How To Generate Unique Random Number
Aug 2, 2009
I have an application that is made for a game that you have to draw cards for. So what I have done is created a random number generator that generates a random number and then using case statements that number is associated with a picture of the card, which is displayed in a picture box. This part works fine. Each time I draw a card it is not reshuffled so I need to store the random number generated and then if that number is generated again ignore it an generate a new number.
Now to complicate matters even further when a certain card is drawn the entire deck is reshuffled and everything starts over again. Here is what I tried... I tried using arrays to store the numbers but I cannot seem to get it to search the array for the number or store the number properly within the array. The array has to be dynamic since the game is expandable and I will be adding more cards to the game in the future.

I once posted a question on generating a policy number by table ID and user selctions from comboboxes. [URL]FYI . I am doing my project in vb, that why i posted it here. I managed to do that when i choose a region and product from two different comboboxes i generate a number but now my problem is that whenever i click on the comboboxes a policy number is generated before i save the record, so if my previous nummber was 72100002 whenever i click on the product combobox i generate a number e.g if i click on it five times by the time i save the number would be 72100007. I am using a stored procedure for this. Is there another way of doing this or i might end up with my first record as 72100001 and my second record 72100006.

How would I go about generating a unique receipt number in the following range:
GA00000-GZ99999? I am not allowed to use the 'I' and 'O' letters so GI00000-GI99999 & GO00000-GO99999 would be excluded. Ideally, I'd like to create this in T-SQL but can also do it in VB.Net. This number will be stored in SQL and I can access it prior to generating the next one. They do not have to be sequential.

I'm developing a policy administration system and I need to generate a unique policy in this formart
RP000000/HH
Where R is the Region i select from a Combobox, P is the product the client chooses and the auto generated six digit number and HH is the hour when the record was entered in the system. I want the auto generated number to be the ID in my ClientDetails table in my DB.Here is my code of what I have done so far.They want to be able to tell the region and the product by just looking at the policy number.
Private Function PolicyNumber(ByVal intRegion As Int16, ByVal intProductCover As Int16) As String
PolicyNumber = intRegion.ToString & intProductCover.ToString & "000000" & "/" & Hour(Now).ToString
End Function

I know there has to be a simple way to do this but I'm not sure how the syntax would go. I need to generate a random number from 1 to 99. How do I do this? I have my attempt that failed below:
Private Sub LoadBoard()
Dim mynum As Integer = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99)
Storage.Slot1 = mynum(Int(Rnd() * 10 Mod 99))
End Sub

The object of this project is to write a computer program that will allow the computer to guess a number that you have selected. The computer will make a guess and you, the player, will tell the computer if it guessed too high, too low, or that it guessed the number.The program will also allow the player to start a new game or to exit the program. PROJECT INSTRUCTIONS:
1. Create a form with a labeled box to display the computers guess.
2. Create a new game and an exit button.
3. Create objects to indicate if the guess was too high, too low, or right on target.
4. Create program code to respond to the player�s indication by selecting and displaying a new computer guess.
5. When the computer guesses the player�s number, reset the so that a new game may begin.
I have done all as above and so far my code looks like so
Public Class Form1
Dim Guess As New Random()
Dim HGuess As Integer, LGuess As Integer, current As Integer
[code]....
The problem i ran into is that if for example a user has a number 24, when the program makes an initial guess of 50,i want to be able to click low, and the program should generate a lower number say example 22. If i then click higher as my actual number uis 24, the program should not shoot higher than a number it has previously guess incorrect (in this case 50) it should guess anywhere from 22 - 49 and in turn limit the range of the next consecutive guesses it till hits the right number. My code right is guessing as it shuold but not within the limited ranges.

I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .netI found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

I'm so confused. Please help me with this program. My teacher wants Receive a lower bound and an upper bound of a range.Also receive a number of random numbers to generate.Generate this many numbers in the specified range and keep track of how many are even, odd, negative, 0, and positive. Do not save the numbers, just the category counts.
Lower bound must be less than or equal to the upper bound (negative or positive or mix).Number to generate must be greater than or equal to 1.Use the GetInput Boolean function (written in class) to retrieve the numbers for data validation, however it must be changed from Double to Integer. Then use additional functionality to test whether they are in the specified ranges. For example, if you successfully GetInput for LB and GetInput for UB, then test LB <= UB. If successful, continue with GetInput for Number to Generate and check >= 1.

I need to use the randomize function to generate a random number between 1 and 50 for lblNum1 and lblNum2, ensuring that lblNum1 is greater than lblNum2, otherwise the randomize function needs to run again for lblNum2. I need to ensure that the user has selected an option from the gbCalcType and cboGrade first, and then the randomize function should run when the user clicks the button named btnBeginGame. How do I do this? I have this so far that generates the random numbers when the btnBeginGame is clicked:

With this code...
vb
...Dim random As Long = RandomNumber(1000000000000000, 9999999999999999)... Private Function RandomNumber(ByVal Min As Long, ByVal Max As Long) As Long Dim Random As New Random() Return Random.Next(Min, Max)End Function
...I am getting a OverflowException. Is it so that Random class can't handle Long values?

I want to create a random number with the combination of the text entered in textbox. Suppose the textbox contains bharani. So now the random number generation is the first 3 letters from textbox and the random number from 1 to 1000. So my output must be "bha876"

I am trying to create a few random numbers, but cant seem to get it to fire off.
Public Function GetRandom(ByVal Min As Integer, ByVal Max As Integer) As Integer
Static Generator As System.Random = New System.Random()
Return Generator.Next(Min, Max)
End Function
When I call the GetRandom(0,500) and display it out on the page, I don't get anything?

I am using VS2008. I worked on this problem for a time, but I was not successful doing it. Below is the VS file.I need to produce a grid of cells and have some random features as shown below which is an example of a world of (500 x 500) units (or any other size and grid size). It contains three areas (of 11 cells, Value of each cell = 108), two green areas (of 8 cells, Value of each cell = 137) and one river. The start point of the river should start from one of the world edges and finish to another one. Please note that number of feature could increase or decrease according to user inputs.The question is, how can I produce these features randomly? To clarify the question, I will read the number of areas from a form. I need these features so that the number of cells should be distributed randomly beside (attached to) each other in the world. The rivers occupy one sequential grid line. My problem is how can I randomly generate the features according to number of cells??

I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far:
