Loop Causes Duplicates In String
Aug 21, 2009
I have for-next loop that loops 6 times around before exiting. Each time it loops it adds a small number and a space to a string so I end up with a string containing 6 numbers separated by spaces. Whats ends up happening is I get "555 555 666 666 777 777" when I should get "444 555 666 777 888 999". I know for sure it isn't the code that generates or applies the numbers because when you put a messagebox.show at the end of the loop it works perfectly, so it seems to me something is happening to quickly but showing the message box every loop gives it time to catch up. What can I do here?

I'd like to create a loop that dupliates a label I've made and put it all over the screen. Example of what it would look like.
[Code]...
I can do that in Flash/Actionscript but dunno how to do it in VB and I can't find it anywhere.

I am trying to find duplicates in a string. The code works more than I would. The purpose is to create a jagged array with values and positions like this one:
myString = "1123464263948465475965069068547363532627281901"
jagged= {{{1},{0,1,42,45}},{{2},{2,7,36,38,40}},{{3},{3,9,31,33,35}},{{4},{4,6,11,13,16,29}},.........}
Value Positions
1 0,1,42,45
2 2,7,36,38,40
3 3,9,31,33,35
4 4,6,11,13,16,29 ......... and so on with unique keys and multiple or not values.
My code do this, but looping all over the string there a moment when it repeats values and positions, because already found them earlier. How do I make to keep just the UNIQUES? How do I skip the loop when the value is already in?
My code below
Public Class Form1
Public myString As String = " "
Public jagged()() As Integer
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
myString = "1123464263948465475965069068547363532627281901"
jagged = New Integer(myString.Length - 1)() {}

I want to remove duplicate values from a string using VB.NET. If values = "3,40,15,109,15" then I need the end result to be "3,40,15,109". I'm using the code below but receiving the error message 'Value of type 'String' cannot be converted to '1-dimensional array of String' and I'm not sure how to proceed.
Dim values As String
values = lblIDList.Text
'Remove duplicates
values = RemoveDuplicates(values)
[code]....
Value of type 'String' cannot be converted to '1-dimensional array of String'.

I have a string array Array1 and a string array A2. I want to combine these in a 3rd array A3 but excluding duplicate values. Can this be done through lambda expressions or only through iterating through the array and checking array.Contains()?

Okay so i have a very large list of string (500 000 strings) i want to check the number of duplicate strings and maybe even isolate the duplicate strings if i can.
i cant find a fast method to do so :S
i tried using a string array (slower than list) takes ~15mins
i tried using list with the code below takes ~10 mins
that wont cut it :S i need something faster.

I have a somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Is it possible to create a loop using a string I am writing a program and I need it to output 3 letters ahead of the letter you input for instance if you input a then it outputs d and if you input u it outputs x, and also the same with capital letters A then D U then X and so on. I have writted the program the only problem is that when I input X I want it to output A but it outputs [ instead I need to create a loop where when I input X it starts the alphabet over again, and I need to know if it possible and if so how will I go about doing so.

I have a string where I have created a template so to speak.
{
Dim myvariable as string
Richtextbox1.text = Richtextbox1.text & "The dog jumped over the" & myvariable & "to find the fox."
}
I have a list box that contains a list of options that loads into the variable example: fence, bucket, etc.
So the sentences would read like
The dog jumped over the fence to find the fox The dog jumped over the bucket to find the fox
Right now I have it coded to display into a rich text box but everything is in the same rich text box.
I'm trying to load the string into an array at the end of each loop this way I can then have each sentence separated.

for i = 0 as integer to 100
result &= "Name" & sqldr("name")
result &= "Lastname" & sqldr("lastname")
result &= "dob" & sqldr("dob")
next
The sqldr is the sql datareader (not important here)
I want my end result to be
Name1 = Sam
Lastname1 = Davis
dob1 = 01/01/1966
Name2 =

Name3 =
And so on depending on how manyrecords are in database. How do I make this happen in this for loop?

I have a string which can be of any length. I want to loop tthrough this string and if there 53 characters assign that to Variable1, then loop round again and assign the next 53 characters or less to variable2 etc etc until the end of the string. Ideally I would not want to split words - but that is another problem.....

Basically what happens is each time it loops through it adds a number to the end of the string, and by the end I should end up with an array full of string in a format like "111 222 333 444 555 666" but I end up getting strings like this "111 111 222 222 333 333". The weird thing is, if I add a message box in every loop it works fine, but obviously I don't want a message box pooping up every time it loops through. What is causing this and how might I fix it
The code is:
For x As Integer = 0 To (NumCards.Value - 1)
NumRep = 0
