VS 2008 Compare Lines Within A .csv File

Nov 1, 2009

I am looking to compare lines within a .csv file. I want to start at the bottom line and compare values within it to those in the line above and then repeat the process, ie. the second bottom line to the third bottom line and so on.The code used to compare straight out variables I can handle, the difficultly for me lies in identifying particular lines and fields within a text file.If someone would be kind enough to provide the code for this, I have googled it but it's clearly beyond my ability.

Compare Offset Lines Richtextbox?

Mar 4, 2010

How can I get the sum from richtextbox, starting at line -1 ? But the first line should compare with line1.This code adds a constant to all lines and passes the sum to another textbox.

Dim num1 As Single
Dim sum As Single
Dim Constant As Single = Val(txtLowerTol.Text[code]....

So a third textbox should sum with one line "offset".

VS 2008 File Compare And Copy Or Rename?

Nov 3, 2009

I am helping a friend convert files from floppy to CD. The files are in WordPerfect for DOS (8.3)format. she named the files as follows: name.month eg; Baker.jan. if there were more than 1 "Baker" files in the same month she named them baker1.jan,Baker2.jan etc... She then copied them to floppies and when one got full she started another. The problem is I have multiple instances of the same filename on different disks so when I copy to my HD windows asks if I want to overwrite the files. I have been writing the names down and renaming them manually. Is there any way to automate this process? I would need to perform the following:

1. Check if floppy filename exists on HD already
2. if it doesn't, copy to HD
3. if it does, is it the same file or different file with the same name (file size has been a good indicator so far)
4.If it's the same =>ignore and go to next file on disk
5. if different, rename then copy to HD then go to next file
6. repeat until all files have been copied

I have 300+ disks to do this with and it is very time consuming.

VS 2008 Performance File Read/Compare?

Sep 15, 2009

this time im looking for a faster-than-fast way to read binary files into a string/buffer/whatever, like Delphi's BlockRead does.i need this for an application that checks a list of folders/files and looks for multiple files, and handles them according to specific criteria.

I know there are standard solutions for this, like DuplicateFileRemover (gotta love that sheep! ), but i need something custommade, coz i want to handle the duplicates automatically too, and im talking about GigaBytes of data i have to periodically clean out this way..So far, the algorithm i use to determine if 2 files are equal is this:

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.

2008 Count Lines In Textbox With Multiple Lines Using Label To Display The Numbers?

Sep 3, 2009

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.

example:

1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite

Obviously this is 5 lines and that's what I need to count.

I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.

[2008] Multiple Lines Of Txt File -> Single String?

Feb 26, 2009

I have a *.txt file which contains instructions and data, with its own comments (preceded by ! ), blank lines, and each instruction begining on a new line, but occassionally using two lines. Each instruction consists of several feilds seperated by a TAB. Finally each instruction ends in a comma. Only a few different instructions are there (10 different ones) but there are many of each. Spanning a good 2500 lines. Comments and blank lines are obviously of no interest to me. I merely need to read the instructions and the data that follows it.

Now, I have successfully used 'System.IO.StreamReader.ReadLine' to go through it line by line, picking out lines begining with certain strings (first 3 characters of a known instruction). All good, I can 'lift' out the lines of interest and store them, for them to be split up later (seperating their fields into instruction, data, etc..) and then into an array.

The problem is, since some of the data fields in these instructions are so long, it spans two lines, before it ends with a comma. Using the above method, I end up with two array entries for a single instruction, since I have stored individual lines rather than a complete instruction. The only similar situation I can tihnk of to explain this, is to pick out sentences in text, and store each one in a string. Of course these end with a period (full stop) but span two or more lines.

I am hesitant to post an example, since its formatting is rather strange, but it is generated that way from 3rd party software, so I cannot change that for my software application.Perhaps there is no 'graceful' way of doing this, meaning I would have to find a way of 'adding' the second line of the instruction, to the string of the first line. Or perhaps reading each line character by character, literally storing every number/letter until I reach a comma.

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.

Compare File From Server Then Update Local File

Jun 9, 2012

I'm making a game in Gamemaker and i'm using VS2010 to create a launcher for it. The launcher works like the Minecraft launcher:

it has to check a file from my server, then compare it to the local file, and if they aren't the same, the launcher has to re-download the game.exe from the server.

This all has to happen when i click play. To make the game start i use
Process.Start(My.Computer.FileSystem.CurrentDirectory & "\game.exe") i've put the game in the solution explorer.

put 'copy to output directory' to 'copy always'. i appareantly had to do that according to a tutorial to launch game.exe. Now, as i've said, i'm quitte new to VS 2010.
