FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text
Dec 19, 2008I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
VS 2008 Reading Text File Line By Line - Put Into Text Boxes
Sep 21, 2009Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
View 8 RepliesReading Text File Line By Line, With Resetting Position To Beginning Of File
Jun 23, 2011I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

Comparing Text File Records Line By Line?
May 14, 2009I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

Search A Text File Line By Line - VB08
Apr 8, 2010I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")
[Code]...
as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?

Reading A Specific Line From A Text File And Displaying It In Individual Text Boxes?
Feb 16, 2010I'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.

View 6 RepliesFile I/O And Registry :: Creating A Text File, And Using It Among Different Windows Users
May 31, 2009I created an application that when a user logs onto their Windows account, a Form is displayed outlining the current Computer Usage policy set by the insitution and gives the user two options either Agree or Dis-Agree. The two options are in the form of buttons, with events that depending on what the user clicked, will create a log text file at a specified location, with enteries of Date,Time,CurrentUser, and if they agreed or disagreed. If they agreed the application after creating/amending the file will then terminate, otherwise it will update the file and then force Windows to logoff the current user.
Now I made a shortcut of the .exe of the application and placed it in the startup for all users, and yes the application loads at startup for all the users following the procedures mentioned above. The problem I am facing is, that if the current user logs off, or is forced to log off, and another user logs onto Windows, goes through the whole ordeal mentioned above, the application is denied access to the logfile that was created under the previous user, and thus crashes.
So my question is, how can I created a text file using vb 2008 application, that is accessible by multiple Windows users. I have even tried changing the location of the created file to the shared folder, but the end result is the same.

Text - Ensure That A File Has Unique Line If The Size Of The File Is Very Big
Apr 4, 2012Language: vb.net
File size: 1GB, and stuff.
Encoding of the text file: UTF8 (so each character is represented by different numbers of bytes).
Collation: UnicodeCI (when several characters are essentially the same, the most popular version will be the one unique.). I think I know how to handle t his one.
Because each character is represented by different numbers of bytes and each line has different numbers of characters, the number of bytes in each line also vary.
I suppose we have to compute hash for each line. We also need to store buffers location where the line each. Then we have to compare buffers. Then we will check whether the same line shows up or not.
