I have this code to pick a random number Between X and Y
X = Minimum Number
Y = Maximum Number
But the problem is i wanted to know if there is a better random function than the one i have.
Because right now i put
Min = 1
Max= 2
and it keeps picking 1
if i had min =1 and max =2 i want it to pick 1 sometimes and 2 sometimes
and now i tried min = 1 max = 3 and it never picks 3, it only picks 1 and 2
ok
Public Class Form1
Public Function RandomNumber(ByVal MinNumber As Integer, ByVal MaxNumber As Integer) As Integer

So what I'm trying to do is not so much generate a random word but pick one from a collection. I was thinking on generating a random number since that is very easy, then picking a word acording to the number generated. Is there a more efficient way of doing this?

I am not so good at VB.NET, well, I am working with a school to run a Spelling Bee aimed at children in year 7. And to make it fair and unbiased i need an application that can choose randomise a word from the list box then transfer the string to the text box. So basically something that can pick a random string from the listbox and show it in the textbox1.text property.

I need to have two pieces of software, made in vb where one encrypts the contents of a .txt file, and the other decrypts it, and then picks one word at random and displays it each time a button is pressed, but never displays the same word. Or, if there was a way to hard code it into the program as there is only 5 words that would be better.

I am new to VB and what I would like is for the user to pick a item from the drop down box and from there; there would be a list that pops up to the side with that users pick list of attacks. I am trying to do this for every item in the drop down box. So, when the user changes character type it automatically changes the list to what the user picked. Below is two pictures one with the ?amazon? picked and the other with the ?sorceress? picked. To give you an example of what I am trying to do. My question is what the best way of doing this?

how to have the code randomly pick a memory location in an Array without having it filled, perferably in VB.NET Thinking of the logic, I was thinking
Dim random As Random
Dim tic(2, 2) As String
random.Next(tic(2,2))
Would putting the array as a parameter would randomly pick a memory location in an array?

I have an array with 280 items in it. I only want 140 of those, so I want to pick them at random. So I need to generate a random number between 0 and the source array's getupperbound property. I think. Is there a more suitable way to pluck an item from an array. I wonder if there's a way to ensure that you don't choose the same item more than once. I suppose I could randomly sort the source array and choose the first 140 items, that would ensure I don't get a repeat item. But could be inefficient if the source array is much larger than the destination array, because I'd be shuffling more values than I need to shuffle. I suppose it's a sampling problem.
