How To Read The Last Few Lines Of A File In VB

Oct 21, 2011

We have a file to be read each time a code is run. Every 15minutes this file keeps growing by adding lines to its end.(Somebody does this beyond my control)

(My job:) Each hour I run the code, I need to read the new lines that are added to this file and store it into a database.

Usage:I am using the StringReader class in VB in which I am force to read the entire file atleast once(ReadLine) to reach the end.

Question:Is there a way in which I can Navigate to the end of the file and just read the last few lines each time?

Read Lines From Text File 1 And Delete Those Lines From Text File 2?

Sep 15, 2009

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.

Jump Through A File And Read Lines?

Jul 28, 2009

I want to use a FileStream and seek from the beginning of the file while moving forward in the file .01% of the file size at a time.

So I want to seek to a position in the file, read the entire line, if it matches my criteria I am done. If not, I seek ahead another .01.

C# is OK but VB.NET preferred.

I used to do it something like this in VB6...

FileOpen(1, CurrentFullPath, OpenMode.Input, OpenAccess.Read, OpenShare.Shared)
Dim FileLength As Long = LOF(1)
For x As Single = 0.99 To 0 Step -0.01

Read Certain Lines From Text File

Mar 24, 2011

I have this code now doing and that is creating my chart from data off a text file. The final task I need to be able to do, to complete my program is have a way to select how many days of data to populate my chats with via a Text Box input. I am thinking I will need to read the complete text file first to count how many lines are in it, then what ever is put in the text box it will take that many lines of data from the text file and populate the chart. For this to work correctly it would have to read the lines of the file back wards.(last line of file would be the first line..) e.g. textbox1.text = "7" then the chart would show only the last 7 lines of my data.

I was looking up examples of Counting the lines in the file, I think I am close here...
Dim fso As New FileSystemObject
Dim txt As TextStream
Set txt = fso.OpenTextFile(ReadChart, ForReading)
txt.ReadAll
Textbox2.text & txt.Line & " line(s)."

Read Certain Lines In A Text File?

I want to make a program that reads the line of a file, and puts it into a text box, then reads the second line in that file, putting it in another text box... Say i only have a file with two lines, how can i do this?I have written a code, but it only works for the first line. Is there a preset function in Visual Basic that will allow me to read a certain line?

Imports System.IO.StreamReader
Dim AllText As String = vbNull, Lineoftext As String = vbNull

Read Single Lines From .txt File

Mar 4, 2012

I am using vb 2010 and a windows form in my Web Browser project. In my favorites bar I need to be able to import my users favorites (that he may add) through a .txt file. I realize one way of doing this is creating multiple files stored in one master folder and reading the whole file of each which would contain the URL, but I would much rather have them all in one .txt file, but for that to happen i must read line by line from that file to import the favorites. Therefore, my question is how can I code my project to read through a .txt file line by line and return each line in possibly an array? "We are what we repeatedly do. Excellence, therefore, is not an act but a habit."

VS 2010 - How To Read Lines From File

May 4, 2011

I need to read lines from file. Now my code is like this:
Sub data()
Dim reader As New IO.StreamReader("log.txt")
For i = 0 To 1500
date(i) = reader.ReadLine
Next i
End Sub

Now if some user will change add or remove the data from this file, it will end up with error or sth. I also tried to write sth like this:
Open "C:in.txt" For Input As intInFile

But there appears an error, that open is not declared and IO functionality is microsoft.visualbasic namespace. I added this name space (at the top: Imports Microsoft.VisualBasic), but this error still occurs.

Read Individual Lines Of A CSV File Into A String Array, To Then Be Selectively Displayed Via Combobox? Input?

Apr 2, 2010

I've got myself a CSV file with the following contents:

1,The Compact,1.8GHz,1024MB,160GB,440

2,The Medium,2.4GHz,1024MB,180GB,500

3,The Workhorse,2.4GHz,2048MB,220GB,650

It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on. (I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.

It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:

Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()[code]......

But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:

"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."

If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array."

Dim name As String[code]............
