Feb 22, 2010
I want to create an array V0(9) using random number generation. For example I generated V0(9) = {1,2,3,4,5,6,7,8,9,1} I want to use 12345 + 67891. How can I separate to use two parts of the array.
My
Public Class Form1

If 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!

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 cant seem to see what is wrong with this arrary size. It works if i set the random number to 10
pretty sure it's to do with this line For i = 0 To intResult but i cant for the life of me figure it out.
Dim intResult As Integer
'// Initializes the random-number generator, otherwise each time you run your
'// program, the sequence of numbers will be the same

i am trying to teach myself vb (im only 14), and i'm not having a easy time. What im trying to do, i need a user to define a upper and lower bound of a range. From there i need to generate random numbers, a certan number of times, with in that range...this is my first problem.And then, i need to make counters to store/test all of these variables as even, odd, positive, negative and zero's ...that i need to append to a richtextbox to show how many of each. Im not even sure if rtb is the right object to use...you know, instead of textbox, or label?the last thing was to do with Private function as boolean. do I need this to test these variable?

I have not messed with VB much and I have been trying to do something that has me stumped. I wanted to create an array of 10 random numbers. Each of these numbers then is printed onto a label. From here I have two more labels that show the highest and lowest value. I got the first part, 10 random numbers show up but then things get shaky. This is what I have thus far.

I'm working on a project that produces quite a few pdf's through Crystal Reports. The problem I'm facing is quite random. Users are reporting that reports sometimes get generated too small (report scaled down to 70% or so and printed upon the pdf) and also that some reports are being printed in landscape while they were designed in portrait and vice versa.
what could cause these random changes in generation? and maybe a solution?

My project is basically a addition test for 5 to 9 year old children. On my form I have a button which when clicked, it inputs a number from 1 to 10,( which is chosen by the user via an combo box drop down), into ten text boxes. I have built and array and used a, for loop for this and it works fine. [code] My problem is I need to create another array connected to the same button to genarate 10 random numbers. Which will allow the user to add the two numbers together.My problem is that visual basic wont let me add a second array to the same button?

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]......

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
