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 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....

Basically, I'm creating an application which takes a list of words in .txt format, such like this:
Abc
Def
Ghi
Jkl
mno
What I want to be able to do is modify the words, one by one, so that I end with
Abc1
Def1
Ghi1
Jkl1
mno1
or whatever the user wants.
I created this app in C++ to get the logic, since I am more confident with that

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))

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'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?

Is there a quicker way to do this? And possibly a progress bar to show how far it is through the file?

For example I have a strint containing text with more than 1 line. For example:
"Hello How Are You"
I want to read a specific line of the string, if I choose to read line 1 of the string in a messagebox then the word "How" will probably pop up.

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.

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 making a function that is supposed to delete a line from a textfile "test.txt". I'm having no problems with finding what line i want to delete. The basic idea is this: read the whole file with streamreaderdelete the linerewrite the file with streamwriter. My problem is the last, how can i completely remove the file content, and write another string in it, writer.writeline just appends a line.

I am having trouble removing a line from a text file. When I click on the button in order to remove the line it gives me an error that access to the file is not possible. Now I assume that the file is in use during me wanting to change it and therefore cant save it while it is loaded in ht application. I have tried a few things but cant seem to get it to work.Essentially what it does is that I have another dialog that a used can add data, the data is then written to the file FilingLocations.txt and then it saves it and loads it again. But once the line is no longer needed I would like to have the option to remove the line agaise.
Here is the code:
Private Sub cmdRemoveLocation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemoveLocation.Click

I have a program that reads a text file tab delimted using OLEDb I need to be able to allow the user to insert a user created record into the file which I can do. The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record?
Dim strDelimiter As String = vbTab
OpenFileDialog1.InitialDirectory = "C:\"
OpenFileDialog1.Filter = "Text Files (*.txt)|*.txt"
