Read Text Line By Line?
Feb 12, 2010
I have got a RichTextBox1.Text , a timer and a TextBox1.Text. Now I need an idea for timer code. It should on every timer tick read the RichTextBox1 line by line and transfer that line into TextBox1.Text something like TextBox1.Text = RichTextbox... etc
Example (RichTextBox1.Text):
Code:
blablabla
somerandom msg
123 456
now every timer tick the textbox1 should contain line 1 so " blablabla " than line 2 " " somerandom msg " line 3 " 123 456 " etc. untill there is some text. (the text is variable so is the amount of lines and length per line makes it hard to do with Mid function..

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

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.
full code here
-------------
Dim objReader As New System.IO.StreamReader(sOpenFile.Text)
Dim sTextLine As New ArrayList()
Dim sText As String = ""
Dim i As Integer = 0

I have a multiline textbox from which I would like to read each individual line and store it in an array. I don't want to store each carriage return, I want the line itself.I have been using this, but it only records lines followed by carriage returns.
Dim arra() = txtReceipt.Text.Split(Environment.NewLine)
Here is a visual example: [URL]From that top right textbox, I would want arra(0) to be "Type some stuff here (and hit the return and" and arra(1) to be "tab keys...)"

I am trying to read a PDF file line by line using PDFBox.This is the first time I have ever attempted to do this with a PDF so I am not sure what I was expecting but I thought I would end up with some "mark up", which I could use to parse the lines I was looking for out of the file.
Anyway it didn't work out the way I had planned and I am not sure if that is because I am using the wrong tool or not using the right tool correctly.I managed to extract the text but I didn't really see any mark up that would be usefull to parse the file. Does anybody have any experiece with extracting test from PDFs. What tool(s) do you recomend?

I am quite new in VB NET, after VB. and unfortuantely I had to copy paste and merge the code fragments from some tutorials.
I have a folder including 200 eng files which can be opened by notepad. And each file has around 4000 row; with 60 field seperated by coma. I need to read specific row-field value at each files.
Now what I can is:
a) reading individual txt files and find specific value
b) listing all of the files in the folder
c) I can merge (a) and (b) and read all the files automatically, but since ram is continuously increasing, and at one point (sometimes 163, sometimes 169, or 170. files or something) it gives an error as "System.OutOfMemoryException". My ram is 4 GB and when I get this error the ram is increasing to more than 3 GB.
1- Could it be happen because of being eng files instead of regular txt files?[code]...

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.
