View 11 RepliesI 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.

View 2 RepliesI 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

how I pick a random item from a array?Here's the little bit of code I got:
Dim array() As String
Dim words As String
words = "hello*123*abc*zxw"
array = Split(words, "*")
But what should I do next to randomly select a item from "array"?
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 have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

View 5 RepliesI have a text file that includes a list of first names, each on their own separate line.
What I am trying to do is to find a way to click on my button and have my app open the list and randomly grab a name and place it into a textbox.
I would include some code but I'm not even sure where to begin.
I'm thinking that I will need to code the button to use the openfiledialog..create an algorithm to use a random copy line and return it into the textbox.
