two sets of numbers together to see how many matches there are. As far as I understand the numbers should be stored in 2 separate arrays and then matched together to find any matches.
I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times

I heard that you have to add some code to a random number generator
results(1) = Int((5 - 1 + 1) * Rnd() + 1)
so that if it is used again and again it keeps generating new numbers as apposed to what this piece of code does by itself which is creates the same number every time.what is the code?
I have to create a list of 25 randomly generated 0s and 1s in a list box?Next I have to count the number of 0s and put in one label box and number of 1s in another label box.
txtTotalMem.Text = lstInfo.Items.Count
but it counts the overall amount. I need just one type. I tried using the lstRandom.SelectedItem method but you never select the item as it is just random generated numbers. The (relevant) code so far is
'Load the listbox with 25 random numbers between 0 and 1
Dim intCounter As Integer
For intCounter = 0 To 24
lstRandom.Items.Add(RandomGenerator.Next(0, 2))
Next intCounter
'Calculate the number of 0's and 1's stored in the listbox and place in appropriate labels

View 3 RepliesI have the following code which extracts the contactcode from a table in a database;
[Code]...
Code: lblUniqueID.Value() = (RandomPassword.Generate(4, 6)) Now, I want to compare the contactcode values extracted from the database and the value stored in lblUniqueID.Value(). If the random password is similar to one of the contactcode then generate another RandomPassword IF NOT then place the value to another label called lbltransfer.text.
I'll insert that value to the database.. The idea is extract all the contactcodes(these are the random passwords already generated and stored) from the database. Compare with the new generated password if it exists then create another one if not then store it in a label called lbltransfer.text.
