Using StreamReader To Read Lines From Textbox?
Sep 20, 2010I am using Visual Basic 2010 with Windows 7. My code is is follows:
Dim file as system.IO.StreamReader
file = My.Computer.FileSystem.OpenTextFileReader(C":financialsprogramcurrency.txt")
TextBox1.text=file.ReadLine()
file.Close
For some reason my program does not execute beyond the Dim statement and instead displays the form without text in TextBox1.

VS 2008 StreamReader Reading Certain Lines From Text File
Aug 15, 2010I 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]When I start debugging mode it does not display the text until I click onto the text box and it's displaying the first line of text in the file. How do I skip the first line of text and have it display the second line (or the 6th, 24, or whatever line I need to be displayed)?Then I can start working on learning to use streamwriter

View 4 Replies[2008] Keep To The Bottom Of A Rich Text Box And Read Changes In Txtfile
Mar 16, 20091) On one of my forms i have a richtextbox but whenever the programs ads something like richtextbox1.text = richtextbox1.text & "New Entry" The box goes back up to the top and you need to re-scroll down to the bottum. Is there anyway i can have it to always go to the bottum when something is changed instead of reverting back to the top. Because things are added almost every 1-2seconds until it gets to the point where you cant scroll down to read what was said before something new is added and it jumps back to the top.
If you dont know what i mean make a timer of 1 second that ads somethign to the textbox and youll see what im talking about.
2)Or better still is there anyway to get the program to recive new lines from the textbox. Basicly I have a textfile which is read by around 4-8 clients. I want each client to know what its read so it can process the textfile but i dont want it to say add something like ' to the start of every line its read and ignore all ' lines because then the other client will ignore it to. So what im looking for is a sub that will process the textfile and put any previous unread lines (previous unread lines that session [i.e since program restarted]) into a string array like newline(1)

Make A Text Box Show Bottom Lines?
Feb 5, 2010How can a text box control be programmatically made to scroll down and show the new lines appended at the bottom?
When data is appended to a multiline text box control, it always displays the first lines at the top, and the user has to scroll to the bottom to see the latest. When more data is appended, the control zooms right back to the top.
The vertical scroll is enabled, and so is multiline.
