Mar 18, 2011

I have a text file which contains some data as follows

1, 0,0,0,0,0,0,-288.000,-288.000,-16.200,0,0
2, 0,0,0,0,0,0,-432.000,-288.000,-16.200,0,0
3, 0,0,0,0,0,0,-360.000,-360.000,-16.200,0,0
4, 0,0,0,0,0,0,-288.000,-432.000,-16.200,0,0

There r 7 numbers in each row and need to read each of that and store it as an integer value ...I tried the following code..

Imports System

Imports System.IO

Imports System.Collections[code].....

This works and is showing each number by number ...But is there a way to store each number to another variable...something like a(1)=1, b(1)=0...., a(2)=2, b(2)=0......

FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text

Dec 19, 2008

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?

In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:

Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine

[CODE]...

However, I can't find any methods that will allow me to do this.

Take A Section Of The Xml File And Pass It As A Variable To Another Function?

Jun 5, 2012

I am using XML literals to parse files that contain data. I was wondering if there is a way to take a section of the xml file and pass it as a variable to another function...

<XML>
<DATA>
<STUFF>
<blahblah>sdfsdf</blahblah>

[code].....

I know with XML literals I can use ...<STUFF> and get the info out of that section, but how can I take an entire section of the xml, like MORESTUFF and set it as a variable to pass to another function that can parse that xml?

VS 2008 Reading Text File Line By Line - Put Into Text Boxes

Sep 21, 2009

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.

Reading Text File Line By Line, With Resetting Position To Beginning Of File

Jun 23, 2011

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.

I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.

I've seen other examples, where it works, but you must open it a different way -- with a file number.

Imports System.IO
Dim I as Integer
Dim LineText as String

Let's say I only want line 4..Can I Copy an entire line of text just by searching a text file for a string, such as swf?**For example: I want to get a line of text saying http://mywebsite.com/myflash.swf, just by knowing the .swf extension.

Reading In More Than One Variable From Each Line In A File?

Mar 1, 2010

Trying to read in three variables per line from a text file that looks similar to the first code segment. What we've been taught so far to read in is something similar to the second segment. And it works all and good for single words per line.

If this was C++ I'm pretty sure I could getline and use the comma as a terminator, but I'm not sure if a similar function exists for VB.

Comparing Text File Records Line By Line?

May 14, 2009

I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

Search A Text File Line By Line - VB08

Apr 8, 2010

I just joined this forum as I've been looking for a nice and serious VB forum for a long time

I'm having troubles making a program to search a text file line by line for a specific string.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")

[Code]...

as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.

now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost

for a "Readnextline" command or something like that?

VS 2008 How To Read Text File Line By Line

Sep 19, 2010

Ok, I saw this code on the net

Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)

[Code]...

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

Retain TextBox Line Breaks In Winforms After Assigning Text To A String Variable?

Oct 3, 2011

I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!)

Reading A Specific Line From A Text File And Displaying It In Individual Text Boxes?

Feb 16, 2010

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.

(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this

If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....

And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
