Basically what I'm trying to do is to get the program to select a text string that has 2 random numbers in it from a RichTextBox. The string it would find would be similar to this:"items_win.php?item_id=24&item_number=590576"But the bolded section changes every time the page is refreshed, so how can i find the string with the numbers every time no matter what they are?
View 5 RepliesI am making a game of tic tac toe, and I have 9 buttons lined up in a grid pattern. I want to select a random button for the computer to start the game from.
I have an array set up with all the names of my buttons, and I was thinking of picking a random entry from that array to start working from. This I have done fine, but I cannot change the text of a button. My code:
''# Define the array
random(0) = "tl"
random(1) = "tc"
random(2) = "tr"
[Code]....
as you can see, I can't simply do StartPoint.Text = "O", even thought StartPoint holds the name for the button.
The string itself contains things like "random" & random.next(1,3) & "random2" etc. The string registers all of this as a string and doesn't actually calculate random numbers.Is there any way to fix this?
View 8 RepliesIm 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. The text file is made in the following format:
20058,v,o,ED,95
20059,v,o,TI,95
20060,v,o,TI,95
20061,v,o,SL,95
First the code needes to identify the 4th element then randomly select lines from lines that contain that element. Im stuck on how to randomly select lines from that list.This is the code i have so far.

How can I generate a random string of 8 numbers and letters?
View 8 RepliesI have to (for class) make a program that generates a safe passwords for people to use. My teacher wants us to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).
View 9 RepliesI made a small license generator app with a datetimepicker, a textbox and a button on the form. When I ran the app and clicked the button to generate a license I got - 16DDD-06DDDD-09DDDDD, and each subsequent button click would get me a license with a different generated character (16444-064444-0944444, etc...).
I thought this was unusual as it should be generating a random character not a repeating one, so I stepped through in debug and the characters generated were random (161g2-06T5ip-0957H9k). I thought perhaps that I needed to seed the value with Now().Milliseconds, no luck, that still resulted in repeating characters. So I tried sleeping the thread and that generated the random values I wanted.

is their a way to do this to text? EX : 1p2a;ss4w/o4r=dg It spells out password
View 2 RepliesWhat would I put when I want it to generate random numbers and text, and has a - at the end. I know it's pretty simple but I can't think of how I would do it.
So 5 random numbers/and or text and a - at the end. So like this
The class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
View 4 RepliesSo 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 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..]
The program must generate 6 unique random numbers but when I click display numbers sometimes it gives me 6 unique numbers and sometimes I get duplicate numbers. I will add the code I have so far.
Public Class frmMain
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
[CODE]...
So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
The problem I have is I have made a program which you select a value from a combobox and it changes the value of a url for a picturebox and thus changes the picture, I also have a button which randomizes all of the comboboxes so I will get something unique, but every time the program loads, and I hit random, it chooses the same numbers in order. If you need an example, when I press random the first time I get the number 7 for my first combobox, so the selected index=7, every time I load the program and press random it picks 7 for that combobox.

I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:
-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.

Basically, I want to divide two numbers together and they should be 2 random numbers from 1-12 (I have done that part) but, the answer should be a whole number (i.e. Integer, so no decimal points etc) So, I did the following:
' Initialize the random-number generator.
Randomize()
' Generate random value between 1 and 12.
Dim value5 As Integer = CInt(Int((12 * Rnd()) + 1))
[code]....
but the problem here is that the program crashes after only a few clicks on the button. So I guess the question is: How can I make the program generate two numbers (from 1-12) that when divided become a whole number?(Is there any code that may tell the random generator that I want the numbers to be even?-so all even numbers from 1-12?)
I am trying to extract numbers from string text. e.g. 1 day (8 hours)' I need the one and the eight integers pulled out I would like to extract then store each number separately for use later. I am aware of techniques to count string text, but not pulling certain information from it.

View 16 RepliesI'm am trying to determine the total number of fields under a particular heading given that the other Heading's total number of fields are > or < than the heading in question. The query, shown first in the attached code, works well if there is one column in one database table, however it does not work well when there are a number of columns with a different number of fields respectively. The CategoriesID encompasses the entire tables contents.I devised a function to determine the total number of fields within a particular column and then attempted to incorporate this, without success, into the second query, shown in the code.
