VS 2008 Reading RichTextBox Line By Line - Splitting It?
Jun 16, 2009
To read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
I am trying to read in a TextBox line by line and take the first 7 characters of each line and output everything in another TextBox.This is what I have so far.
Dim line, lines() As String lines = TextBox1.Text.Split(Environment.NewLine) Dim i As Integer = 0
Is there an easy way to consume xml to access any of the nodes directly without reading line by line?Here is a sample set of the xml working with. It contains two records of data. I am trying to find a way to load it so if I wanted to get say PostalCode and say Site SID value quickly.
HTML <?xml version="1.0" encoding="utf-8"?><MainSite><MainSites Found="201" Returned="20" Status="0"><Site SID="123456"><Relevance>0.985</Relevance><Title>JDoe</Title><DateModified Date="2010-01-29T01:05:00">1/29/2010</DateModified><DateCreated Date="2010-01-29T01:05:00">1/29/2010</DateCreated><PersonalData><Confidential>0</Confidential><Name><First>John</First><Middle>
How would i go about reading a file Line by Line that within that line The values are delimited by " Example of the data:
"bob" "cat" "1243" "steve" dog" "6789"
I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _ Microsoft.VisualBasic.FileIO.TextFieldParser(My.Application.Info.DirectoryPath & "Records28112011.jd") MyReader.TextFieldType = FileIO.FieldType.Delimited
I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....
i need the app to preview the line in textbox in timeintervalof 1 s (can be change)nd when it will reach to the end it close the text file and andreread it after let say 1 m ..
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim myStream As Stream = Nothing
I have a button which reads a comma separated value file and loads it into a richtextbox. Each line contains comma separated chars.
Once the file is loaded in the richtextbox, i want to be able to select specific values from each line and store them into an array.
For example: Line1: a,b,c,d,e
I want to be able to place only the values "b" and "c" into an array.
I was thinking something like creating a menu for the richtextbox which will be triggered on right click, then highlight the values I want, press right click and select 'place these values in an array'.
it doesn't have to be the way i proposed it, but it definitely must use a richtextbox.
The following code selects a line ina richtextbox. It works OK expect from one problem:
When a line is biger than the size of the richtextbox, it wraps it. This create a big problem as I can not select the last line of the richtextbox (when a line is wrapped it becomes two lines). When I set wordwrap to off it works just fine
Private Sub RichTextBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseMove
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
I'm having trouble with reading a .txt file line by line, converting it into a string, then putting it into a listbox. When I execute I get an error saying "IndexOutOfRangeException was unhandled" Here is my
I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio
I have a text file with thousands of entries of 11 digit numbers. With a button click I need to import the data into my form in a texybox, read the first entry, run an algorithm and place the result as a new line in another textbox. Then move to the second entry and so on.
I am able to read the data from the file and place into a textbox but I am having trouble with reading each entry line by line and running the algorithm.The algorithm that needs to be ran consists of reading each character one at a time for each line and is as follows:
ENTRY example: 12358458754
The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first character and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of the "odds" which were summed then multiplied by 3.The total result needs to then be divided by 10 and the remainder needs to be subtracted from 10. It should be something like this: (10 - ((sumOdds * 3) + sumEvens) mod 10))
I must use streamreader to read text file line by line into array.
Here's what I've got.
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click Dim numbers() As Double = New StreamReader(txtfile.Text) Dim numbersarray() As Double
the following code was to be entered to read each line of the file "line by line" It did not work for me as instructed and I am trying to understand why?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim FILE_NAME As String = "C:UsersOwnerDocuments est.txt" Dim objReader As New System.IO.StreamReader(FILE_NAME) Dim TextLine As String

I'm storing a multi-line text file (in .dir format) in the directory the user chooses, and what I need to do, is when they import it (which my program can already do) I need it to find the end of the file (line) and then read that line, that line will be a number which corresponds with a number system. Basically, the file looks like this
1. Time: 10/27/2009 4:58:09 PM Title: Title Author: Author Entry: Test
2The 2 at the end specifies what the number will be next time. How do I do this?
I have a data file which I am de-compressing and then reading line by line.This includes data which is then read by my function which is split into sperate bits then inserted into a database.My reader is currently taking ages. (largest file being 1.8GB)I am using:
Code: ' File exists, read file. Dim objReader As New System.IO.StreamReader(fileName)[code]....
Is there a quicker way to do this? And possibly a progress bar to show how far it is through the file?

And so on, each line in the textfile will consist of two words seperated by a = Now I want to load this textfile and then be able to use each line and have a name for the word on either side of the = and then do something with line 1 word 1 and then do something with line 1 word 2 (word 1 beeing the first word before the = and two beeing the one after the =)
I have a richtextbox that I import 20 rows of data into. I apply a rule to the textbox that reads to identify keywords:
