File I/O And Registry :: Each Line Of Textbox To A Newline Of Textfile?
Aug 24, 2009
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'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 some coding which displays a label if the value of a textbox matches the first value of each line in a textfile.
Dim sList As New List(Of String)(IO.File.ReadAllLines("Path"))
Dim i As Integer
For i = 0 To sList.Count - 1
[Code]...
The problem is if the textbox has 1 and the textfile has 11 it will display the label, what would be the best way around this?
I have tried sList(i).Contains etc but none of them are doing the job.

I have a txt file, that i want to read into my program. The problem is this:The textfile is a stats file for a game and looks like this:
Code:
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
etc.
The main thing i want to do is sort these things out and then add to mysql database table that would have these columns:
Code:
ip authid wins username points
So what i wanna do is splitting this textfile data up and then adding everything to a mysql table.

I have written an import routine, that imports a textfile into a database table, using a schema.ini.In the input file, 3 fields are seperated, that should be concatenated in the import-routine. Does anyone know how I can make that happen...Small part of the import-routine, first lines are the last lines of the programatically created schema.ini.
Code:
PrintLine(intFile, "Col11=mededelingen1 Text")
PrintLine(intFile, "Col12=mededelingen2 Text")

I'm trying to read an .rtf file one line at a time but I'm clearly missing something!The file contains 3 lines and I want each line to end-up in a different RichTextBox, so:
Open File
RichTextBox1 = 1st Line in File
RichTextBox2 = 2nd Line in File
RichTextBox3 = 3rd Line in File
Close File
What am I not understanding? I've tried using LoadFile to load the whole file into another RichTextBox first as I got the impression that RichTextBoxes are indexed - but what I got was strings not .rtf format. I've also looked to see if there's an equivalent of the text-centric ".ReadLine" and nothing seems to fit the bill.

I cant split a line by a newline in silverlight vb.net I am reading in numbers from a file into a string as this is the quickest way. Then I parse the data in numbers by splitting the string by newline then by comma. I cant split by newline which again is the sticking point as nothing happens with the newline split.

I thought you could use a structure as a container. I have line_1 with a line of data read in from a file. I only want to Look in position 1 of the line and position 8 for 9 and position 31 for 11. If I create a line_2 with the parts broken out for pieces that I want to look at then I could use a with statement right?

I am in the process (slow process) if learning vb.net by trying to create a simple application that will read and write (save) chosen information to a text file. The application has text boxes (name, email address, etc) and I want to read information from certain lines in the text and place in the given text box.
Code:
Dim StreamToDisplay As StreamReader
StreamToDisplay = New StreamReader("C: esting estfile.txt")
TextBox1.Text = StreamToDisplay.ReadLine()
StreamToDisplay.Close()
Currently it's reading the first line of text (which is "[username]").
Text file (testfile.txt) is attached

I am trying to add a line of text to a TextBox component in VB.net, but I cannot figure out for the life of me how to force a new line. Right now it just adds onto what I have already, and that is not good.I have tried copying the actual linebreaks, didn't work. I tried AppendText(), didn't work.

I am using a Rich TextBox in VB.NET and passing to a StringBuilder. I need to replace the New Line character from the TextBox with either a space or a comma. Problem is the standard codes for new line don't seem to be picking up this New Line character in this case. Is there a specific character used in Rich TextBoxes as the New Line?

I'm trying to count characters in a textbox, which includes newline characters and tabs. How do we know if the textbox contains only newline characters? ie or if the user types in one or more characters, then a bunch of "newline" characters (CR followed by LF) and then goes back and deletes the original one or more characters leaving only the leading "newline" characters. I don't want to count the characters in textbox only if new line exists..
If String.IsNullOrEmpty(TextBox1.Text) Then
Label5.Text = 0
Else

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 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

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?
