Reading And Writing A Text File That Is Saved As A Resource?
Jun 17, 2010
I would like to know how to write to a text file that is added to resources and then have it show the contents in a text box.But I would like to have it on a timer so every second it will refresh as I am trying to make an instant chat program.Also I would like to note that I want it to delete everything after all the users have closed the program. Is there any way to make it so the text file is empty when there is no body using the program any more?

How would a person read a line of a text file by the number of the line. In other words, if I wanted to get the 3rd line of the file, how could I store that third line in a variable. While I'm at it, I might as well also ask how to do the opposite, or write text to a specific line (in this case, writing over the other information on the chosen line).

I'm using visual basic 2008 express to do some simple stuff. For this project, Im reading in one large text file.The top of each page has a header section that is always the same, except sometimes a dept# changes, signifying a new set of data.The first line always has the text "RunDate", so when I read that, I know that I'm at the top of the first page.After reading the first line, I'd like to immediately go to the sixth line and grab that dept# and store it.dept = left(trim(myline,7)(Its always 7 characters long) so I know what dept I'm working on.I'll then loop through and write each line to a new text file, until I hit the top of a new page.At that point I need to look at line 6 again. if the dept # is the same, I'll keep writing to the same file.Reading and re-writing from the text files is easy, I just loop through line by line, but I need to be able to jump down to the 6th line, and I don't know how to do that without reading each line to that point"

The program that I am writing has three default variables that I would like it to store and also be able to change. I have them in a text file called "settings.txt" The format of the text file is as follows:
Default Source "I:DCIM101MSDCF"
Default Destination "C:Documents and SettingsChristyMy DocumentsMy Pictures"
Default Backup Destination "D:My DocumentsBackupMy Pictures"
The field descriptions eg "Default Source" take up 30 characters, so the variable data starts with character 30. I know their has to be an easy way just to pull out the data from a particular line starting with character 30 but I can't find it.

I'm writing a program where there are text boxes and the user can enter info and append them to a text file as well as read from the text file and view the various entries in it. The problems I'm running into are that I have a button that opens an open file dialog box allowing you to select the file, and I want to get it to open the first entry of that file in the correct text boxes. the code so far looks like this
code:
I used to have this bit of code in there but there was a conflict with the .txt file being used more than once at the same time while it was in there.
code:
Im also having trouble writing to the file and I'm not sure why. I have an "Append" button that has this code in it
code:
and it comes up with the issue "object reference not set to to an object instance".

Their is a problem whenever I want to write something to a text file. Please see the attatchement to see what happens when I'm debugging. I've put the code for writing to file right at the end of the program.Here is some of the code which shows how the program writes to and reads from the file:
Option Explicit On
'Force all variables to be declared.

I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?

(First off all hi to everyone my first post!) Ok, i have two programs one program writes to a text file on a consistent basis, while the second program is opening this text file on a consistent basis for reading.. Sometimes the programs are accessing the file at the same time and the user keeps getting this error : this process cannot access the file because its already in use..
Is there any class, in system.io that i can use to modify the settings of this text file so both programs can access it at the same time?

Even a primer on just reading/writing to a text file would be golden. The array confuses me further, but understanding the data is primary.
Basically, we're writing a program to manage inventory for a bar. Fields and a few lines are below. The delimiter is "||"
So... How do we read the data into the arrays? NAME would be strName(), etc for all of them.
how to write and update existing data.
UID||BREWERY||NAME||SIZE||FORMAT||SEASONAL||PRICE||CASECOST||CASEQTY||BREWERYLOCATION||BREWSTYLE||ST YLE||ABV||CLASS

I'm trying to create a program that stores a users stats for their character (for something like an RPG). I know how to write more than one line in a text file, but I want to learn how to read and write text on specific lines of my file. I know that you can just read each new line individually in order using a StreamReader, such as
username.text = readLine.ReadLine()
userage.text = readline.ReadLine()
[Code]....
This is good for just displaying the stats and changing them from a constant interface, but I'm afraid that eventually I'll need to read/write specific lines, like reading the fourth line which might specify magic level, or writing a new money amount.

I have the same problem that Niphoet had in this thread: vb .net overwrite a specific line in a text file
I am trying to implement the code that Axarydax showed in C# that I am trying to translate to use into vb.net. My problem is that the code will make my new text file but will not write any of the lines from the other text file to it and just leaves it blank. I think my problem is with the while loop statement but I am not sure.

I have a text file that is going to store some data in this current project. Instead of having it stored on a location on the PC (like C:Test.txt) - I wanted it to be a .txt resource of the application.Using a streamwriter isn't working when I'm attempting to write to the file. This following code runs without error however when I exit the application and look at the text resource file it remains blank instead of showing "Testing".
Dim Writer As New System.IO.StreamWriter(My.Resource.TXTRESOURCE)
Writer.WriteLine("Testing")
Writer.close()

I am witting an app that will generate batch files to do an unattended installation of a share point 2007 farm. I already have a batch file I use and it's pretty big. I copied and pasted the content into my application, and I'm using the System.IO.StreamWriter to write to the batch file from the winform. [code]As you can probably guess, I'm doing all of this in my mainform code window. There are maybe 3 or 4 batch files that will be generated based on the selections made on the form. For example, I'm generating a batch file to create the OU, Group and service accounts the farm will use in active directory, I'm creating a batch file for all of the variables that will be used for the additional batch files created, etc. How can I split this up? is there a way to create the batch files without having to actually copy, paste my existing batch file content into the mainform code window? I'm using file.writeline on each line of the pasted content by the way.

I have seen a few different ways of Reading/Writing Text files. What i am trying to achieve is a simple debug file in the most efficient way possible. Currently I have....
If System.IO.File.Exists(debugpath) = True Then
Dim Debugwriter As New System.IO.StreamWriter(debugpath, True)
Debugwriter.WriteLine(debugwrite)
Debugwriter.Close()
[code]....
1. Do I have to close and reopen the file each time I want to write to it.
2. In vbscript I would simply open the the file at the start of the script and close at the end is the same possible here.

I have created a small game for my son and after each game it tells him his score.all I want is to write the highscore to a file and have it open each time he begins a game..so he can see what his last score was. I dabbled with all this Io.file stuff and I just can not seem to get it to write to the file..also how do I work with app path in this case? I mean when the game is done and installed the current path of the save text would change.

I have created a code in VB.NET to read data from text files. Data is read from a list of files, where each file is changed using a for loop. Data is written to a new text files. Each file is read one by one and written in the same way. Now, my speed of execution is very slow. I am using a Quadcore processor with only 20-30% of CPU utilization when my code runs. Is there anyway I can increase the speed of reading and writing? To read only 125 files it takes 10 minutes or more, which is very slow indeed, because in the end I need to read thousands of files and write them. Each file is approxiamately 30-50kb.
Here is my code.
Public Sub ReadRMRDataFileIntoTextFiles()
'Read in the customerids once up front
Dim customerids As Collections.Generic.List(Of String)

I'm trying to write a program that will read a text file, and sort of filter out some things into some new files for myself. I have a website that I like to put information such as Artists, and songs for music. My website writes the Artist, and Song I input to one file on a new line in the format of (Artist - Song). The problem is it's gotten massive! I want to start organizing my artists, and songs anyway I come up with but I don't even know where to begin. To narrow it down I want to go into the file grab the artists name before the (-) and then write it to one file. After that I want to write everything after the (-) which is the songs to a different file. What file reading, and writing method should I use? As you might be able to tell I'm quite the noob.
