Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:

I have made a dock bar program
So when I drag programs in I get this
But when I restart my program all the dragged in applications are gone.

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?
1.is it possible to save the database connection string to the textfile so that user would be able to know where the database is stored?
2. Any way to let the user decide where the database is stored? Since usually we, the programmer write the database connection string ourselves..

I feel like I missing an important step and the answer is stearing me right in the face...

View 1 RepliesI 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 think I'm over thinking this, but I'm not sure where to start.
Sub SaveDocument() Dim outputFile1 As StreamWriter 'Object variable
Try'Create File outputFile1 = File.CreateText(strFilename)

I basically have a program where people type in their username and password, and then once button1 is pressed the program takes you to a website and logs in for you. The whole point of this is to fast the process.

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.
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question.
2) How can I save data, Datagrid to Text file.
I found a code
Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter
Public Function ConnectCSV1(ByVal filetable As String) As DataSet
Dim dataSet As New DataSet
[Code] .....
I can load data with this code but I can't save.
My Text File must be like this:
#IP
127.0.0.1 localhost
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
[Code]....
I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

I am trying to make my application read data from a file. Then save the data back. However I keep getting an error which says the file is still open so cannot be edited. I also read that there is an issue with the streamreader and streamwriter do not close the program straight away. I was wondering if anyone had a way around this or any alternative ideas. Heres my code so far!

Is there anything in the .NET framework or is there some API for making this possible?
Essentially what I'm trying to do is to save the value of a string() to a cell in the datagrid view. The problem is that when I close the program and reopen it the changed value isn't there... It's not saving properly.
Here is my code.
Dim BOCHURSTOTAL As Double = ((BochurimBindingSource.Current("Give_To_Bochur_Quant") * (bochurpr)) + _
(BochurimBindingSource.Current("Reg_Quant") * (regularpr)) + _
(BochurimBindingSource.Current("Priv1_Quant") * (private1pr)) + _
(BochurimBindingSource.Current("Priv2_Quant") * (private2pr)) + _

I created a form with 4 textboxes, one date picker, time and combobox. Now the problem I have is that I want to save all the values in these boxes in a folder which depends on what is selected in the combobox.
Source:
vb.net
Private Sub ListBox1_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
[Code]....
The idea is that if I select 3 in the combobox, the files has to be saved in the folder 3. This folder is located on a server located in the LAN.
