I am having trouble removing a line from a text file. When I click on the button in order to remove the line it gives me an error that access to the file is not possible. Now I assume that the file is in use during me wanting to change it and therefore cant save it while it is loaded in ht application. I have tried a few things but cant seem to get it to work.Essentially what it does is that I have another dialog that a used can add data, the data is then written to the file FilingLocations.txt and then it saves it and loads it again. But once the line is no longer needed I would like to have the option to remove the line agaise.
Here is the code:
Private Sub cmdRemoveLocation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemoveLocation.Click
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]...
I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio
I have a textfile wich my app will have to read.The textfile will be like this
Hello=Bye SeeYou=SeeYa GoodMorning=GoodAfternoon
And so on, each line in the textfile will consist of two words seperated by a = Now I want to load this textfile and then be able to use each line and have a name for the word on either side of the = and then do something with line 1 word 1 and then do something with line 1 word 2 (word 1 beeing the first word before the = and two beeing the one after the =)
I have my code it is able to read a text file and do checks each line if there are 7W and 5L in that particular line, if no matches it will remove that line... 1 problem i face now is that, there are duplicates in my textfile..Im not sure how am i going to remove the duplicate in the text file. I want to know if there is a way to integrate an additional function inside my code to check if that particular line is a duplicate so i can accomplish 2 tasks at 1 time... Since there are about close to 1million records in my text file.
I have two text files and each text file has various columns (each column is separated by a tab " "), now some of the fields in column1 text file2 match the fields in column1 text file1. What I'm trying to achieve is to remove every row in text file 1 where the field in column1 matches the field in column 1 textfile 2 - is this possible?I have used some basic coding in the past to remove certain lines, but nothing as complex as this.
Dim linesList As New List(Of String)(File.ReadAllLines("Path")) linesList.RemoveAt(1) File.WriteAllLines("Path", linesList.ToArray())
I use the following coding to replace a word in my textfile, would it be possible to add any coding that will remove all blank lines from the same text file? Dim EditMyFile As String = IO.Path.Combine("D:Test.txt") Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2") IO.File.WriteAllText(EditMyFile, inputFile)
I have tried the following but it doesnt work. Dim EditMyFile As String = IO.Path.Combine("D:Test.txt") Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2") IO.File.WriteAllText(EditMyFile, inputFile) Dim sText As String = File.ReadAllText("D:Test.txt") Dim sNewLines() As String = sText.Split(New Char() {ControlChars.Lf}, StringSplitOptions.RemoveEmptyEntries) File.WriteAllLines("D:Test.txt", sNewLines)
I'm making a function that is supposed to delete a line from a textfile "test.txt". I'm having no problems with finding what line i want to delete. The basic idea is this: read the whole file with streamreaderdelete the linerewrite the file with streamwriter. My problem is the last, how can i completely remove the file content, and write another string in it, writer.writeline just appends a line.
I have a program that reads a text file tab delimted using OLEDb I need to be able to allow the user to insert a user created record into the file which I can do. The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record?
Dim strDelimiter As String = vbTab OpenFileDialog1.InitialDirectory = "C:\" OpenFileDialog1.Filter = "Text Files (*.txt)|*.txt"
I have a program that searches for a word in a .txt file. When it finds the word I want to print the following 5 lines under that word. So for example: I search for "juice", and my label grabs this out of the textfile: juice apple grape orange milk Is there anyway to this in VB.NET?
how do i have my app read a line from a textfile and if that line equals "whatever" proceed with command, this case a msgbox.so much work to do and so many choices to choose from...
I have not had much time to go threw my code properly as this is some urgency. I need to remove line 1 from a textfile if it contains a string but its not working.I have 500 files and not going to do this manually.
Code: Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click If String.IsNullOrEmpty(txtDirectory.Text) Then OpenFolderDialogDirectory()
[code]....
I also feel the function is very pointless sime i am opening the file twice.
i know i have to use a loop to get each line of the textbox onto a newline of a textfile but i dont know how to figure out how many lines of text the user has entered into a textbox. I tryed using a try statment to loop until it errors, it seems to work sometimes but other times it only takes half of the textbox and adds it to the textfile. And if atmaweapon reads this, i tryed to make better names for variables. Here is my code,
Code: Path = ("Meals" & ComboBox1.SelectedItem & "" & TextBox1.Text & ".txt") File = New System.IO.StreamWriter(Path) If ComboBox2.SelectedItem = "1" Then
[Code]....
how many line of text there are... im not so shure how good it is to run a loop tell it errors for a textfile, but its the only way i could think of.

I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???
Dim pathdir As String = "C:workingdir est.txt" If System.IO.File.Exists(pathdir) = True Then Dim objWriter As New StreamWriter(pathdir)
