App To Compare Data In Various Text Files?
Dec 7, 2010
I have been tasked with creating an app that will read in various text files(.csv, .txt) and compare some of the data contained within.
I thought I would read in the files and convert them to datatables. Once I had them in a datatable I figured I could remove the unnecessary rows/columns and then sort and compare the pertinent info for differences. The difficulty is that the various files are formatted differently so I will need to get each type formatted correctly. Is this the best approach?
I have read in a .csv, parsed it into a datatable, but I'm having trouble with the logic/coding to get rid of the rows and columns that I don't need. Also, I'm not sure how to handle a row that has a cell with a comma seperated list of values that will need to be split into individual rows.

I've been tasked with writing an app that reads in various text files(.csv, .txt) in different formats with different delimiters.I then need to compare certain data in these files and report the differences.There are a couple of columns that are common between the files, but they aren't in the same place, and there is inconsistent and unnecessary header info.There is extra data(columns) in these files that I don't need.Should I parse these files into a datatable? Should I create an object for each file type to format the data and get rid of the unnecessary info?I'm not sure about the best way to tackle this problem.

I want to create my special full-text index using text files, without database.I saved records ids for every word in index, in text file..Now if I want to search for tow words together; I have to get ids that is shared between these words by comparing text files of these words ids; and saving the result in other text file.[code]But now the problem if the first word has 100,000 ids and also the second word same it; the loop will take too long time!

Well, I have a MenuStrip1 with submenu "Open File1" and "Open File2".
An OpenFileDialog1, two RichTextboxes and a button called "Check".
When I open txt files into RichTextboxes, by clicking the check button i want it to compare the two contents and focus the differents with a color (let's say yellow).
I have created a simple project and at the end it only says with a MessageBox if files are the same or different.
Here is my

I need to compare the data between two text boxes and a variable. If the value of the boxes don't match up and the variable is -1, I need to fail it.When I do this:
VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text Then
I have no troubles, but adding the variable check produces a false positive.
VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text And TestData.BypassCheck_PCID = -1 Then
The way the code is laid out, I have to do this in one line. I can't check the first condition on one line and the second on another.I've tried separating the data out with parantheses, but it's producing the same results.

I've been trying to compare two text files line by line but I was only able to compare the file lengths. I'm creating a dance mat game and I have a text file of the steps that should be taken to get a perfect score and a text file of the actual steps taken by the user. Each text file contains a time stamp and a binary value indicating which arrow was stepped on. I'm using streamreader and streamwriter to write and read the text files.
Code:
Private Sub Score_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have created an vb.net windows application. In the application i have 2 xml files (e.g., Pre.xml & Post.xml) & the 2 files are same structure.
My requirement is compare the pre & post xml files and get the differences between xml files. Like what are all the newly added nodes, removed nodes and modified nodes as well.
I tried with XmlDiffPatch.Dll, it is working for small size xml files, but in my case xml file size should be upto 100+ mb.

so here is my scenario. I have two input files... both are plain text files. File1 has customer name, customer address and invoice number. File2 has customer name, customer address, invoice number AND a keyline. File1 will only contain some of the records in File2, and it will change daily. I need to be able to compare File1 against File2 and output one file (preferably an Excel spreadsheet) with the info from File1 and the keyline from File2, that matches the duplicated info. I know the basics to get it to work, but I'm not sure what would be the easiest way of doing this... File2 can have up to 100,000 records per day. I'd only need to run it once a day though.
