I am writing an application that must generate a plain Text file with fixed sized columns.my current code is:

IO.File.Delete(MyFilePath)

I am trying to get my program to write a .bat file to run, it writes the file fine but the file wont run properly as it needs to be encoded with ANSI but i don't know how to set it to write that. The code for this part so far:

If My.Computer.FileSystem.FileExists(".

I have a long UTF8 encoded text string. The actual values stored in the string are hexadecimal. I want to convert the encoding and save to a binary file.
Is there a simple encoding.convert or other method to do this with?
Basically the output is twice as large as it needs to be right now. The long way of doing it would be a routine to go through the string two characters at a time and convert to byte array and then .writeallbytes I guess. It seems there must be a simpler way of converting this?
I used WriteAllText to set the encoding for a text file. When I wrote it, everything worked out fine. However, strange characters or symbols appeared in some ofm y fields without my having typed it. why is this so? The encoding I'm using is UTF8. I used the WriteAllText to write the fields to file but did not use the ReadAllText to bring the data back into the fields or program.
View 2 Repliesi would like to ask is there anyway to read a txt file with UTF-8 encoding using streamreader or filestream. the txt file is contain some extended ASCII that makes me cannot read the characters properly. I hav tried Encoding.ASCII.GetString(Encoding.UTF8.GetBytes()) but still it return wrong character when it's reading extended ASCII code.
View 2 RepliesI am sending a DDE message to a client using System.Text.Encoding.ASCII.GetBytes(item) . However, before the message is actually sent, I would like to get the message coded where if the item="Ask" then item=Ask (string variable) and so on. The code is:
Protected Overrides Function OnRequest(ByVal conversation As DdeConversation, ByVal item As String, ByVal format As Integer) As RequestResult

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.
*I am to use a file named Colors.txt
This is my first post in the community. I am putting together a program that serves two functions:1. Takes input from TextBoxes and writes it to a text file.2. Takes the text from the text file and displays two specific strings of text in a MessageBox.This is the code for the button that writes the input to file.

View 5 RepliesI have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?

I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
I want to write a line into a text /.cfg file. the line is = name "ishtiak", i need a space between name & "ishtiak". the text "ishtiak" is loading from a textbox called textbox1. i don't want in the text box my name like this "ishtiak" it will be without "" like this ishtiak but in the text file it will add "" before & after my name.
so the question is: 1.how to add space between name & "ishtiak"? like this = name "ishtiak". 2.My textbox text will be ishtiak,but it will be written like this "ishtiak" [Code]
We have some information that we need to write (about 18KB) to a .txt file stored in one of our network drives. The file is re-written about once every 15 minutes but is read practically at least every second. We are currently using StreamWriter to write file.The file server is in remote location and the round trip ping varies from <1ms to 15ms.
The problem is, sometimes it takes as long as 6 seconds to write the contents to the file, which is definitely way too long even after we take consideration of the network speed. therefore, I am just wondering if there is any efficient way to write the file using VB.Net to improve the performance? Java has a very good tool named BufferedOutputStream, which unfortunately is not available in VB.Net (or I just have not found it).
Application log file have been created to monitor the process and following code has been used to write the log information into text file.

How would a person read a line of a text file by the number of the line. In other words, if I wanted to get the 3rd line of the file, how could I store that third line in a variable. While I'm at it, I might as well also ask how to do the opposite, or write text to a specific line (in this case, writing over the other information on the chosen line).

View 2 RepliesI am creating a fault tracker AKA issue tracker. It is going to be very simple in functionality. As of right now I am using a text file as a database for the end user to store current issues.
The reason for me using a text file is that I do not know much about database programming and I cannot find any simple examples in the same usage. My question is, is it really going to become a problem as more issues are added to this file and it becomes larger? I.E using up more resources, application getting slower etc?
If so, could anyone point me in the right direction to creating a simple database application. Most examples I have seen require ask to download their pre-made database. Although I would like for the program to create a database if one is not there.
