Reading Text File In Directory And Finding Certain Strings
Mar 11, 2010
All I am doing is reading each txt file I find in a directory and finding certain strings in the text then counting how many I find in each file and then once each file has its separate counts it send it to a sql database. I have most of it done, but I cant seem to get the count to separate each file so my problem now is that it counts the first file but when it counts the next file it adds to the first file and so on through all the files
I have 4 directories, each directory contain 1000 text files. what i want to do is read all text files in the 4 directories then save them to 4 array of sting. i.e each directory of text files in on array of string.
I am fairly new to vb.net but was programming a long ime with vb6 I have a binary file that is a mixture of numbers (integers and doubles) and strings, such as "Programming with VB". I read the numbers using the BinaryStreamReader.ReadInt32 and BinaryStreamReader.ReadDouble, which are no problem
Is there an easy way to find a certain string within a string and then return the strings that you find as an array?I have written this:
Public Function FindStrings(ByVal strSourceString As String, ByVal strStartString As String, ByVal strEndString As String) As String() Dim StringStartposition As Integer Dim StringEndPosition As Integer Dim Currentposition As Integer = 1
I wrote a cleanup program to go through some directories and delete files based on if the creation date is older than say 6 months. It works fine with some of the directories I have that contain around a few thousand small files. However, there is one directory (that contains small backup files from another program) that is loaded with over 300,000 files and it locks up on me as soon as I read in the first file in that directory.I am convinced it is the directory has too many files in it to open it. The server that the directory is on is slow. It takes a half hour to open the directory while on the server itself. I know it will take forever to delete the amount of files I want to delete, but I don't understand why it gets stuck and hangs there with no error message.Here is where I get stuck. Listbox1 is the directory I'm attempting to access
For Each selectFile In My.Computer.FileSystem.GetFiles(ListBox1.Items.Item(Count), FileIO.SearchOption.SearchTopLevelOnly, "*.*") compFile = Path.GetFileName(selectFile)
I'm storing a multi-line text file (in .dir format) in the directory the user chooses, and what I need to do, is when they import it (which my program can already do) I need it to find the end of the file (line) and then read that line, that line will be a number which corresponds with a number system. Basically, the file looks like this
1. Time: 10/27/2009 4:58:09 PM Title: Title Author: Author Entry: Test
2The 2 at the end specifies what the number will be next time. How do I do this?
I've been writing a socket application in which the client sends a user/pass combination which the server compares to a local text file. I'm only hacvin a problem with a small section where I have a do loop which does this comparison:(the string 'fromclient' has been defined earlier, as the information was received from the client)
fromfile As String Dim sr As StreamReader = File.OpenText("C:PASS.txt") Do While sr.Peek <> -1
In a text file I have users add a folder using the folderbrowserdialog users then push add which appends the text with lets say they selected downloads
Downloadsname=Downloads downloadspath=C:documents and settingsJamesDesktop
how can I make it so that when they push a button it seraches for downloadsname then after the = is the text to use as a string and do the same with downloadspath
I am working on arrays and I am currently having trouble with searching and finding arrays. In this example, the user should be able to enter a Name, and it will output that person's stats.
Here is the text file (note, I should be able to go to this text file, add a few more names and the code should still work, which is why I am using loops,arrays,text files instead of if and else statements),
Kobe,29,6,4 Allen Iverson,28,7,4 Jason Kidd,12,10,9
So if the user enters Jason Kidd in the text box, this will display in another text box:
Jason Kidd averaged 12 points, 10 assist, and 9 rebounds.
[Code]...
All right now is the searching part. I really do know how to search for what the user entered and display the statement in a text box. I kind of have an idea of how to just get the name, but for it to get the name and then all the data for that name puzzles me even more.-I tried using .contain, indexof and few others.
I know to display the information in the text box will be something like:
I am working on a project in VB 2008 and need it to do this:Read first line from text file (using Openfile)Enter line into textbox on formDo some other codeThen Read second linefrom text fileEnter line into same text boxand loop until we have gone through text fileI am not sure how to read line by line from text file then enter it in textbox. I can open the Openfile and get the filename and everything, but I just am not sure how to read from it or enter that line into the textbox.Here is what I have, its not much but its a start:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim FileReader As StreamReader
Well I basically know how to read a text file, replace text then write to one. how to append text after a specified string (ie, insert text at a specified line, removing the text after a string in a line and changing it without altering other lines, etc). Can someone please tell me how I would go about adding a string after a certain string in a text file? For example:
What I need to do is find a string that can be any value, and is placed between ">" and "</" with a minimun length of 5 and a maximum length of 7 and contains exactly 2 dots.
So if I have a text file like this:
<a href="www.site.com">a site</a> text<br /> More test<br />
[Code]....
I want it to find only the 5.0.77. And no, the number isn't always between h2 tags, and the number isn't even always the same. The only thing that is static about it is that is is between ">" and "</" and that it is between 5 and 7 characters and contains 2 dots.
I want to read the whole file, and split the colums so each set of numbers is put into an array to be used as an input for later. If the text file only contains one line of numbers like 00100 25690 21586, I have written a code to seperate those and put them into an array which is attached. If the text file contains more than one row of numbers I can read the whole file in line by line but I can't get the strings seperated.
Alright, my program requires a folder to put the save files in, and it works fine to create it when I know where the program was installed to. I want to assume that everyone will install to C:/Program Files... however, one cannot assume. Is there a way for me to find out where the program was installed to ie. D:/WorkPrograms/ProgramHere, instead of the Program files? Specifically, is there some sort of code that I can run at startup to find where the program file is, so I can keep all the save files in there?
I am trying to write login page code for the login button but can't find how to find a string in a .txt file. The only code I have managed to find on the subject is opening up the text file with the
FileOpen(1, "File location", OpenMode.Output) code, but even this would be best removed as it would open the text file containing all usernames and passwords within the file.I need the system to search for a specific string within a file ( Usernames___Passwords.txt (159bytes)Number of downloads: 134), and with that string find the password associated with it (in my attached example the letters/words after the apostrophe) but stopping at the end of the line.
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then EnglishForm.Show() ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String TempFile = "temp.txt" Dim sw As StreamWriter
I'll start off by saying I am using Visual Studio 2008 Standard. I am creating a program that will open installed programs using short code. For instance, if a user types in 'npp' then Notepad++ opens. I have it working just fine to respond to the predefined commands, but I would like to expand it so that the user can define their own settings simply by typing the program directory and the custom short code they want: Example: If I am an end user and would like to say define a short code for Windows Media Player, I would simply type the following: (Assuming Excel or likewise is used to open the csv file).
I am trying to parse a very large text file for certain strings. The text file is part of a level-making software for an old game I play. The text file basically contains all the information the level designer software needs, but the only important bit is the 'texture information'. Basically what I'm trying to create is a little program that parses the text files and shows the user a list of every texture in that text file. The problem is, the strings denoting textures are not really easy to find, and I can't think of any sensible and fast way to get them...
I've got my self in to a pickle here.I'm trying to do something I used to do in basic? At-least I think you can do this in Basic, you know Qbasic,What I'm trying to do is put 4-8 strings on to one line separated by a comma.Example might be:
writer.writeline (bob1, bob2, bob3, bob4) Out put might look like Test, Test2, Test3, Test4
I'm tried looking in to formatting of writeline/write, but I didn't get any where with it.
Also if this is possible- I would like to be able to read it just like :
reader.readline (Rbob1, Rbob2, Rbob3, Rbob4) If anyone cold just point me in the right direction, I'm sure I can figure it out - If not... Well I will ask another question.
I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]
How do I play a WAV file while the computer is reading aloud a text file? It uses Text to Speech synthesis and I need a laughter wav to play when the computer comes across something funny in the line.
I need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1 random item 2 random item 3 random item 4 random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1 example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2 example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3 example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4 example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.
