VS 2008 Saving And Update Text File?
May 14, 2012
i am trying to do a text file to save some configurations. Basically when the application starts it will check if the text file is exist, if not it will create a new text file. Now i'm having a problem is when i try to append the newly created/exist text file, sometimes i need to press the 'save' button many times to update the text file.
Here is part of my When the form loads
Private Sub Config_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If My.Computer.FileSystem.FileExists("C: extfile.ini") = False Then
[Code].....

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

visual basic 2008
I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

Basically iv got a form, and the fields are
"Full Name":
"Amount Contributed in �":
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith
Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:
Public Class Form2
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged

have a tab delimited text file, which I'm reading into a datatable and showing in a grid.I see that I can't update the text file with any changes made to the data, using an UPDATE command. So how would I go about doing this?I could write out the datatable to a new text file, this is not a problem. But I'm only retrieving X records from the text file, so the datatable won't hold the entire text file.

I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.

the new program I'am developing will enable the user to customise form and text colour.hese settings are to be applied to all forms used throughout the System.The method breakdown is as follows:1. User selects colour of form and text through hovering over a rectangle object of relevant colour.2. That information is stored to a text file.3. As the system is accessed again at log on, the settings are applied to all forms.

I have a sign up sheet that I am creating for a project I'm working on and the sign up sheet works and I can enter all my data into the text fields and save the info but when I go to open the file again all the data is pushed into one text box and not in their own fields?
If there a trick in the SaveFileDialog that I can use to save each field to file then open them back in their own field?
Here's a screen shot of the before and after the program [URL]
And here is code behind the Save button [URL]

I want to save a string of text to a file every 1.4 seconds or so, and each day at midnight I want to create a new file for the days log data so I keep the file size down. The file stays open the whole time so that it is ready to accept data from several different forms which call a function (SaveToVoltsLogFile(str)), so I open it at module level like this:
Dim fsVlogStream As New FileStream(EVENT_LOG_PATH & VOLTS_LOG_FILENAME & DateString & ".ip", FileMode.Append, FileAccess.Write, FileShare.Read)
Dim swVlogWriter As New StreamWriter(fsVlogStream)
Now each time I call a function SaveToVoltsLogFile(str), the str data gets saved to the file:
Friend Sub SaveToVoltsLogFile(ByVal str As String)
swVlogWriter.WriteLine(str)
swVlogWriter.Flush()
End Sub
But by opening it this way, I cannot call a sub to close it and open a new file for the next day because putting the Dims into a sub means that the file is out of scope to other subs/functions, so my Save... sub won't work! So, what I think I need is a separate sub to open the file, another sub to close it, and another to write the str data. But how do I do this and keep the file in scope to all subs?

I have a form that contains a RichTextBox control that I have set to multiline. I also have a menu item that allows the user to save the contents of the RichTextBox as either a .rtf document or a .txt document. Here's the code I'm using so far:
If sfdSaveTextFile.ShowDialog() = DialogResult.OK Then
m_strDocFileLocation = sfdSaveTextFile.FileName
m_strDocFileExtension = System.IO.Path.GetExtension(m_strDocFileLocation)
[Code]....
into the RichTextBox control (rtb) then saves as a text file this would save the text file like: "TempTemp"
Is there any way to write to the text file with line feeds included?

A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
I have tried several solutions:
1) data.SaveToFile "/temp/"&filename, 2
Error: Object required: '????????????????????'
???
2) File.WriteAllBytes "/temp/"&filename, data
Error: Object required: 'File'
I have no idea how to import this, or the Server for MapPath. (Cue: what a noob!)
3)
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Dim BinaryStream
[Code]....
This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.
