Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?

May 26, 2011

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]......

Bug In VB 2010 RC - Class Random - Always Produces The Same Random Numbers In The Same Sequence

Apr 4, 2010

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.

VS 2010 Draw Rectangle (random Times, Random Location)?

Nov 26, 2011

I am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.

Private Sub GenerateTrees()
NumberOfTrees = Int(Rnd() * 10) + 15
For i = 0 To NumberOfTrees - 1
bmap.MakeTransparent(Color.Fuchsia)

C# - Random String Function ?

Jul 31, 2011

I've made a function in C# to create a random string, but I wanted to convert it to VB.NET, unfortunately my knowledge of Visual Basic is much less than my knowledge of C#.

Here is my VB.NET function:

CODE:

As you will see, its not much different from my C# version, except that since VB can take an optional parameter, I allow the user to select what characters to use in the string, or just use the default ones.

Here's the C# version of my function:

CODE:

Again, there's not much different, but the part I'm really struggling on is the conversion between what is the 12th line of VB code, and the 13th line of C# code. I didn't really know how to convert it to VB.NET (as I said, my knowledge of it is very limited), so I used an online converter. The result of the online converter runs with no errors, however when I try to call the function, no string appears.

In short, this C# code works fine:

CODE:

However, this VB.NET code doesn't work:

CODE:

How could I fix my VB.NET code?

Random(1) = Int(Rnd() * 10) 'Here i want to keep it as 10 values but exclude the value of Random(0)

Random Numbers And Random Strings

Nov 24, 2009

I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:

-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)

How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.

Get The Vb Random Function - Basic Winapp Application

May 13, 2010

I must say I don't get the vb Random function. Try making a basic winapp application, but a button named Button1 and a few (around 10) labels on the form. Then add the following to the forms codebehind:

Code:
Public Class Form1

Public Function RollDize(ByVal iDize As Integer) As Integer

Dim iRes As Integer

[CODE]...

Now, if you click the button, you will see that all the labels get the same number. However, if you step through the code in debug, the numbers are random.

Use The Randomize Function To Generate A Random Number Between 1 And 50

Mar 29, 2010

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:

[2008] Make Sure That Each Call To The Function Is Much More Random?

Jan 15, 2009

I have a function called DieRoll. In the function I have the following setup.

Dim objRandom as New Random
Dim intRoll as Integer
intRoll = objRandom.Next(1,7)
Return intRoll

Everything works as expected as far as generating a random number (1 - 6) is concerned, except for one problem. If I have a series of calls to the function one after another, the numbers come up the same. Is there a way to make sure that each call to the function is much more random?

Generating Salt - LENGTH Of Salt Be Random - Fixed Or A Random Number Within A (min/max) Range ?

Nov 26, 2011

VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.

Function To Create Specific Amount Of Random Numbers

Apr 5, 2009

I am currently taking a introductory level class to vb.net. For the assignment it asks to create two functions. One function should create a random number within a given range. I have completed that part. What I am having trouble with is the second function. It wants the next function to use the previous function three times so that it displays 3 separate random numbers within a given range and display it in a D2 string format.

Make An App Where Computer Generates A Random Number Using A Function?

Nov 25, 2010

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...

Get 7 Different Random Numbers?

Jul 3, 2009

i want to know how to generate 7 "differents" random numbers.

I need to use a tab() with 7 entries and verify(with a loop?) if the generated number is or not present in the the table, if not then increment a counter by 1 and add the number in the table and increment the table position by 1 for the next randomized number.

Im not sure how to do the verification, so far all i have is a function i made for the random number between min and max:

Private Function randGen(ByVal min As Integer, ByVal max As Integer)
Dim random As New Random()
Dim i As Integer
