a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

I have a text file with an unknown number of lines. I want to read this file line by line and send each line's text in a check list box. But how am i gonna do that when i don't know how many lines exist in text the file? [code]The code above reads only the first line. I tried to do it as in vb6 using while not eof(but here i don't know what to write cause my file isn't opened in a certain channel).
View 4 RepliesI have code that reads the whole file, not line by line.
Here is the code:
FileOpen(1, filename, OpenMode.Input)
Do While Not EOF(1)
datatodisplay = LineInput(1)
Loop
FileClose(1)
I would like to know how I can read the file line by line and then add all results into an array list.

1. Writing the last line of .txt into textbox1
2. Adding line from textbox to .txt
I am working on a functionality which requires me to copy the last line of a richtextbox into a textbox, then removing certain characters. The code I am trying is below. I have on a form a richtextbox (txtMain), 2 textboxes (TextBox1, TextBox2), and a button (button1). The first time a ran it, it worked perfectly - it selected the last line, copied, pasted it into TextBox1. Then after that first time it didn't do it. Perhaps there is a simpler way to get this last line consistently into the TextBox1. Here's the code. (See below the code for a copy of the text in"Text.txt" file):
[Code]...
lets say i make a keyword like eg create file then next to it i quote a string like brain.txt. how would i tel the textbox to get the richtext box line with that keyword then list the keyword add quoted string plus the line number into a listbox?
View 1 RepliesI'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.
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 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 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.

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")

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?
I have a list of random numbers in my text file.I read it like this.

Ok, I saw this code on the net

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
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?
