I am working with the formula for writing information to a text file. I have a program with 4 text box's and 5 radio buttons. I need to the program to write all of the info from the 4 text box's that the user has entered and the radio button that the user has selected.

View 3 RepliesI want to create a little program with textboxes in it, that writes the contents of these textboxes to a file. It also needs to write some predefined lines to the files, even on the same line as where the contents of the textbox is.
Heres an example:
The file should look like this when you open it in notepad:
^1::
Send t Text from TextBox {Enter}
First I think I would need to do this:
Dim ioFile As New StreamWriter("scripting.ahk")
ioFile.WriteLine("^1::")
If I do the above it works.. But how can I write another line where the "Send t" and "{Enter}" gets written automaticly before and after the contents from the Textbox?
Their is a problem whenever I want to write something to a text file. Please see the attatchement to see what happens when I'm debugging. I've put the code for writing to file right at the end of the program.Here is some of the code which shows how the program writes to and reads from the file:
Option Explicit On
'Force all variables to be declared.

I 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'm outputting a number of variables to a text file and each field needs to be in a specific place.For example:I have a string that is varying in length, but will never be more than 5 characters. The string has to end on the 8th character of the line. Is there a way to write the string to ensure that the string ends at a specific place on the line, regardless of the length?

View 4 RepliesI have seen a few different ways of Reading/Writing Text files. What i am trying to achieve is a simple debug file in the most efficient way possible. Currently I have....
If System.IO.File.Exists(debugpath) = True Then
Dim Debugwriter As New System.IO.StreamWriter(debugpath, True)
Debugwriter.WriteLine(debugwrite)
Debugwriter.Close()
[code]....
1. Do I have to close and reopen the file each time I want to write to it.
2. In vbscript I would simply open the the file at the start of the script and close at the end is the same possible here.
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.

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 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.

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).

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).
