Date Based Sequential Number Generator
Nov 25, 2011
I have a ticketing application and I want to create a date based, sequential, ticket number.I'm leaning toward something based on Posix time as this generates a sufficiently large number and the likelihood of any two ticket numbers overlapping is slim to none (two people would have to just happen to hit the button at exactly the same time on two perfectly synchronized systems).Has anyone done anything like this or have any code snippets/ suggestions? At the moment, I'm just using a UNIX time converter someone posted elsewhere: [code] This works fine (although it's not POSIX time), but I wanted to see if anyone else had any feedback as well.

I am using VB.NET. Is there a date function that calculates the date based on the number of months I have given?
for example, if i say July 2009 and looking for 10 months back, it should return Sept 2008.

Given a week number, I need to get the date of the Monday of that week.For example, I have several strings that are stored in a file, such as
"WK 28 2010"
"WK 30 2010"
They could be any any valid week number.
The Monday on Week 28 of the year is 12 July 2010
The Monday on Week 30 of the year is 26 July 2010
Its these dates that I need.
I guess I could create a lookup table, but would prefer a more smarter approach so my software will be future compatible?

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 basically want to do what you can do for controls like the textbox where adding a new textbox automatically autonumbers itself based on the existing textboxes(e.g. textbox1,textbox2, textbox3) except for an array or some other comparable instrument.

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
Public Class Form1
Dim sex As String
Function randomfirstname()
Dim infile As IO.StreamReader

I need to generate a report that shows the 52 weeks of a year (or 53 weeks as some years have) and their start and end dates. There is an ISO spec to do this but seems awfully complicated! Im hoping someone knows of a way to do it in C# or Visual Basic (its actually for Visual Basic 6 but I will try port it across)

I have built a system for a shipping company to use that takes user input from various sources (Textboxes, RadioButtons etc) and displays it in listboxes below. What I need to do is create individual shipping numbers for each of the consignments added based on certain criteria, that being:When adding a consignment, the system should generate the consignment number automatically in the format XY12-xAB, where x is a number that increases by 1 for each consignment, AB is the Shipment Type (EA, SA or SF) and XY12 is the Office ID.
So far, I have this:
Private Sub GenerateConsignnmentNumber()
Dim sConsignmentNumber As String

I was wanting to add a random number generator to an app of mine and I have the code that creates it:
Private Function RandomNumber(ByVal min As Integer, ByVal max As Integer) As Integer
Dim random As New Random()
Return random.Next(min, max)
End Function 'RandomNumber
What I can't get to work correctly is the following. I have a textbox for the min and max. The way I have it setup is when it generates it I have a MessageBox show it but it pulls the same number a few times in a row. How do I make it pull a different number each time until all numbers a pulled. I then want to add them to a listbox as each one is generated.

I need to create a multi dimensional array comprised of random numbers between 1 and 4. The reason why I need a mutidimensional array is because each number needs to be associated with a random letter of F or N. [ F or N are really Indicators or whether I should show the user Feedback on their results in the case of F. Or not show them Feedback in the case of N.] So within this array 2 random numbers will be associated with random F's. And 2 will be associated with random N's. For example the array should look like (1,F 2,F 3,N 4,N) or (3,N 2,F 1,N 4,F). The reason why I need this random array is because during the course of my application being ran 4 times (which represents the numbers) I want to insure that every time N is done 2 times and F is done 2 times. This is all to make sure that each Number 1-4 after 100 times the application is ran has the same amount of F's and N's. I was also wondering if someone knows a way to store how many times the application has been ran in asp.net so that I can recreate another random string after 4 application runs.

Hi!
Last time this forum was the most helpful in solving my problems in vb 2005?This time I am writing a "lottery number picking" program. The program randomly picks 7 numbers from 39, with pre defined conditions on the strength of statistical data, and writes the possible combinations in a text file. It works fine, BUT- the program generates number of combinations I tell it to generate. With other words it works like
For i = 0 to 1000
generate_number()
Next i
So this way I get 1000 combinations. how can I make the program generate all the possible combinations by itself?For example:
Do while (not reached the last combination)
generate_number()
Loop
While I don't know exactly how many combinations there are, I have a slight problem knowing which the "last" combination is.

I would like to know if what I have here is correct? could it be done better? is there something I could add or take away? or is it finished and does what it does? I'm also posting it so that other beginners can maybe look at it and learn from it, just copy and paste the code in to a new Windows Forms Application, hit F5 and then Space bar.[code]

I am doing a Coin Toss program for school and I'm getting my butt kicked by this thing. The following are the instructions exactly as my instructor gave them:Use the random number generator (see the code below) to simulate a coin toss. First ask the user for the number of repetitions. Next, set up a For loop to execute that many times. Each time you enter the loop, call the random number next method. Assume that a random value <= 5 is considered a "Heads"; a value >5 is a "Tails". That is, if the random value is <= 5, add one to an accumulator named intNumHeads. If the random value is >5 add one to an accumulator named intNumTails. When the loop finished, output the number of heads and the number of tails in a text field with appropriate labels.Dim intRandom As New Random()Dim intNumber As IntegerintNumber = intRandom.Next(0, 9) In my application I have the click event of the "Flip Coin" button coded as follows:
Public
Class frmToss
Private Sub btnFlip_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

Stuck programming a random number generator game. one is to guess what the random number. I have coded most of it and am pleased, but there are some hitches. a) When running the program if you guess 10 it says," Guess Higher" which is impossible as the num gen stops at 10 (if you guess 9 and the number is lower than 9 it says guess lower . . . which it is supposed to do)
b) When asked to play again if one clicks no it calls you a loser and exits the problem is it does the same if you click yes. How can I get it to simply start over if yes is clicked
c) Does anyone know how to make an image move up or down based on the input? IE if guess needs to be higher the image moves higher? Lower and it moves lower?

how to generate a list of numbers, from 1 to 10 in a random fashion but with no numbers repeating. For example, every time the code is run, it will return an array of numbers, each different, only using numbers from one to ten?
This may sound confusing, so i will try and explain what I am trying to do with it. I have a form that displays 10 questions and each time a user moves to a new question, i want to display a new picture. the pictures will be named "picture1" through "picture10". I want the order that the pictures are displayed to be different every time.

Use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers.- develop the seve-letter word that correspondsto exactly one seven-digit telephone number. Every seven-letter phone number corresponds to many different seven-letter combinations. Mostrepresent unrecognizablejuxatapositions of letters.Write an application that allows the user to enter a seven digit number in a textBox and diplays every possible seven-letterword combination corresponding to that number ina multiple line scrollable TextBox whenthe user clicks the Gernerate Words Button. There are 2,187 (3^7) such combinations. Avoid phone numbers with the digits 0 and 1.
