Change Just One Line In A Text File?
Apr 11, 2012I have a text file with the format:
(title,price,id#)
CD1,11.00,111111
CD2,12.00,222222
CD3,13.00,333333
[Code]....
What is the best way to go change the price of the appropriate CD if I'm given the id# and new price?
I'm sure it has something do to with getting the line and splitting it, but I'm not sure how I edit just one line and not mess up the whole file.
Change The Value Of Text File Column?
Aug 14, 2009I have a line of tetx. I must change the value of X an Y column according to the initial value which is input by user. I have a text box for user to enter row and column and also text box for the user to enter intial value of X and Y
It should work like that. If have 10 lines then user wil input row =2 and column=5. Row always will be 2. Initial value for X=100 Y=100
the first line should be 100 100 whic is initial value.

X Y
100 100
102 100
104 100
[Code]....
How To Change Value Of Text File Column
Aug 13, 2009I have a text box for user to enter row and column and also text box for the user to enter initial value of X and Y. It should work like that. If have 10 lines then user will input row =2 and column=5. Row always will be 2. Initial value for X=100 Y=100. The first line should be 100 100 which is initial value.
My output will be like this
X Y
100 100
102 100
104 100
106 100
108 100
100 102
102 100
104 100
106 100
108 100
The X value must plust with 2 until X=column meanwhile Y remain unchange . then at 6th column which is second row X=100 Y will be intial value of Y+2=102 the the same process will be repeat for second row.
This is my code so far
Dim lines1() As String = IO.File.ReadAllLines("C:\wirematchesout.txt")
Dim xValue As Decimal = Val(TextBox1.Text)
Dim yValue As Decimal = Val(TextBox2.Text)
Dim altValue As Decimal = 2
Dim lineTracker As Integer = 0
[Code] .....
Now I don't want to depend on the column value which is input by the user. I want to do automatically.Let say If my text file contain 131 lines. Since my row will be 2 which is fixed so it should take 66 lines as first row and 65 lines as second row and do the process that I explain above. If line is 132 then it will be 66 for first row and 66 for second row.

FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text
Dec 19, 2008I'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.

View 8 RepliesReading Text File Line By Line, With Resetting Position To Beginning Of File
Jun 23, 2011I'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.

Comparing Text File Records Line By Line?
May 14, 2009I 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.

Search A Text File Line By Line - VB08
Apr 8, 2010I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
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")
[Code]...
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?
