VS 2010 Editing Text File Specific Lines?
Feb 13, 2012
I'm new here and I'm trying to make a little program with Visual Basic (2010 Express Edition).The purpose of this program is:
1) Load the text file lines and split them into a constant and a value
2) Edit the text file lines values
The content of the text file is like this:
[Code]...
This basically split every lines in two parts: the constant ("Name", "Surname", "Age", "Hair") and the values ("Mario", "Rossi", "50", "Black").Now about the second point, I've added a Button1 which should take the Textbox1/2.Text and the Combobox1 selected item and replace the values(aka separator(1)) in the text file. The problem is I don't have any idea at the moment how to do it. What method should I use?

I have 2 text files that are formatted in standard XML One of them contains some lines that need to be copied to the other. What i am trying to do is search through the first file until i see the string "<Segment" then copy all lines into a rich text box up until the string "<segment/>" I Then want to look through the other file until i find the string "<Jointfree/>" then copy the contents of the rich text box to underneath the Jointfree String I Also need to search the second file until i find the string "<Markers/>" and then paste some text into the line above the markers tag.

I have a program that will read a text file and put information from the text file into multiple text boxes. What I am trying to do now is be able to change the values in the textboxes and be able to write the specifc changes back to the text file. One way I though of doing that was using a while loop and copy the lines of the text file to another text file, then when it finds the line that has the specific change from the text box, make the change and continue writing the line until it reaches the end of the file. Then I was going to copy the file and overwrite the original, escientally making the change to the new file. Right now it will make the new file but will just make a blank text file. I think the problem is in the while loop statement but I am not sure. Here is the code below:
Code:
Private Sub submitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitButton.Click
Dim trackname As String

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 a windows form with a textbox and a button, what I am trying to do is enter a number in the textbox and when clicked on the button to cut and paste the data in to a new text file (from number 0 to the number I entered).ie, textfile 1 has 100 lines of data, I enter 25 and press OK I would like to take the first 25 lines and save them into a new text file and save the remaining lines in textfile 1 so it should be like textfile1 75 lines and textfile2 25 lines.The closest I've come to this is the following but this only deletes the one line..[code]

I want to create a little program with textboxes in it, that writes the contents of these textboxes to a file. It also needs to write some predefined lines to the files, even on the same line as where the contents of the textbox is.
Heres an example:
The file should look like this when you open it in notepad:
^1::
Send t Text from TextBox {Enter}
First I think I would need to do this:
Dim ioFile As New StreamWriter("scripting.ahk")
ioFile.WriteLine("^1::")
If I do the above it works.. But how can I write another line where the "Send t" and "{Enter}" gets written automaticly before and after the contents from the Textbox?

I have a text file with user names in them on separate lines. I want to check to see if any of the lines doesn't match the exact text im checking for. It doesn't matter what line the text is on, as long as it is in there. If it's not, alert me. Previously i tried .contains() but obviously if a user name is "hello" and another's is "helloworld" it will match both of them.So basically i need to read all the lines in the txt file and if none of them lines contains the specific text im looking for then alert me.

I have the following code to read a csv file and copy each line to another file as long as it does not contain certain strings, it seems to work a little but it leaves some lines in it shouldn't, and it's also taking lines out it shouldn't as if I keep running it again on each output file it eventually takes everything out!
Private Sub Strip_File()
Microsoft.VisualBasic.FileOpen(1, tFile.Text, OpenMode.Input, OpenAccess.Read)
Microsoft.VisualBasic.FileOpen(2, "C:AcmeIPPMaster.csv", OpenMode.Append, OpenAccess.ReadWrite)

As you will see from the code below I need to be able to tell before the array runs how many members of the array there are or else the program will crash. How can I redim the array depending on how many lines are in the text file (RECORDS.txt)

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Okay, so I've been looking on the web for a way to read only ONE line out of a text file. Recently I've gotten by by creating separate text file for each line (such as a text file named, "Username", another named "Password", instead of creating a single text file with both the user name and password.) Now I am faced with having to do this. I want a quick and easy way, VB won't let me do open file as input #1 for some reason. I just need the second line of text out of this text file. What is the quickest and easiest (and painless) way of doing this?

I'm working on a program which should edit a text file by adding/deleting some specific lines.By default this text file doesn't have these specific lines, so the program will add them.But I also want it to replace them if they're already in the text file.Basically this is my idea:- Read the text file- Search the specific lines- If they exist then replace them

I have a file in a certain place. I'm making a script with a button in it. For understanding. Let's say the text file has this written in it:
"ABC"
in it, How would I make it if I pushed one of the buttons, it would change that "ABC" to:
"CBA" ' Or anything else random "BCA", "CAB", etc.
and then save it?note I am using Microsoft Visual Studio 2010 so no VB v6.0?
