I just had a small question regarding reading and writing a text file.I have a program that reads lines out of a text file and writes them out to a new version of the file, changing text in there (same amount of digits).But the new file it creates is smaller than the original file, although the contents looks the same.
I must read the file scan for value T250,T169,T168,T170,T176............which ever value start with T after the line"DETECT,ON". then i must sort these values so that it will be in acending order. Then i must write back that values in same text file after the line FMAT,2.. Now i can read the lines which contain T. Then i store that lines in array. My code shows error when i used sort methode to sort the array which i store in array.
This is my code
Dim filename As String = strFileName Dim i As Long = 0
[CODE]...........
The sort methode give me this error "Overload resoulation failed because no accessible 'sort' can be called with these argument". Why it shows this error and how i write back the value after sort. Can i use append Text methde.
I've got another simple problem. I want a 'survey' form to show up whenever the user opens the program for the third time. I, of course, have the survey form built.[code]...
I'm writing an application for my Smartphone (OS is WM6 pro .NET Compact framework 3.5). Up till now i used VB6 so i'm pretty new to VB2008.
The application needs to store a set of items in a text file located on the device and retrieve them back. Since WM 6.0 doesn't support MS Access databases i have to work with the old fashion text files to store and retrieve my data. However since i'm new to VB2008 (and given the limitations of writing a smartphone application) I would llike to know how to write and read data to and from a text file.

I'm looking for some code to write /read an array to a text file in vb6.i have an array of a fixed size, and i need to write that into a text file, then later in another program i need to access that text file and write every element to a new array of the same size.the elements will be integer values, but "Long" datatypes. there will be no strings or anything else, just whole numbers.
Now I need to do is I need to read the file after the line DETECT, ON then if I find T250, T169, T176.....Txxx which ever line start with T. I must read and write that line back in between the line FMAT, 2 and DETECT,ON in my same text file.
I've been making a program whereby users names and numbers must be stored in external files. At the moment I can get the names to read and write to a file with these lines:
Imports System.IO Public Class frmDefaultMenu Private Sub frmDefaultMenu_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
Where each line has a name, a seaparator (,) and then the corresponding number.
When the program loads I would like it to be able to access that file, and store all the names into an array named ExistingUsers() and all the Numbers into an array called ExistingNumbers(), and then when a new name is added in the textbox, it is assigned the number "100" and placed at the end of the array, then when the application quits OR straight away, the external files are updated.

I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read: </head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td> After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.
