I am trying to make a button so when clicked will remove all text from a string except for one line. I have tried several methods but it didnt seem to work.
I have text file that need to read until *+*+* Top *+*+*and write the content until *+*+* Top *+*+* but i dont want to write *+*+* Top *+*+* this line[code]...
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.
Basically I've got a list of items in a text file, but sometimes a blank line gets inadvertently put in there, and I need to be able to delete that line (or change that line to a set value, either is fine).
my program can add new lines and select url's but I can't get the remove button working, I read that (maybe) I have to read all lines and write a new file.
If removename = currentfield Then Dim removedata As New System.IO.StreamWriter("z:station.list.txt") removedata.Write(""(currentfield)) removedata.Close() End If
I remove a line from a textfile with the following code. It works fine, but when I remove the first line, a blank line has been left. How can I fix this?
Public Sub DelLineFromFile(ByVal filename As String, ByVal line As Integer) Try Dim lines As String() = My.Computer.FileSystem.ReadAllText( _
I currently have a bunch of text files I need to edit in a folder, I need to edit each file and remove the same line but not all files have this line, so I need to create a script that needs to check if the line exists then remove it.I have 1000s of files, that's why I need help to be able to create a script that does it for me instead of me editing each one manually.I am not sure on how to do this, but I am sure it is not difficult for people that have good experience with VB.net.
How would one remove an item from a ListBox and then remove that line from the TextFile and repopulate the ListBox with new data in Visual Basic.Net?[cod]...
Basically 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.

I'm using text files as an array to store and remove information, however I do not know know how to adapt this code so the line I search for is removed.
My text files are set up as such: 021,Donovan,56 Eynesford Crescent,Bexleyheath,CT5 1TR,09/08/1967,13 March 2012,Bronze 062,Fredrikson,6 Freil Road,Gravesend,CT9 1RB,12/06/1995,13 March 2012,Silver
So I can search and locate the ID, in these cases 021 or 062, but I want to be able to remove the line I want, once it's been found.
After I add tons of text lines on RichTextBox, I need to select any line(s) by just clicking this line. After that this line is highlighted. Then I click one button to remove this line. How to do that? (the starting character for each line is the same)
1) Whenever i change the text in my richtextbox it flickers, as part of my program a richtextbox is changed every 1-2seconds and the flickering can get extreemly annoying, anyone know a way to stop this?
2) Im looking for a function that when passed a line will run through a textfile and remove said name for example in a textfile that contains
I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....
I have a list of random numbers in my text file.I read it like this.

Dim sFileName As String Dim srFileReader As System.IO.StreamReader Dim sInputLine As String sFileName = "D:UsersArbenDesktopSerieA.txt" srFileReader = System.IO.File.OpenText(sFileName)

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
I'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.

I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.
