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! It will loop 100,000 * 100,000 times!How can I find another way to compare these files quickly; or another idea for my full-text index with text files?
I have a vb.net program in which i must compare three text files(two against one) and verify that they are all same. Even if there is one change i must know where the change is, which text file and which line. The format of the text file is like this
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 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 want a code for compare between 2 text files A.txt and B.txt all record in file B.txt includes in file A.txt but with different value.the digits with color red are accounts and the digits with color blue are values.i want to compare between A.txt and B.txt based on accounts,when find the accounts from B.txt in A.txt copy the full record for these accounts from A.txt and print it in new file C.txt
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.
I have a multiple text files that I need to merge. but I need to compare the reference number before merge it.[code]What will be the fastest way to deal it read line by line to compare. the text file consist of thousand of line
I have a monster of a problem and don't know where to start. I need to create a simple application that will: have two open file dialog boxeseach file box, one can choose the .txt file to compareonce each box has a file location, click a button that starts. My boss man wants the results saved as :
I started with not knowing anything and I have built 2 programs over the last month and a half and have learned valuable information from the help of this board. I have 1 last hurdle before I am done and I am hoping to get another tip for this. First of all let me start by explaining what I have done.
I am working on a application that stores videos, images and files. I would like to give the user the possibility to encrypt them. I am tying to use AES to encrypt them but the problem is that the decryption takes to long.I was hoping that the loading time from the hard disk of the encrypted file was far longer than the process of decryption of an image for example but i was wrong
So if i try to 1) load the image 2)decrypt it and 3)load it in a image control it takes 15 times more time that loading the original file not encrypted
I have 202 .html files and at the beginning of each file, I need to add a chunk of php code. I could make this myself, but to be honest, it would take me forever and I might as well just manually edit them lol. All the .html files are in one folder.[code] one other thing that would be VERY cool, is if it could add the files that are not edited to a listbox or an outputted text file.
I am attempting to create a basic program and I need to know how to incorporate INI files for profiles in order to quickly pull up data from one person to the next.
Public Class IniFile ' API functions Private Declare Ansi Function GetPrivateProfileString _ Lib "kernel32.dll" Alias "GetPrivateProfileStringA" _
[code]....
And placed it into a module, which I then wen't to my main program and attempted to place this:
Dim ini As New IniFile(Profiles.ini) Dim value As String = ini.GetString("Names", "1", "Default Value")
To attempt to retrieve the data, but I get no error or information from it. The ini file is inside the folder of the project and I set the SectionName and KeyValue to the corresponding names. I think I am having trouble with syntax? Not 100% sure. This is the code that I got from the same source as the module for using the module.
Dim ini As New IniFile(FileName) Dim value As String = ini.GetString("SectionName", "KeyName", "Default Value")
And I adjusted to what I believed would be the proper format.
In developing a flash-based memory manager, I need to be able to view large quantities of data. With my eyes and monitor resolution, I can read hand-drawn 3x5 letters on a 4x6 matrix without too much difficulty, but none of the system TrueType fonts render optimally at that size. I've tried writing code to draw font shapes to off-screen bitmaps, and then use DrawImage to copy those bitmaps to the screen, but I can't get good performance. This is for development, not production, so performance doesn't have to be absolutely optimal, but I don't want to spend too long waiting for screens of data to refresh.
What would be the best way of either making .net display a font which is pixel-perfect what I want, or else building a bitmap out of lots of little pieces quickly? I'm using vb.net, so I can't simply generate a bitmap as a byte array and pass that to the Bitmap constructor unless someone can show me how to convert an array into an IntPtr.
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 a form which contains a large number of textboxes covering numerous panels/tab controls and I would like to have the user only have one text box visible at a given time and when the user clicks on the screen to another label with a corresponding text box I would like that to appear and the other currently open to disappear. Currently I have the following loop that goes through and changes the visibility of the appropriate controls unless it is the name of the control I am looking for:
'This is used to iterate through all the controls in the form and ensure the visibility of all other controls ' than the active control is set to false.
I just put 2 datagridview in form1 and both datagridview got filename and MD5 hash. but some data in datagridview1 and datagridview2 got different MD5 hash but same filename.. but how can i compare both MD5 hash and put it into another datagridview (datagridview3)
, I can get the same result (depend on the third column to compare), then i must save this result to new txt file . Examples, this result from 2 txt files:
I need to check files in one directory that end in 'ilk' and compare it to another directory with files that end in 'txt'. If the file name matches (with the exception of the extension), then I want to delete the file that ends with 'ilk'.
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.
I want to compare some files from a textbox to ones in a directory. E.G.: =================| TEXT BOX SAYS | =================| textures/tools/_caulk_concrete0 textures/finca/dirt textures/finca/concrete_block textures/finca/stucco2 textures/finca/stair_woodfront [Code] .....
Ok, stay with me on this one.I have a bunch of css files with classes defined in them.They are like this:.toolbar{......}.addpage{......}
I have managed to extract the just the classnames with a bit of help from a fellow member.now i have another bunch of .vb, .aspx files which use these css classes in them. they in the form:<id=23441:cssClass="toolbar">Now I have to extract the classnames after the 'cssClass' key word and then compare all the classnames with the previously extracted ones and determine which Classes are not being used.
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.
Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
Catch MsgBox("Selected Hero currently has no File with us.") End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
