Shuffle Array Of Numbers?

May 16, 2012

I am trying to shuffle an array of numbers it is randomizing but the numbers are been repeated is not what I need., I need the array to be shuffled but keeping the same numbers.For example if I do a first shuffle numbers may look like this in random order

2,4,5,1,3

Next shuffle maybe

3,5,4,2,1 and so on

But my problem is it repeating e.g. like this.

0,3,3,4,5 or 4,5,5,3,3

Array And Use Of Flag To Shuffle Numbers?

Apr 10, 2011

i am trying to find out how it shuffles the number 1, 2, 3 and 4 without repeating the same number within the series. So far, I think that "i" begins as 1 and RN is a randomized number between 1 and 4. The do while loop checks if "i" is the same as RN and spits out the flag as true or false. Then "i" is increased 1 at a time and so does the number of elements in the array. I believe that the array a(4) and the for loop does something that "remembers" the same numerical value not to be repeated. I'm not sure exactly what the for loop does and how the flag make this thing work.

Lets say, a case where i=1 and the RN=3, the flag becomes false. Therefore, a(1)=3. Then, i increments by 1 and a(j) becomes a(2), which puts out the values 1 and 2. Since both numbers are flag=false, it increments again. Because a(i) = RN, a(2) becomes = 3. How can this be? It has a(1) equal to 3 and a(2) also equal to 3. Each array is supposed to have NON-OVERLAPPING numbers.

The result of doing shuffle() is a random set of numbers that don't overlap:

1234, 1243, 1342, 1324, 2341, 3412, 4321, 3214, and so on.
but never 1111, 1112, 3333 or 3242.

To find out how exactly it works, I tried to delete some lines, tweak the numbers. The result of that is either numbers change to repeats, all zeros or a logical error. The following is the code placed in the module and can be used for other forms and in this case it is used for the labels in form1 windows form:

Sub Shuffle()
Dim a(4), i, j, RN As Integer
Dim flag As Boolean

Shuffle 10 Audio Files And Play In A Loop?

Dec 11, 2010

I have 1-10 audio files that were selected by the user using an "openFileDialog" (with a button and textbox for each). Now, I want it to play all of the files that they selected in a random order when the user clicks "Button12." After all the files have been played, I want it to start over and play all of them in a random order again. I don't want it to stop until the user clicks "Button13." When the user clicks "Button 12" again, it should start playing them in a random order again.

VS 2010 Shuffle Up And Deal Program Would Like Advice?

Nov 10, 2011

I have handed this assignment in and it works albeit not in the most elegant way. I am taking my second programming class ever and I would love for some feedback and answers to a few questions i have. First, what would be a better way to display the correct image to the corresponding card. Using all those if statements seems ridiculous, but i cant see a way around having card 1 possibly equal each value from every suit, card 2 equal each value from every suit, etc.

Second, my professor wants us to be able to record the seed value so that we could then plug it back in and return the hand that was shown when it was created. i have done this but I am a bit confused. The seed shows up as a value from 0-999, but when you use the combination formula to figure the total possible amount of hands you get over 2.5 million. Since i only have 1000 seed values does that mean that multiple hands might share the same seed value or does that number (0-999) mean something different eache time? Sorry if my explaination seems confusing.

Third, I am always looking for advice on better ways to do things. If anyone has free time and would like to offer constructive critisism I would be grateful.Below is the code. I only left in picturebox display for 1 suit so as to shorten the total amount shown. I also removed code for other buttons and stuff.

Public Class Form1
Private Sub btnShuffle_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShuffle.Click
' Variable Declarations
Dim intSuit As Integer ' Row
Dim intCardValue As Integer ' Column

Audio Playback - Make The Shuffle Never Play The Same Song Twice

Mar 21, 2011

Basically my program has a "shuffle" music feature:

vb For i = 0 To 26 num = randomObject.Next(0, 27) My.Computer.Audio.Play("C:UsersMcturtlesMusicSongs" & num & ".wav", AudioPlayMode.BackgroundLoop) Next

Which selects a random number 0 - 26 and selects the corresponding song.

And a straight play feature:

vb Dim counter As Integer Do Until counter > 26 My.Computer.Audio.Play("C:usersmcturtlesmusicsongs" & counter & ".wav", AudioPlayMode.WaitToComplete) counter += 1 Loop

All of these activated by a button(separate for each)

When I click one, it makes the program stop responding. I'm pretty sure it is the .WaitToComplete mode, but I can't find a way to make it continuously play without it. If you can find my error. Also if you could tell me a way to make the shuffle never play the same song twice, that would be awesome as well.

I have a question about working with arrays

I don't have any code written out I just want to know the best way to do this sort of senario to put into a flowchart, the program i'm working on isn't homework, its just practice and the book I have is less than helpful with what i'm working on.

I want to check to see if at least 3 numbers in the array are the same but no less so that it meets a certain requirement how would I check this?

Numbers Change When Put Into An Array?

Jun 2, 2011

I have a datagrid in my form and numbers are input it. I then loaded one of the columns into an array. This is the piece of my code that loads the array:

Me.dgv.CurrentCell = dgv(1, 0)
For i = 0 To (Me.dgv.RowCount - 1)
Receipts(i) = Convert.ToSingle(dgv(1, i).Value)
Next i

The first value is -2912895.29. I put the program in break-mode and it keeps loading the first value as -2912895.25. I checked and it loads all of the values a few cents off.

Array - Randomly Generate Numbers

Apr 14, 2010

I am making an application that randomly generates numbers. I then have to find out if those numbers are even or odd. Then place them in the corresponding array ( EvenNumbers() or OddNumbers() ). Then display the random numbers array then the even and odd numbers array. I am up to the point where I have the generated numbers and can tell if they are even or odd, but can't get them into an array. I am trying to do it like this....

Replacing Repeating Numbers In An Array?

Nov 11, 2009

I have an array that hold 6 random number, then this numbers are sorted from smallest to highest. My question is: How would I go about replacing any repeating numbers with a different random number. I.e. 1 3 7 2 2 9 is sorted into 1 2 2 3 7 9, but I would like to see one of the 2's replaces with a different number (that it is not currently in the array).

I have no code for this part - but the code for making the random number, storing them and sorting them works fine.

Setting Numbers In Array And For Loops

Sep 27, 2009

What I'm trying to do is: Set numbers (0-51, a deck of cards) in an array like card(0) = 23 (Which would represent, say, the Jack of Clubs). Then card(1) = 35. Now I have two arrays.

The first array is what I have mentioned above.
The second array is holding a Boolean value. So what I do is make a loop going through the card() array from 0-51. In this loop it generates a random number between 0 and 51. Then I check the second array (iCardUsed()) to see if it holds the random number.

So iRndNum = 13 (Say 13 was the random number)
loops through the second array checking if the there is a value of 13. If there isn't then I want it to set card(whatever it was on, say 12) = 13. then make iCardUsed(13) = true saying card 13 was true. I'm not too sure what to do if it was true, not false.

Alright, now that I explained what I was trying to accomplish, I'll post some code and the project.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim iCard(0 To 51) As Integer
Dim iCardUsed(0 To 51) As Boolean
Dim iValue As Integer
[Code] .....

Now, this works, but there are some duplicates in the array. I'm not sure why there would be duplicates. It worked fine when I manually entered data so the logic of it is right. [URL].

Calculating The Modal Average Of An Array Of Numbers

Nov 6, 2010

OK, so I've been given an assignment due for Monday, which was to create a console program which allows the user to enter an unknown quantity of numbers, then have the Mean, Median and Mode averages displayed of said group of numbers.

So far I've managed to get the Mean and Median to work, for both odd and even quantities of variables. I am however stuck on getting it to calculate the modal average! I don't really know how to approach this, would a structure with two fields, variable and quantity of variable, work?

Below is the code, I haven't made it display discrete of continuous data yet, I'm leaving that for the end.
