Accomplish Is When The User Presses A Button, "moneyamount" Increases By A Random Number Generated?
Jul 4, 2009
the goal i want to accomplish is when the user presses a button, "moneyamount" increases by a random number generated. the problem i am having is that after the action is finished the script does not seem to save the new value and always starts at zero. here is the script:
Private Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dojob1button.Click
Dim moneyamount As Integer = moneyamount + Int(Rnd() * 10)
moneylabel.Text = "$" & moneyamount
End Sub
I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
i've created a hangman game (Fully working) but since you can only "play" with one phrase (10 letters) it gets boring fast. Basic the current game works by on form load i define the slots (10 string which each hold a letter) and give them there letter. then the user type in a text box and if the textbox = any of the slots then the lbl repasenting that slots changes its text from "_" to the letter.
Anyway what I would like the button to do is when the user presses the start button a random number is generated. The program then looks into a textfile and based on which number is generated it takes a certain line (10 characters per line in a phrase) , moves them into the slots and the game starts. Is that possible to code or it too complicated. The textfile will be in the applications folder (words.txt).
I am using some arrays that are pre-filled and I am having a random number generated between 0-10. That random number will then go in to all 5 arrays and pull the item from that location. I think try to take the sentence that is generated into another string. Once that is complete I then go through the final array to pull all the sentences and concatenate them together.
Currently I've only been able to get 1 sentence to print out of 5...a fresh pair of eyes would prob see where I am going wrong...I've been at this for awhile and wouldn't mind some advice to where I am going wrong.
Public Class MainForm
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I've got a global random type variable, let's call it rRandom.In my code, I generate a random number like below:
Dim iRandom As Integer = rRandom.Next(0, x)
9 out of 10 times iRandom is 0, the other time it was 1. The code isn't on a timer, it happens when I do something (say clicking a button), so the frequency of the code being called is about 2-3 seconds, I say this because I've had similar issues when generating random numbers really fast in a timer, or with a for loop IIRC.X is a variable that, presently, starts at 3, and will decrease until 0, in which it'll return back to 3. Obviously, if X is 0, iRandom will be 0, but it shouldn't be 0 all the time.I'm declaring the variable globally because I remember, again, having similar issues using local variables, idk whether I should be or not.
I am trying to generate a random number during testing using NUnit, but it keeps generating the same number. I am using the following function for this purpose.
dim dCount As Integer = Math.Floor((High - Low + 1) * Rnd() + Low) dim divName As String = "abc" & dCount
Right so my generator is working, but I now want to take the numbers that it generates and add them to a list of generated numbers. So you can monitor what numbers have been generated. then ideally a way to exclude these numbers from being generated again.
I made a tic tac toe game. and i was wondering how would code it so that when a user presses a button or when a user wins it makes a beep or some kind of music
Beginning VB 2010, had a project that requires us to create a list box of 25 randomly generated 0s or 1s. Problem is when I put the loop in, it only repeats the same random number, not different one each loop. What am I doing wrong?This is the code I have so far...Code in Question:
'Declare new random object Dim RandomGenerator As New Random intRandomNumber = RandomGenerator.Next(0, 2)[code]......
how to send e-mail?I don't know what's the code for send e-mail. Can anyone teach me how to?I have a button on the Menu Tool. I want when user presses that button, it will directly link to the Microsoft Office to send e-mail to me.Please teach me.By the way, I also want to know how to load a text file. I want to make another button on the menu tool so when user presses it, a text file will pop up.
I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?
vb.net Option Explicit OnOption Strict OnOption Infer Off Public Class frmMain Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click Me.Close() End Sub Private Sub txtGuess_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles
I am trying to create a lotto simulation, but don't know how to continue.I am using numericupdowns to allow users to select 6 lotto numbers. and labels to display what they have chosen, but i'm not sure how to prevent duplicates without creating a large number of If statementsMy question is, is there an easier way to prevent duplicates without writing a bunch of if statements?here is my code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Lotto1, Lotto2, Lotto3, Lotto4, Lotto5, Lotto6 As Single Lotto1 = Val(NumericUpDown1.Text) lblLotto1.Text = Lotto1 Lotto2 = Val(NumericUpDown2.Text) lblLotto2.Text = Lotto2 Lotto3 = Val(NumericUpDown3.Text)
[code]....
I don't understand how to save the user selected numbers, let the computer generate 6 random numbers, and match the two sets of numbers together to see how many matches there are. As far as I understand the numbers should be stored in 2 separate arrays and then matched together to find any matches.
I have a simple question that most could probably answer. I have a button that when it is clicked it transfers information from that form to a microsoft word doc. Now what I want to do is everytime that button is clicked it creates a number that is displayed on the word doc. So this is how it would go:
first click- it would show a number 1 on the invoice.
second click- it would show a number 2 on the invoice.
This would continue as long as the program is used.
in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.
I need to create a program that rolls a dice a user generated number of times and give the frequencies of the numbers that come up.I cannot for the life of me figure out how to get the frequencies?
What I'm trying to accomplish is for the user to select a menu item(New Tester) from the MainForm(only used for menu)to open the NewTesterForm and enter a rating from 1 to 10( 10 being the best) for two different drinks. When the user clicks the ok button on the NewTesterForm it adds the new rating to the totals. It keeps adding the rating totals until a user clicks the cancel button which returns to the MainForm. When the user clicks on the MainForm menu item Summary, The SummaryForm opens and displays:
-average rating for each drink which drink had a higher rating(the name of the drink)the total number of testers
1. I need a button to be clicked and generate a random number2. I need to take said random number and store it in a place where I can access it from a timer.3. I scan for a webpage and if the webpage is true then I need to output said random number. One time
I was working in a Game in VB, and I was making a Loop that will start when the game begin and end when someone win.But then I found a problem:I have my main code in the loop and a Randomizer that starts when a button is clicked.So my problem is that I can't work whit the random number in my loop. How can I access the random number (it as to be choosen after a click of a button) in my loop?!
Im working on writing a program for doing standard deviation and as of right now im running into one slight issue with subtracting my mean from the original numbers. I will post most of my code so you can get an over view but i mostly just want help on this one little part for now. Im going to be making a website for school and put some programming stuff on it so i wanted to make just some random programs for it so this is school related but not really homework. It's line 26 and 27 that this is relating to. When i put a stop in my code and look at the result of arrayDifferences it gives me 0.0 when it should be -1. I know i can go this route and say arrayDifferences(1) = arrayDifferences(1) - arrayAvg but seeing as how i want this to be a random number of numbers input by the user i cant do that.
I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file. All I could come up with is generating ONE random number, but I can't figure out how to make it 100. Here is what I have:
I'm trying to work out how to detect if the user has pressed an f key I have this so far:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress Label1.Text = e.KeyChar End Sub
This detects when the user presses a character key and outputs it via Label1.text, but it doesnt work on all keys?
I have a code that generates random code using a set of letters. One for a random pin and another for a random code. I can loop the generation of my codes depending on the input. When I try to generate 1 to 3 set of codes it works fine. but if it's 4 and above. I always get a duplicate set of random numbers. I don't what wrong. My code for generating my codes are in vb.net and be passed to a stored procedure for inventory.
Button event: Protected Sub genCodeBtn_Click(sender As Object, e As EventArgs) Handles genCodeBtn.Click connection = accDB.databaseConnect()
I am writing a function that should sound a beep every two seconds until the user either clicks the mouse or presses any key. The code I have written appears to work for the mouse click, but it ignores keystrokes:
i want to make a message box appear when the user presses Alt k (then) Alt e (then) alt j . is this the correct code to use?:
Private Sub form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txt3.KeyDown Dim intcount As Integer = 0 If e.Alt And e.KeyCode.ToString = "k" Then intcount = intcount + 1
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
