I have code to save records to my mysql database.But first I want to read what is the last number of record and add 1000 on that? What is the proper way to query that first. I want to make the result at unique ID of my clients. Here is my chunks of codes.
Private Sub addClient_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim conn As MySqlConnection
conn = New MySqlConnection
With conn
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
'm attempting a program and need to generate 10 random numbers between 1 and 52. However all the numbers must be different. I'm trying this in a For Loop. I'm not terribly amazing at this so all I have so far is:
Dim B, I, J, max, min, card() As Interger max = 52 min = 1 Randomise()
[Code].....
What am I doing wrong and what is the ultimately simple solution I know the internet can provide for me?
This code is in VB6.0I have 28 numbers in sequence (eg 1-28), they are randomly generated and displayed in a label. I dont want a duplicate number displayed in the label. Pls how do I do this. Below is how I generate numbers at random. Now I want to make sure there is no duplicate number displayed in the label.[code]
I have this school assignment to generate random numbers.Can someone please check if this is the right.Also i am not able to Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters.[code]....
I have an attribute that I just added to my database to hold confirmation numbers. The only problem is they are all null so I am getting errors. Thus I need a method to generate random confirmation numbers (no duplicates). The column entries have a max size of varchar(20)
i'm programming sudoku game for my vb 8 class.but i don't know how to generate random numbers, i think that i've to use random or randomize, but i don't know how to use them, i've been looking around but i can't find an answer.and i only have this week to program it
I'm trying to make a Bulls and Cows type game, I was able to do it fairly easily with javaScript, but VB is killing me. I can get the array 5 slots long with random numbers, unfortunately they're all repeats. when I try getting no repeats I run into infinite loops, exponentially increasing array lengths, and just plain old arrays with 5 numbers randomly generated, but with repeats.
I'm trying to do this with loops, in JS I did it using regular expressions
Here's an example of my code.
Public Class Form1 Dim intRand(0) As Integer Dim RandomClass As New Random
What I am trying to do is create a form with a button and a list box. When clicked the button will generate a list of 3 or 5 characters that have alternate letters and numbers...eg.
q2h a6j z4p d9k
[Code].....
To complicate things a little, each combination needs to be different, ie. randomised but still according to the 'letter,number, letter' formula. There are plenty of examples of randomising strings such as passwords but I cannot understand how to achieve the above.

I have created a form that generates random numbers and displays them in the label box. my requirement is to show the numbers in ascending order, so i created a button for each number to be displayed in a each list box. how do i get i to display in the listbox?? Also how do i get it to check and display msg to say whether its in asscending order??
I want it so that when someone clicks a button it generates a code in the format of XXXXX-XXXXX-XXXXX-XXXXX-XXXXX I want them to be letters and numbers combinations
Trying to create a form where user enters a lower bound, upper bound, and an amount of random numbers to generate (that are between the lower and upper)
I was able to get it to generate random numbers but only 1 per a click of the calculate button...I would like user to be able to click button and it to generate and display all the numbers on seperate numbers all at once[code]...
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 am a newbie programmer and I need a way to generate random numbers for a program I am working on. It just needs to be something simple that generates a number and allows me to assign it to a variable. I would like it to be something small say 1-10 would be good and an explanation of the syntax would be helpful
i want to generate random numbers which will be put in an array and displated in a grid. the user has to provide a lower and upper bound. method overloading also has to be used in order to generate the numbers
I want to generate random numbers at regular time intervals. I am putting the random generation in a loop which works when a button is clicked. But since the Timer itself is a control, I don't know how to do it. I tried putting the timer in a module so I can access it inside the form.
But the following error occurs: "Error 1 Handles clause requires a WithEvents variable defined in the containing type or one of its base types".
When I doubleclick the timer icon the code appears as follows. Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick End Sub
I 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.
Im trying to use the library in GNU in VB2008 to generate random number with uniform distribution (actually will also use it for other distributions)...I already added dll under bin file and try to run the following code, but just cant make it work:
Public Class Form1 Declare Function gsl_rng_uniform Lib "C:vbuniformuniforminDebuglibgsl.dll" (ByVal x As Double, ByVal y As Double) As Double
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:
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.
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?
every time i press the Roll Dice button the turn1roll1, turn1roll2, or turn2roll1, turn2roll2(depending on turn variable) it shows system.random in ASCII Chart i used the label names so no confusion.[code]
