How can I Display Text Files? - vb.net

Question

I have a program that allows the user to complete test where all the user's scores are recorded in a seperate text file for each test. How would I display each text file so that for each test the scores can be displayed?

Answer 1

You can do this with a Linq query:
var scores = from file in System.IO.Directory.GetFiles(#"c:\path", "*.scores")
select GetScoreFromFile(System.IO.File.ReadAllLines(file));
with GetScoreFromFile:
private int GetScoreFromFile(string[] scoreLines)
{
// Some code to read the score from the file
}
To actually display the scores... You probably want to make something fancy (it sounds pretty game-like). If not, go with some sort of Grid control.

Answer 2

You can use an ini configuration file to do this. I have designed a VB class library which contains an ini File reader class which can be used to read and write to ini configuration files. Rather than save each score as a separate file, you can contain it in a single ini configuration file by separating them in sections.
You can download my class library here
Add a reference to the library in your project.
Here is an example of how to use it:
Dim ScoresReader As New Rodit.IniLib.IniParser
Public Sub ReadTestScores(ScoreFilePath As String)
ScoresReader = New Rodit.IniLib.IniParser 'Initializes new instance of class
ScoresReader.Load(ScoreFilePath) 'Loads scores file specified in subroutine args
For Each score As Rodit.IniLib.IniParser.IniSection In ScoresReader.Sections 'Each section in the ini file will represent a different user's score
'Here you can write whatever you want to do with the user's score
Next
End Sub
'Call example:
Protected Sub Form_Load(sender As Object, e As EventArgs) Handles Me.Load
ReadTestScores("C:\scores.ini")
End Sub
Ini file stucture:
[INIFILETEST] <-- Section
Name=Rodit
^ ^
| |
Key Value
By understanding this, it would be easy to read and write your scores using this method...
Hope this helped...
