Move To The Next Line In The Txt File?
Jan 25, 2011
I have a text that has a question followed by four possible answers. At the start, it loads up line 1 of the text file and puts the sentence fragments into their proper place (text.split is being used). I want to be able to have a click button event that then reads the second line and replaces the first line's sentence with its own. Click the button again, it goes to the third line.
This is what I've created. It reads the first line (But honestly, I think it reads the entire thing and the first line is the only thing that can fit in the selected spots). It then splits the first line into fragments, moving them to certain areas of the form. Question goes to the Question label, answers go to the selected button.
HTML
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim readText As String = ("C: est.txt")
Dim textParser As New TextBox
[Code]....
So, like I said, what would make it possible for me to create a button event that when I click on it, it moves to the next line in the txt file?

After my program enters a string in my multiline text box, how do I move to the next line??
I've looked around the forums but cannot find the answer??
The current Method I use is the textbox1.append, but I need to move to the next line rather than keep adding to the current line?

what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.
full code here
-------------
Dim objReader As New System.IO.StreamReader(sOpenFile.Text)
Dim sTextLine As New ArrayList()
Dim sText As String = ""
Dim i As Integer = 0

Currently there are functions to draw line or move to points, commonly known as LineTo(x,y) of MoveTo(x,y). I am wondering if there is also a LineTO or MoveTo function(s) for 3D, i.e. LineTo(x,y,z) or MoveTo(x,y,z).

I'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.

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 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.

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 code that reads the whole file, not line by line.
Here is the code:
FileOpen(1, filename, OpenMode.Input)
Do While Not EOF(1)
datatodisplay = LineInput(1)
Loop
FileClose(1)
I would like to know how I can read the file line by line and then add all results into an array list.
