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:

How can I make a command button, When clicked, Generate 4 random digit numbers? such as 5545 or 7492, Any random 4 digits.
View 13 RepliesI am trying to write a random number function that can just be called from my main module to generate different random numbers. I have tried this several different ways and I am having odd results. Approximately 19 times out of 20 the numbers come back exactly the same, but approximately 1 in 20 they come back as two different numbers. Im using Visual Basic Studio 2008. Here is the code I have so far, or rather, the current version of my many tests I have been running to try and figure it out. Sometimes it takes many runs of the program before the two seperate numbers apear.I've been researching it and have come up with nothing so far.I know I could put them in the module section as two different randoms and it works, but I get extra points if i use a couple classes in my program.This is the main module.
Module Module1
Sub Main()
Dim randomNumOne As New RandNum[code]...........
I'm supposed to make an app where computer generates a random number using a function and then the user has to guess the number. If they get it right, they see a picture.... If they get it wrong the loop keeps going until ten guesses are up.. I'm running into quite a few problems...
1. I don't know how to tell if the photo will show up if the number is right because right now I have it set to false in the form, so it dosen't show up but in my loop I included the code that SHOULD allow it to show up if both numbers are the same.... Not sure if this is correct...
2. I have a textbox that is supposed to keep track of the number of guesses but the message automatically becomes Game Over and the guesses go up to 11 as soon as I click the Are You Right Button?
3. When I try to debug, my app freezes and I don't know why...

Making a program that generates random numbers for a "Lottery" (really for homework). Four different types of games and must show up on the GUI when click generate. My question is do you have to have different dim randomObject As New Random() for every Sub to produce different numbers? Every single type of game has different range of number. The Sub needs to return the results back as a string. If I request the method each time will I get a different number back from the range? Here is what I have but just so lost.

View 1 RepliesI am working on a Text editor. The problem I have come to, is that when a user clicks a button, I want all the text to be displayed on one line. The reason for this is I am having problems being able to upload CSV email files on a website I am working on, because the format isn't like email, email, email, email. Instead it is like
email,
email,
email,
So I have written a program that will format it. Only It still isn't working. I need it to recognise when there is a ".com," or something.
I'm running a survey to count how many times a user clicks the left mouse button. But the mouse click applies outside of the form, even applies to clicking start or other locations of the of the PC when the form has been minimized with a NotifyIcon. I know how to count the mouse clicks within a form but not outside the form. Somehow I feel I need to use a timer event but need it to apply outside the form. The timer tick event doesn't have a e.button event or mouse down event or mouse click for that matter. Whats a good way to get this function to apply outside the form?

Here's the problem I have. I want a message box to pop up if no dice are selected and the user clicks the roll button. So far the only way I have been able to accomplish this is to put the same code under each radio button:
Code:
RolledValueTextBox.Visible = True
Label1.Visible = True
Label2.Visible = True
YesRadioButton.Visible = True
NoRadioButton.Visible = True
I want to have this code only once. But If I put it outside of the If/Then bracket and no dice are selected, the msgbox pops up but also the buttons that I want to remain hidden until dice are chosen pop up. How do I get the msg box to pop up and stop...don't execute any more code.
Heres' the code so far. trying to keep it relatively simple:
Code:
Private Sub RollButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RollButton.Click
'see which radio button is checked and display random number accordingly
If TwentySidedRadioButton.Checked Then
RolledValueTextBox.Text = GenerateRandom.Next(1, 20)

I have a problem with a Save button on a toolbar firing the click event twice if the user double clicks the button as opposed to single clicking.Disabling the double click on the toolbar itself seems to make no difference as it is the actual save button that is being clicked twice.I have tried setting a Boolean to stop the event firing twice but it is just too quick!I didn't have this problem with my code before as the server call was not async... and reverting back is not really an option.
