Opening/writing To A Text File In ASP.NET?
Mar 12, 2009
I want to write some stats to a text file every time a person loads a page. But every once in awhile I am getting at 'Could Not Open File, Already in use' type of error. I can not 100% replicate this error it is very erratic. My code is
Public Sub WriteStats(ByVal ad_id As Integer)
Dim ad_date As String = Now.Year & Now.Month
Dim FILENAME As String = Server.MapPath("text/BoxedAds.txt")
[Code]....
how can I lock and unlock the file so I stop getting the erratic errors?

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.

I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()
[CODE]...
The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.

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.
Private Sub facSubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles facSubmitButton.Click
Dim facultyRecord As String = "C:\Documents and Settings\All Users\Desktop\teeny.txt"

When using .write method the string will be stored at the end of the text file. Is there a method that adds them on top? If not, how can I get this done without using too much memory and processor time?

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 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.

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).
