   insertion sort?
Public Class Form1    Dim Original(0 To 10) As Integer    Dim Sorted(0 To 10) As Integer    Dim FinalList As String    Dim n As Integer    Dim m As Integer    Dim pos As Integer    Dim f As Integer    Private Sub SortButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SortButton.Click   If TextBox1.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox2.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox3.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox4.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox5.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox6.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox7.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox8.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox9.Text = "" Then  MsgBox("Please enter a value in all the boxes")  Exit Sub   ElseIf TextBox10.Text = "" Then  MsgBox("Please enter a value in all the boxes") Exit Sub   End If   Original(1) = TextBox1.Text   Original(2) = TextBox2.Text   Original(3) = TextBox3.Text   Original(4) = TextBox4.Text   Original(5) = TextBox5.Text   Original(6) = TextBox6.Text   Original(7) = TextBox7.Text   Original(8) = TextBox8.Text   Original(9) = TextBox9.Text   Original(10) = TextBox10.Text   For n = 1 To 10  pos = n  For m = 1 To (n - 1) If Sorted(m) &gt; Original(n) Thenpos = mFor f = (n - 1) To m Step -1    Sorted(f + 1) = Sorted(f)Next fm = n End If  Next m  Sorted(pos) = Original(n)   Next n   FinalList = ""   For n = 1 To 10  FinalList = FinalList & Str(Sorted(n))  If n &lt; 10 Then FinalList = FinalList & ", "  Else FinalList = FinalList & "."  End If   Next n   SortedValuesLabel.Text = FinalList    End SubEnd Classwell, theres my code for my insertion sort which i did a few months back at school, but now i'm trying to add as many comments to it as i can, so in the future i can come back and understand it easily. The problem is, i have no idea of how it does what it does. i realise that it creates an unsorted and sorted 'pile' and goes through the list with each one checking where it fits in, but the teacher used his set code, so i have no idea what some of the variables mean at all.especially the f? if someone has the time to help me could you just explain segments of the code (or all of it if possible) in plain english? i've made a few other things but what makes me understand them is clever variable names, but these are just giving me a headache.thanks in advance for any help xbtw, i'm using visual basic and visual basic 2005 express edition, thanks xalso, one of the main things i can't understand besides the f, is what something - 1 is, i understand for n = 1 to 10 means the numbers 1-10 in the array (i think?) but how the hell does something go into minuses?anyways, thanks again for any help x(sorry Justin Rebuilt :))[Edited by - qprmanzz on February 2, 2008 7:00:53 PM]
  Edit the code and surround it with [ source lang="vb" ] [ /source ] only without all the spaces.   ;Dim num(100) As Integern = 100For pass = 2 To n    temp = num(pass)    slide = pass   While temp < num(slide - 1)   num(slide) = num(slide - 1)   slide = slide - 1    Wend    num(slide) = tempNext passFor i = 1 To nList1.AddItem num(i)Next iTry looking at that, it should make more sense.
