I am trying to read through a text file and pull out bits of information I need. I have it 1/2 working but need to figure out how to loop through it to get the other 1/2

Sample log file

'----------------------------------------------------------------------------------------------------------------

The 1st part "If WhichToon = 1 Then" works perfectly as the 1st line of code always has what I look for
thee 2nd part "If WhichToon = 2 Then" Doesn't
Right now I have it set to look at the 2nd line for toonname:companionname but it might be in the 3 or the 20th line [or anywhere in between, or not at all if there is no companion]

I've used things like If strArr(1).Contains(":") Then and it can see it [or not] depending on which line I manually tell it to look at and I have run it through a loop such as

IF NOT strArr(1).Contains(":") Then
Dim i 
For i = 0 to 20
ToonInfo = ReadSpecifiedLine(Label6.Text, i)
next

which does loop through it and I can see the output in my debug field but I can't "trap" it when it does find it.

Any ideas on how I might be able to do this in real basic methods?

I think you want something like this:

dim i as integer 

For i = 1 to 20
   ToonInfo = ReadSpecifiedLine(label6.Text, i)
   if Instr(ToonInfo, ":") <> 0  then
    'do what ever
    exit for
   end if
next

Instr searches for an instance of a string within a string if it finds the search string inside the string being searched it will return an integer value of the position within the search string in the string being searched. If not it will return a zero.
e.g.

Dim Works as string ="apple"
Dim Fruits as string  = "apple,pear,peach"
dim NotWork as string = "melon"
dim i, y as integer
i = Instr(Fruits, Works) 'i will equal 1
y = intr(Fruits, Works) 'y will equal 0 as "melon" is not in the Fruit string

I came up with a different method that seems to work ok. It isn't pretty but does get me what I needed to get

I ended up splitting it into 2 function

Public Function GetToonName()
        Dim ToonInfo As String = ReadSpecifiedLine(Label6.Text, 1)
        Dim str As String
        Dim strArr() As String
        Dim count As Integer
        str = ToonInfo
        strArr = str.Split(New Char() {"]"c})
        For count = 0 To strArr.Length - 1
            Try
                Dim strValue
                strValue = Replace(Replace(Replace(Regex.Replace(strArr(1), "\{.+?}]*?", ""), "@", ""), "[", ""), " ", "")
                If Label16.Text = "Loaded" Then
                    Label17.Text = strValue
                End If
            Catch Ex As Exception
                LogConsole.Text = LogConsole.Text & "It fucking errored " & Ex.Message
            End Try
        Next
        'Create Toons data dir
        Dim TLogDir As String = My.Computer.FileSystem.SpecialDirectories.MyDocuments & "\" & "Star Wars - The Old Republic\CombatLogs\ReaderFiles" & "\" & Label17.Text
        If Not My.Computer.FileSystem.DirectoryExists(TLogDir) Then
            My.Computer.FileSystem.CreateDirectory(TLogDir)
        End If

        Return 0
    End Function
    Public Function GetCompName()
        Dim strCompName As String = ""
        Dim logFileStream As New FileStream(Label6.Text, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)
        Try
            Using rdrFile As StreamReader = New StreamReader(logFileStream)
                Dim strCurrentLine As String = ""
                Do
                    strCurrentLine = rdrFile.ReadLine
                    'LogConsole.Text = LogConsole.Text & strCurrentLine
                    Dim TheCall = "@" & Label17.Text & ":"
                    'RichTextBox2.Text = TheCall
                    If strCurrentLine.Contains(TheCall) Then
                        'Store whole line into variable
                        strCompName = strCurrentLine

                        Exit Do
                    End If
                Loop Until strCurrentLine Is Nothing
            End Using 'rdrFile (closes file & disposes object)
        Catch Ex As Exception
            LogConsole.Text = Ex.Message
        End Try
        Dim TheCompLine = strCompName

        Dim str As String
        Dim strArr() As String
        Dim count As Integer
        str = TheCompLine
        strArr = str.Split(New Char() {"]"c})
        For count = 0 To strArr.Length - 1
            Try

                Dim strValue
                strValue = Replace(Replace(Replace(Regex.Replace(strArr(1), "\{.+?}]*?", ""), "@", ""), "[", ""), Label17.Text + ":", "")

                Label19.Text = strValue
            Catch Ex As Exception
                LogConsole.Text = Ex.Message
            End Try
        Next
        'Create Comp Data File
        Return 0
    End Function

like I said, it's not pretty :(
Instead of trying to loop 1 line at a time, I just read the whole file and get what I need that way

Tell me in English (not in code) what you want (not just the last part put the whole thing) and I'll see if we can come up with something simpler.
