asked on

passing a value with stream reader AFTER a ";"

i have a textfile (table) that has the following values
1;1,2,
2;1,1,
3;2,2,
up to 250;...

what i need is to create a function that, reads the table, and if the user selected 3(or any other number), it  searches within the table (txt file) and passes the value for the selected number  AFTER the ";", (meaning for the example:3 value to pass: 2,2,).

i will use that function value to build another string...

i quite can't get it...

suggestions please

        If True Then
            Dim line As String
            Dim sr As New StreamReader(tableselected)
            Dim table As String = ""

            For x As Integer = 0 To 1000
                line = sr.ReadLine()
                If line Is Nothing Then 'if the file is over, exit the for loop
                    table = table.TrimEnd(","c)

                    Exit For
                End If

                Dim searchWithinThis As String = line
                Dim searchForThis As String = "0;" '= index & ";"

                'If index > 10 Then
                '    searchForThis = index & "0;"
                'End If

                'If index < 10 Then
                '    searchForThis = index & "00;"
                'End If

                Dim tableresult As Boolean = searchWithinThis.Contains(searchForThis)

                If tableresult = True Then
                    Dim range As String = line.Substring(0)
                    ' If index < 10 Then
                    table = table & line.Substring(2) 'line.StartsWith(";") 'line.Substring(0, 41) '& Chr(3)
                    'End If
                    '    If range > 10 Then
                    '    table = table & line.StartsWith(";") 'line.Substring(1, 41) '& Chr(3)
                    'End If
                End If
            Next x
            sr.Close()
return table

    Private Function GetValue(stm As IO.Stream, index As String) As String
        Dim sr As New IO.StreamReader(stm)
        Dim searchWhat = index & ";"
        Do While Not sr.EndOfStream
            Dim line = sr.ReadLine
            If line.StartsWith(searchWhat) Then
                Return line.Substring(searchWhat.Length)
            End If
        Loop
        Return String.Empty

hi ended up doing differently, used the SPLIT
below code:

            If tbline <> "" Then
                flds = tbline.Split(";")
            End If

            'set each line in the array
            sortplanline(i) = spline
            tableline(x) = tbline

            'PENDING define output of array
            If flds.Length > 0 Then
                ZIPCODE = get_zipSP(i, TBSPlan.Text)

                If ZIPCODE = "" = True Then Continue Do

                sptopass = flds(1) & ZIPCODE 

                If sptopass.Length > 40 = True Then
                    sptopass = Chr(2) & Strings.Left(sptopass, 39) & ".." '
