Lines In A Text File To Multi-Dimensional Array
Dec 12, 2009I am trying to turn data in a text file seperated by spaces into a 2D array.
It is for a math game. The data is statistics based on the performance of the user. One line looks like this "John Doe 0 0 1 3 0 6 0 22"
I need to put the line into an array and then be able to search by name to display the results. I keep getting extra spaces in the input of the array so the data isnt where it should be. It seems that the first entry works correctly, but appended lines do not enter correctly.

Dim FILE_NAME As String = "C:\Student_Results.txt"

Reading Individual Lines Of A CSV Into A String Array?
Mar 11, 2010It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on.(I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()
[code].....
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array.
VS 2008 Copy One Dimensional Array Into Two Dimensional Array?
Feb 17, 2010I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

Get A Bunch Of Lines From A Text File (they Will Be Filenames Eventually) Which Are Split By New Lines And Puts Each One Into An Array?
Jun 22, 2010I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String

If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.
File I/O And Registry :: Reading Text And Splitting To Arrays Then Echoing To Textboxes
Mar 1, 2010I'm currently making a program that will be used to practice German. It reads from textfiles that have English words (noted by # prefix) and German words (noted by $ prefix). An example of this:
#hello $hallo
#good $gut
#evening $abends
The way it currently works is it loads a text file, finds all # and splits to an array called "English" and finds all $ and splits it to an array called "German" What I want it to now do is feed the "English" entries into textboxes on the left, and "German" onto textboxes on the right so I can then match them out and make a sort of memory game out of it. Unfortunately, I don't know how I would loop an array through multiple textboxes. Conveniently, the textboxes on the left have even numbers, and the ones on the right have odd. Is there a way to possibly find all evenly numbered textboxes and loop "English" array entries into them, and the same for "German"? I've realised this has now gotten a little convoluted, but hopefully somebody understands. I can screenshot the form for better explanation, and copy my existing source code if anybody wants it.

Splitting A String In An Array
Jun 9, 2010I am trying to split a string into array. I know about split, but it seems to need a separator of some type. Suppose I am going to be working with input like the following. 8561369 and I want to split each character of that string into an array. I tried something like this, but again Split seems to need a separator, I just keep getting the entire string in one entry of my array, not split. Dim values as String 'I am going to be populating this string variable via user input eventually, 'which is why I cannot just add spaces. values = "8561369"

Splitting Variables Into An Array?
Jan 9, 2011im already familiar with splitting variables into an array using a certain character e.g.

(1)surname
(2)dob
im wondering whether you can split one variable according to its characters e.g.
strtextfield = name
strpersonarray = strtextfield.split(unsure as to what char)
strpersonarray = (0)n

Splitting String - Separate Each Value And Put In Array
Jun 15, 2009I have the following string:
[URL]
I need to separate each value and put it in an array. typically it would be done by ".split". however I need it to be split in this order: 0, 50, 100, 200, 400 etc.. In other words, I need it to read the rows left to right. I have no problem separating each number, I just need it to read it in the specified order. I've tried the regexp and I forgot to mention that after each line there is a line break. I am not sure if this would impact the regex, but in any case, after i do the regex, I get the following order: 0, 6.65, 84..??, 35.... etc
I am not getting the order I need as stated above
Expected results: 0, 50, 100, 100, 200, 400, 218, 9.8, ???, 6.65, 6.31 etc...
I am going to follow some of the suggestions below by splitting up the string into separate lines initially. this code almost does that:
Dim fields() As String
fields = calculationText.Split(vbCrLf)
Unfortunately for some reason the spaces are lost. When i look into the array, all the spaces between numbers are lost. why?????????
Splitting String With Array Of Char
Jun 14, 2011I want to split a string with this array of char
Dim sepa As String = " '"",.;:(){}[]·#|-_<>+¿?=/&%$‚¬@!¡"
The question is how do I include in this string vbcrlf? So I can do the fallowing:
dim palabras as String() = RichTextBox1.Text.ToString().Split(sepa)
I tried:
Dim sepa As String = " '"",.;:(){}[]·#|-_<>+¿?=/&%$‚¬@!¡\r\n"
But it does not work.
Splitting Text From A TextBox Into An Array?

RegEx - Splitting First Parameter Into Array Of SubStrings
Sep 25, 2010I am a little bit confused by the following VB statement
commands = Regex.Split(script, _
"GO", _
RegexOptions.IgnoreCase)
I know what regex.split does. I know what the first parameter is. The second parameter is what I'm confused by. I think it is using the word "go" as a delimiter to split the first parameter into an array of substrings. But I don't understand what that refers to.
Splitting A CSV File Line Array Using Regex
Jan 5, 2011I used to do a bit of coding in early versions of VB years ago but moved on to things like RPG400, CL and SQL on an AS/400 box. As I am no longer in this career, I havent touched an AS/400 for a while either.
I am currently working on a visual basic console application in Visual Studio 2005 which takes various csv files from an osCommerce web shop, processes them and writes the data to TAS Books accounts software with the aid of the Infoplex COM module.
I have 2 functions, one reads each line of a csv file into an array, and the second function uses Regex to split the lines array into the various fields before they are added to a structure.
There are something like 5000 records (lines) in the csv file, one example is as follows;
[Code]...
My problem is that due to the formatting of the product description in the example csv line above, it fails the Regex match and therefore fails to read.
I know this is because my pattern is wrong, but I'm not sure how to solve it, I think all I really need is for Regex to split the line by the "," between each element, this might be a little difficult because some of the descriptions contain both , and " but never one after the other.
Splitting A String, Adding It To An Array, But What If Isnull?

As so, but what if i miss a day? Or i dont always work saturdays sundays. from the code below you will see i have not added any work around fora null value. My suggestion is to incorporate a <nw> (no work) tag, but the code needs to change <nw> to my own personal message that i choose.

Splitting Delimited Text File Into Array And Variables
Nov 16, 2009I have a delimited text file, let's call it models.txt and it's delimited by a comma with carriage returns.
example:
21,Z920081
22,Z920082
59,Z930023
120,Z930027
I'm trying to input this into an array and then a combo box using:
dim item as integer
dim array() as string
dim ifile as integer
[CODE]............
What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.
