Array Duplicates

Hello again.

Let me get straight to the point.

I have a combobox, which I use to store the ComboText as well as the number of times that particular word(s) was clicked on inthat session. The code I use for the Combobox looks like:

Code:

---

    Private Sub cboSSCourse_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboSSCourse.SelectedIndexChanged

  If cboSSCourse.SelectedIndex > -1 Then 'if something selected

            iSS = cboSSCourse.SelectedIndex 'set = to sel index
            SSSubCount(iSS) += 1
            SSSubs(iSS) = cboSSCourse.Text & " " & CStr(SSSubCount(iSS)) & ";"
        End If

---

Then, I save this info into a text file with the following sub, when I exit the app:

Code:

---

    Private Sub SSWriteToFile(ByVal Path As String)
        Dim stream_writer As IO.StreamWriter
        Dim i As Integer

        ' Save the file.
        stream_writer = New IO.StreamWriter(Path, True)
        For i = 0 To SSSubs.Length - 1
            stream_writer.Write(SSSubs(i))
        Next
        stream_writer.Close()
    End Sub

---

This produces a Text file that looks like this:

Code:

---

ASP 2 Advanced 2;Corel Draw 10 Foundation 1;Dreamweaver Advanced 1;Business Finance 1;Director Foundation 1;Excel 2000 Advanced 1;ASP 2 Advanced 5;Dreamweaver Advanced 1

---

This works perfectly.

Now, what I need to do is to obtain a list of all the duplicates, alongwith their associated "click times" (which is the number next to the text, before the semi colon)

So, I did this:

Code:

---

    Private Sub SSGetSubFileInfo(ByVal Path As String)
        Dim stream_reader As IO.StreamReader
        Dim i As Integer
        'Dim j As Integer

        stream_reader = New StreamReader(Path, True)
        SSubText = stream_reader.ReadToEnd().Split(";")

        stream_reader.Close()
        ReDim SSFileSub(SSubText.Length - 1)
        ReDim SSFileCount(SSubText.Length - 1)

        For i = 0 To SSubText.Length - 1
            SSFileSub(i) = SSubText(i).Substring(0, SSubText(i).LastIndexOf(" "))
            SSFileCount(i) = SSubText(i).Substring(SSubText(i).LastIndexOf(" "), 2)

            If SSOrganiseList(SSFileSub) Then
                Console.WriteLine(SSFileSub(i))
                Console.WriteLine(SSFileCount(SSDup(i)))
            End If
        Next

    End Sub

---

This sub gets all the items within the textfile, and calls this function (to check for duplicates):

Code:

---

    Private Function SSOrganiseList(ByVal arr As Array) As Boolean

        ReDim SSDup(arr.Length - 1)
        For i As Integer = 0 To arr.Length - 1
            If Not arr(i) Is Nothing Then
                Dim l As Integer = Array.LastIndexOf(arr, arr(i))

                If l <> i Then
                    '          SSDupsFound += 1
                    SSDup(i) = i
                    '  SSDup2 = l
                    Return True
                    ' Return SSDupsFound
                End If
            End If
        Next
        Return False

    End Function

---

The problem is, once it has found a duplicate item, it stops counting.
What I'm trying to say is, it finds ASP 2 Advanced as a duplicate, with its "click time", it finds Dreamweaver Advanced as a duplicate, but doesn't find its "click time"

I need to find the items, then add together all their respected click times, for example:
ASP 2 Advanced has 5, then 2
So the total must be 7
Dreamweaver Advanced has 1 and 1 so the total must be 2

Any ideas on how I can achieve this?

Can anyone help with an idea?

If you use return inside your loop the loop will stop as the return is executed.
you need to add a boolean flag to indicate if duplicates where found... something like

Code:

---

Private Function SSOrganiseList(ByVal arr As Array) As Boolean

        Dim SSDup(arr.Length - 1)
        DIm Found as Boolean

        For i As Integer = 0 To arr.Length - 1
            If Not arr(i) Is Nothing Then
                Dim l As Integer = Array.LastIndexOf(arr, arr(i))

                If l <> i Then
                    SSDup(i) = i
                    Found = True
              End If
            End If
        Next
        Return Found
    End Function

OK, thanx Dnereb.
I have now replaced the Function with Sub.

I did this in there (it's basicall the same still):

Code:

---

Private Sub SSOrganiseList(ByVal arr As Array)

        ReDim SSDup(arr.Length - 1)
        For i As Integer = 0 To arr.Length - 1
            If Not arr(i) Is Nothing Then
                Dim l As Integer = Array.LastIndexOf(arr, arr(i))

                If l <> i Then
                      SSDup(i) = l
                                   
                End If
            End If
        Next
End Sub

  Private Sub SSGetSubFileInfo(ByVal Path As String)
        Dim stream_reader As IO.StreamReader
        Dim i As Integer
        'Dim j As Integer

        stream_reader = New StreamReader(Path, True)
        SSubText = stream_reader.ReadToEnd().Split(";")

        stream_reader.Close()
        ReDim SSFileSub(SSubText.Length - 1)
        ReDim SSFileCount(SSubText.Length - 1)

        For i = 0 To SSubText.Length - 1
            SSFileSub(i) = SSubText(i).Substring(0, SSubText(i).LastIndexOf(" "))
            SSFileCount(i) = SSubText(i).Substring(SSubText(i).LastIndexOf(" "), 2)

            SSOrganiseList(SSFileSub)
            Console.WriteLine(SSFileSub(SSDup(i)))
            Console.WriteLine(SSFileCount(SSDup(SSDup(i))))

        Next

    End Sub

---

Now, it returns:

Code:

---

ASP 2 Advanced
2
ASP 2 Advanced
2
ASP 2 Advanced
2
ASP 2 Advanced
2
ASP 2 Advanced
2
ASP 2 Advanced
2
ASP 2 Advanced
5
ASP 2 Advanced
5

I can see it does get the associated numbers, but only for the one duplicated entry, not the secondone which is Dreamweaver.
