Arrays - Looping Through A Split String / Replacing?
Jun 1, 2012
I'm trying to make a function in VB.net that will loop through an algorithm. I've split the algorithm into an array using the Split command, so I have an array with the values. I then try to loop through them and replace a # with "Number" where necessary, however VB.net throws an error. Algorithms are in the format A B C D E F 1 2 3 #
Function generate(ByVal alg As String)
Dim algSplit As String() = alg.Split(" ")
For Each digit In algSplit

Okay, here is the problem. I am using two strings, they are separated by a comma and a space. Here is the example: Original String: "David, Narkisim" New String: "Narkisim, David" What I wanna do is have to scan if the original string has the same strings as the new strings. When I load the code, it replaces David, but not Narkisim. Here is the code. It is supposed to return an empty string in the end, but it doesn't.

Is it possible to replace string characters using the delimiter and limit of a split function?
For example you have this string "1,1,1,1,1"
I wish to replace sentence number 2 into the string "2" between the "," character so that will be limit number 1.
So the result would be "1,2,1,1,1".

Is it possible to compare 2 arrays without looping? For this example, I need to compare aryFi.Count to currentarraycount. if aryFI.count>currentarraycount, then I need to add the ones in aryFi.count into a public array named pgarraylist. Since aryFi contains more items, I can't just take the .count-the difference in counts, I need a way to get the items contained in aryFi but not in currentarraycount. EDIT - currentarray is the list of currentarraycount Sounds confusing - but here's an example.
Public pgarraylist As New ArrayList
Dim aryFi As IO.FileInfo() = di.GetFiles("*.xls")
cntdif = aryFi.Count - currentarraycount 'currentarraycount is updated after changes occur and when loading program.
For y = cntdif To 1 Step -1

I am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.

I had a question regarding the split function used in Visual Basic. As of now I have written a function that brings in a string value. The string value returned will probably look like this "List1;List2; Field1,Field2". My goal is to use the split function for this string to put all the lists in one array and to put the fields in another array.
The problem is between where List2 and Field1 are. I don't want Field1 to be placed in the list array. I'm thinking there might be a way to do this by parsing but I'm not sure. Here is my current code below.
Dim s As String = GetSetting("ReOrderList", properties.SiteId)
Dim affectedLists() As String = s.Split(";")
Dim affectedFields() As String = s.Split(",")

I am working on a project and I need to read information from a streamreader and put into an array and then use the split function to split the the lines read by the commas.
Example: Texas, USA, 123
And I need to split the three into separate arrays and then swap Texas and USA to make it USA, Texas, 123. I am using VB.net language and line.split(",") is not working.

I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions
Imports System.Xml.Serialization
Public Class emote

I am trimming some strings but I am unable to do anything about the strings containing plus signs. For example if I have this string with a telephone number
Dim str As String = "+46765124246"
And try
str.replace("+46", "0")
Nothing changes in the string.

I have an issue, i have a program im working on, that i have been working on and im trying to replace a whole block of text. I do it in one spot in my code and it works great, but in a different part of my code, even though im using the same exact logic and pretty much the same code (other than slight variable changes) it will not work, and i have no idea why, it just like ignores it. I took some screenshots:If you look hard the only difference is the "S12000" (top pic) is changed to "S6000" (bottom pic). The pic shows this part about 3/4 of the way thru it.

I'm trying to split a Yahoo historical stock price csv file, downloaded into a string, by what looks like a space character. I want a new row for each split. The split function works for other characters I see in the string. I suspect the characters may be a non breaking space character but I've been unable to split on them. This is the test csv file that is downloaded into the string: [URL] I'm trying to split the string like this:

i have an array that contains a-z.When i enter text like "ab" into a textbox and click the button, it will search the array and replace the text accordingly to the index number of the array and rewrite into the textbox with the index number.
But what i got from the code below is "ab0 1".May i know how to do so that the textbox will only display the index number and not with the letters. Also, how do i search the array from index 12 onwards to the end of the array.
For Each b As String In TextBox2.Text
If abc.Contains(b) Then
Dim ab As Integer = Array.IndexOf(abc, b)

Below is the section I'm having trouble with at the moment:
Friend Sub glbHooks_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) Handles glbHooks.KeyPress
newStr = newStr & LCase(e.KeyChar)
[Code]....
Neither of these worked, though the 2nd one would clean up my code a bit. Unfortunately I'm getting an "Expression expected" error on that "newStr = If..." line. I know there's supposed to be a "Then" somewhere along it but I don't know where it's supposed to be and the poster hasn't gotten back to me on that yet.

What I basically have is a small game which I want to count wins/loss/ties. I have no problem with the game aspect but need to know how I can replace a string in a csv file. IE: If Jim wins the game, his 5 needs to be turned to a 6. After googling quite a while I came across the replace() function, but it doesn't actually rewrite it back to the text file
