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 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(",")
How can you make streamreader to split a line into two and place it on two different places of the form and how can you use streamwriter to delete/alter file contents.
View 4 RepliesThe problem I'm having is I'm not sure how to go about getting the correct ones into the correct arrays. The data is scattered throughout the file. They are not on the same line and some are multiple on a line as well as blank lines, however they are in pairs. As they are not separated by commas or just white space is there a way to load the first string to the first array and every other string to the second array

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 #

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?
Dim connString As String = "Data Source=" & pDataBase
conn = New SqlCeConnection(connString)
Dim strQuery As String = ""[code]......
I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.

I am trying to split a string but unable to do so.
Dim fields() as string = line.split(",")
The sample two lines of data is as follows
4,"ABCD",6,"FGHI,JKLM",4515,"4512"
7,"ABCD",7,"FGHI,JKLM,NOV",4515."4513"
actual number of columns are six(06), but it is returing seven (07) from fist line and eight (08) from other line.
I'm trying to get split to work.Here is my code
Public Sub CheckUpdate(ByVal FileURL As String)
Dim instance As WebClient = New WebClient
Dim ApplyTo As String = instance.DownloadString(FileURL)
asd = ApplyTo.Split(",")
End Sub
I use it like this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
NewUpdate.CheckUpdate("version.txt")
Label1.Text = NewUpdate.asd(0)
End Sub
(yeah I know i use it on local txt for now!)So with asd(0) it reads the whole file. If i check asd(1) I get IndexOutOfRange . So how does Split() work?

I have an array with about 10 items in it. In order to get the desired functionality I need to append some text to each item in the array in order to sort it properly. Once it is sorted I want to remove the text I added and then just display the second half of each item in the array. The sort works great, but the split function is not worrk.

So basically theres a list box of co-ordinator IDs and a list box of the positions they are in. On another form there is a combo box with the list of ID's that is transferred from the list box on the processing form. I want to display the Position of the Co-ordinator when their ID is selected. How do I match the positions up so when an ID is selected in the combo box their position will appear?
How can i send arrays to a function?
example i have an array with 400 elements containing random numbers how can i send those to a function, say to add 1 to each them?
I have an array of integers and I want to pass the array to a function that will add up the elements of the array and return the cumulative total of the elements of the array. So, if the array contains the values {1,2,3,4,5} the return value from the function would be 15.

In total, the model has 12 parameters and 2 constants used in it, so I figured it would be a good idea to store the parameters in 2 separate arrays - one containing 6 parameters which have to be entered by the user and another one with another 6 parameters which should only be changed in a settings kind of window for tweaking (they are set to default values provided by the model).[code]...

Using the Split function, I can get any part of the array between the delimiters (""), but what I'm trying to do is get all the information after the LAST delimiter in the string.
My program uses parameters from the calling program in this format
parameter1/parameter2/parameter3
parameter2 is a datafile path which may sometimes have a space like :
C:Program Files est company
I did this as a work around
Sub Main(ByVal Args() As String)
dim cArgs as string=""
Dim J As Integer
For J = 0 To Args.Length - 1
cArgs = cArgs & " " & Args(J)
Next
And then used the string split function. Is there a proper way to work with spaces?

I have several parameters consisting of separate System.Byte() arrays. What I need is the syntax for a function declaration where the parameter is an array of arrays - I do not want to delve into System.Collections, and it's my preference not to CType each array into an Object and then back into a Byte().
Problem I'm having here is that:
Public Function MyFunc(arrayparam() As System.Byte) As System.Byte()
accepts a single-dimensional Array of individual Bytes.
Then Public Function MyFunc(arrayparam() As System.Byte()) As System.Byte()

Expected Results: A scalar result of the comparison between Array1 and Array2 such that when Array1>Array2 it is true. See expected array above.
Actual Results: When Result(x) is true, all elements become Array1(x) and Array2(x) .What is wrong with the function?
