VS 2005 Write To A File?
Jan 4, 2010I want to read through a flat file, find the line starting with the number I want, and edit that line.So if the file looked like
01435804385043295
02843759248752092
03854379857394857
and I want to edit the value 4375 in line 02 (pos. 4-7) to be 4376.I know I can read it with a streamreader, and write to the end or entire file with streamwriter, but how can i read and write at the same time?
Downloading the entire file to a string and then recreating is NOT an option.

.net - Create And Write To A Text File?
Mar 16, 2010I'm creating a small vb.net application, and I'm trying trying to write a list of results from a listview to a text file.

VS 2005 - How To Write Line Into Text File (CFG)
May 17, 2011I want to write a line into a text/.cfg file. The line is = name "ishtiak". I need a sapce between name & "ishtiak". The text "ishtiak" is loading from a textbox called textbox1. I dont want in the text box my name like this "ishtiak" it will be without "" like this ishtiak
but in the text file it will add "" before & after my name.
So the question is

2. My textbox text will be ishtiak,but it will be written like this "ishtiak"

Dim thefile As String = "C:append.cfg"
Dim lines() As String = System.IO.File.ReadAllLines("C:append.cfg")
lines(4) = "name" & TextBox1.Text
System.IO.File.WriteAllLines("C:append.cfg", lines)
End Sub
VS 2005 Using VB Through SQL To Read/write To/from File System?
May 21, 2009I have an application that currently stores PDF files (and others) inside the database as BLOBs. The trouble with this method is that I've now got SQL Server databases in excess of 200 GB! I've finally figured out a way to still enable full-text search without needing to store the PDF files as BLOBs (yay! Adobe's iFilter isn't great.), but I'm having trouble designing the method for a client to get access to the files stored on the server's file system.
I want to place the files in a restricted directory on the server, so I can't simply pass a UNC path to the client and let them open the file from there either in a browser or using Process.Start(filename). I understand how that would work, but if that directory has user access granted, all sorts of security holes open up, right?So, what I'm thinking about is a way to have a SQL Server account that has read/write access to/from the protected file system directory. That way (in my mind), the SQL Server can take a file as it's loaded in through the import client (as a series of byte chunks) and write the file to that area of the filesystem. Then, when a file is requested, the SQL Server can bulk load the file into a varbinary(max) field and do whatever I want with it.
1. How can SQL Server take a stream of bytes and write them to a specified location on its local file system? (This is assuming that I want the import utility to be able to be run on a client machine and not require it to be run on the server itself.)
2. Is there any way to stream a varbinary(max) file to a web page out of SQL? I'm using a lot of PDF files that will have Fast Web View enabled, so if I can stream the bytes to a web page, the user will be able to see the first few pages of the document while the rest is loading. I thought about having the SQL Server read (bulk load) the file from the protected area and write it to an unprotected area just long enough to point a web browser to that location, then wiping the file, but that brings me back to #1 above and would THEN require me to be able to issue a delete command from SQL.

Feb 19, 2011Im trying to write to a file I created and place "Unregistered" in it. Thought it would be a simple task but keep getting an error. Its happening when I try and open the file to write. This is the error: Access to the path 'G:\Projects\Project\pbss\bin\Debug\5\pbssv\Data.DB' is denied.
Ive tried adding the file attributes to read-write and still get the same. Most of the code ive looked at via a google search points to the same as ive got for the Added default value area. Im not sure if there is a conflict between the 2 different ways im accessing the file when creating and writing too? [Code]
Create Txt File And Write To It Without Access Denied Lock?
Jan 24, 20121. I have to create a file. 2. Then I want to write a string into the text file.
I can do part 1 no problem with: File.Create(strFilePath) But when I try part 2 to write to the file it won't allow this as it's still being used:
sw = File.AppendText(strFileName)
sw.WriteLine(strCode)
sw.Flush()
sw.Close()
My code in part 2 works fine on a file that hasn't just been created.
How do I release the file from the File object?
There doesn't seem to be a .close or .flush option.
VS 2005 Refuses To Write To A Text File If The String Used To Be A Path
Dec 13, 2009I've searched everywhere to find out why the heck my program is doing this, but couldn't find anything like it...? I'm making a flash card program. Part of my program takes images corresponding to other data from a certain area, chosen by the user, and moves them to another folder, for later use. I want to store the path for the image next to the other data, storing the path as a string. When no image is chosen, the variable for the path is simply "no image".

Sep 2, 2009I have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

View 9 RepliesVS 2005 : Create A Source To Get The Strings From The Text File Using ReadLine Method?
Aug 22, 2010I 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.
