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.

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)."
[Code] .....

Read Certain Lines In A Text File?

May 1, 2009

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
Dim Open_File As New OpenFileDialog ' Dim Open_File as a Open File Dialog

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?

Jun 22, 2010

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.
