Check To See If At Least 3 Numbers In The Array Are The Same?
Feb 8, 2009
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?

I have a textbox, with the following items anim,welcome,30anim,items,20 I am using rhe following code to read each line in the textbox Dim MySplit() As StringDim MyLine() As StringMyLine = Split(tags.Text, vbCrLf)' Split the Contents of the tags TextBox at the Line SeparatorsFor Each mLine As String In MyLineMySplit = mLine.Split(","c)anim_time = MySplit(2)Next The code works fine forward, it sets the variable anim_time to its correct value. What I want to do is to make it check for similar numbers one item backwards. For example: anim,welcome,20anim,items,20 Here the two anim_time as equal. I want to warn the user that this is happening.

Then endif I want to be able to check inside the string to see if it only has number, if it does only contain numbers then run whatever is inside the if statment? What check do i use to check if the string only contains numeric and no alpha ot () etc ..? What i am trying to check for is mobile numbers, so 077 234 211 should be accepted, but other alphas should not be

I have a working piece of code that checks that 4 out of 5 random numbers are in sequence. The numbers correspond to 5 dice rolls. I'm trying to learn VB and I think the code can be improved since it's so cumbersome. The sub checks to see if any of the numbers are duplicated and reassigns one of the duplicates to an arbitrary "11" which is outside of the 1-6 range of a single dice roll. Then the values are inserted in an array and sorted and the sequence check takes place. score of 30 is assigned if 4 of 5 of the (sorted) numbers are in order. If not in order, a score of 0 is set.
Code follows:
Private Sub OtherScores4()
'Check if any of the rolls are duplicated and reset one of the die to arbitrary "11".
If Dice1 = Dice2 Then
Dice1 = 11
End If
If Dice1 = Dice3 Then
Dice1 = 11

I need some kind of code to check if the first line in a richtextbox contains numbers or not.
Something like this:
If Richtextbot1.Lines(0) contains Numbers Then
Goto startbot
Else
[Code].....
If the first line contains 4 or more numbers, it will use it. After each loop it will delete line 1. So it repeats for the next line. When my code reaches the 3rd line, and it doesnt find 4 or more numbers it needs to delete the line.

I am working on an application that llops through a dataset. Within each loop, I need to test to see if the datarow number is contained within an array. For example:For Each Page in Pages Test to see if page number is found in array (i.e. page number = 3, array = 1, 3, 4, 7, 8)Next Page The test would match on record numbers 1, 3, 4, 7, 8.

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.

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

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....

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

I have not messed with VB much and I have been trying to do something that has me stumped. I wanted to create an array of 10 random numbers. Each of these numbers then is printed onto a label. From here I have two more labels that show the highest and lowest value. I got the first part, 10 random numbers show up but then things get shaky. This is what I have thus far.

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.

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].
