This writes a line. As it says. So, instead, just write the text, not a line, and add a tab after it.

That will only work for pdf files and only if the extension is lowercased. The better thing to do would be to replace this:

Dim posn As Integer, i As Integer
Dim fName As String

posn = 0
'find the position of the last "\" character in filename
For i = 1 To Len(flname)
    If (Mid(flname, i, 1) = "\") Then posn = i
Next i
fName = Microsoft.VisualBasic.Strings.Right(flname, Len(flname) - posn)

with this:

fName = System.IO.Path.GetFilenameWithoutExtension(flname)

Then you will be guaranteed to never get the extension no matter what it is. Also, you can do without the extra temporary variable here:

Dim words As String = fName
Dim split As String() = words.Split(New [Char]() {" "c, ","c, "."c, ":"c, "_"c, "-"c})

because calling Split (or any other method) on a string does not change the original string.

but it did not when i repet the code for the other textboxs

'Save Settings Button
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Settings.SaveSet = TextBox3.Text
        Settings.SaveSet = TextBox4.Text
        Settings.SaveSet = TextBox5.Text
        Settings.SaveSet = TextBox6.Text
        Settings.SaveSet = TextBox7.Text
        Settings.SaveSet = TextBox8.Text
       
        Settings.Save()
    End Sub

'Load Setting Button
    Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
        TextBox3.Text = Settings.SaveSet
        TextBox4.Text = Settings.SaveSet
        TextBox5.Text = Settings.SaveSet
        TextBox6.Text = Settings.SaveSet
        TextBox7.Text = Settings.SaveSet
        TextBox8.Text = Settings.SaveSet

You have one variable and you set it to each textbox in turn. You need to create a variable for each textbox. You should buy a pretty basic book and work through it, if you don't understand that.

That's a simple coincidence. There may be better sources of programming information...

Subtract the time from DateTime.Now, to know how much time has ellapsed, in the form of a TimeSpan.

I don't see how this code would compile, is that really your code ? What is time, is it a string ? If it's a string, you've lost half the battle.

you can use datediff also but timespan is better option depends on the your desired results

try to look at cheat sheets also just for a quick reference , u can also Google cheat sheets
here is one of the reference

http://www.addedbytes.com/cheat-sheets/sql-server-cheat-sheet[^]

T = DateDiff("n", (T1), (T2))
T = TimeSpan.Compare(t1, t2)

numbrix puzzle

I have to design, write and test a vb program to help the user solve the "Numbrix" puzzle.

The user should have the capability to "undo" a number of steps taken in order to take another path it he current path is unworkable

so far I had this, I am able to crate a dynamic array of text boxes and load a from

Imports System.IO
Imports System.Math

Public Class Form1

    Structure rect
        Dim rec(,) As TextBox, val(,) As Byte, yy(,,) As Boolean
        Sub disp(ByVal a As Integer, ByVal b As Integer)
            Dim st As String = ""
            For i As Integer = 1 To 9
                If yy(a, b, i) Then st &= i.ToString

            Next
            rec(a, b).Text = st
        End Sub

        Sub comp(ByVal a As Integer, ByVal b As Integer)
            Dim i, j, cnt As Byte
            For i = 1 To 9
                If yy(a, b, i) Then
                    cnt = CByte(cnt + 1)
                    j = i

                End If
            Next
            If cnt = 1 Then val(a, b) = j
        End Sub

Please use PRE tags (as the forum guidelines dictate) so formatting gets preserved, lines get indented, and code becomes readable.

If this is a reply to me, why did you reply to yourself ?

You seem to be asking us to do your homework. I'm not even sure what point you're stuck on, just that you posted a lot of code. If you have a specific question, you can ask it, posting relevant code. We are not going to do your homework for you tho, you will not learn that way
