Terve.

Lämmitellään vähän uudestaan tätä kun toi edellinen keskustelu oli jo niin vanha
että ei pystyny lisäämään viestejä...

Siispä... Tässä ois toi Nea:n tekemä sarakejako koodi.

Mutta jos tossa teksti tiedostossa on tyhjä rivi jossain välissä tai lopussa,
se heittää virhe ilmoituksen:

Index was outside the bounds of the array.

Mitenköhän tosta pääsis eroon?

Private Structure ScoreStruct
   Dim name As String
   Dim value As Integer
End Structure

Dim Scores() As ScoreStruct

Sub Button1_Click(sender As Object, e As EventArgs)

   FileOpen(1, "C:\Scores.txt", OpenMode.Input)
   Dim strLines() As string = _
   Split(InputString(1, _
   CType(LOF(1), Integer)), Environment.NewLine)
   FileClose(1)

   Redim Scores(strLines.length - 1)
   Dim temp(strLines.length - 1) As integer
   Dim slen As Integer

   For i As integer = 0 To strLines.Length - 1

      Dim helpArray() As string = Split(strLines(i), " ")
      Scores(i).name = helpArray(0)

      If slen < (helpArray(0).Length + _
      helpArray(1).ToString.Length) Then
         slen = helpArray(0).Length + _
         helpArray(1).ToString.Length
      End If

      Scores(i).value = CType(helpArray(1), Integer)
      temp(i) = CType(helpArray(1), Integer)
      helpArray = Nothing

   Next

   strLines = Nothing

   Dim lstInt As New List(Of Integer)
   lstInt.AddRange(temp)
   temp = Nothing: lstInt.Sort
   listBox1.Font = New Font("Courier New", 8.25!, _
   FontStyle.Regular, GraphicsUnit.Point, CType(0,Byte))
   listBox1.Items.Clear
   listBox1.Sorted = False

   For i As integer = lstInt.count -1 To 0 Step -1

      For j As Integer = 0 To Scores.Length - 1

         If lstInt.Item(i) = Scores(j).value Then
              Dim thespace As String = "  "
              If slen > (Scores(j).name.Length _
                 + Scores(j).value.ToString.Length) Then
               Dim thelen As Integer = _
               slen - (Scores(j).name.Length _
               + Scores(j).value.ToString.Length)
               thespace += New String(CType(" ", Char), thelen)
              End If
              listBox1.Items.Add(Scores(j).name _
              & thespace & Ctype(Scores(j).value, String))
         End If

      Next j

   Next i

Yrität laittaa johonkin taulukkoon enemmän tavaraa kuin mahtuu.

jtha [27.02.2011 10:25:51]

#

Olen hoitanut tuon asian omissa ohjelmissa seuraavasti(pätkä koodia josta selvinnee idea):

For I = LBound(TuoteRivi) To UBound(TuoteRivi)
  List1(0).AddItem TuoteRivi(I).Koodi & TuoteRivi(I).Nimike
Next

Fontti on "Courier New", jotta merkit ottavat saman leveyden. Tämä on mielestäni yksinkertaisin ja tehokkain tapa varmistaa että sarakejako täsmää.

Joo ei mitään, jtha vastasikin ekaan postaukseen

#

Moi taas...!

Nyt rupee lähtee järki tän Listboxin kanssa...

Nyt on siis saatu sarakejaot toimimaan ja vaikka ois tyhjiä rivejäkin
tiedostossa homma toimii, mutta....

Jos listalla sattuu olemaan useampi sama "tulos" ni sitte tää menee sekasin..

Esimerkki.... ;)

(teksti tiedostossa on siis tulos lista...)

Sami 400
Kalle 355
Jussi 355
Ville 355
Teemu 300
Jari 200

Nytpä listaus Listboxissa on sitte vastaava...

Sami 400
Kalle 355
Jussi 355

Kalle 355
Jussi 355
Ville 355
Kalle 355

Eli se "tuplaa" ton listan niin monta kertaa ku sama tulos löytyy listalta...


Apuva!!!!!!!!!!

Nyt on sitten niin ikävä tilanne ku jengi on käynny lisäämässä pisteitään ohjelmaan ni nyt on 240 teksti tiedostoa joissa noita "tuplia" saattaa olla ;)

Oisko mitään ideaa kuinka sais ohjelman luuppaamaan läpi noi kaikki tiedostot.

Tiedostot on tyyliin...

W1L1.txt
W1L2.txt
W1L3.txt
jne.. (Angry Birdsin kenttiä ;D )

vähän Textboxii ja Openfiledialogiii.

Mutta sitte taitaa mennä vähän ohi topikin :)

Mulla on .lua tiedosto jokseenkin näin...

Level27 = {
    completed = true,
    birds = 3,
    score = 1,
    lowScore = 33390,

}
LevelP2_104 = {
    completed = true,
    birds = 4,
    score = 2,
    lowScore = 68650,

}
Level9 = {
    completed = true,
    birds = 1,
    score = 3,
    lowScore = 56130,

}
LevelP2_65 = {
    completed = true,
    birds = 2,
    score = 4,
    lowScore = 42490,

jne...

ja hakusanana on siis toi Level****.
mutta mä haluan siis saada ton score = "******" tiedon ittelleni johonkin, esim listboxii tai richtextboxii.

siis kun mä löydän tosta richtextboxit haluamani Levelin ni kuinka mä pystyn siirtyy 3 riviä alaspäin tossa richtextboxissa....
vai onko tähän olemassa joku helpompi konsti olemassa ettei tarttis loikkii noita rivejä(en oo kyllä keksiny mitää muutakaa konstia.)

Ok. vähän huono esimerkki, koska tää sitte pitäs käydä looppina läpi n. 240 levelin läpi...

No näillä mennää.... ;)
