Could this be done?

Everything is written in codes:

'CHECK IF "sIntroSequence" IS AVAILABLE IN TEXT FILE.
        Dim checkthevalue As String = My.Computer.FileSystem.ReadAllText("c:\test.txt")
        If checkthevalue.Contains("sIntroSequence") Then
 
            '"INTRO SEQUENCE" STRING IS AVAILABLE.
            'CHECK WHAT  COMES AFTER EQUALS SIGN.
            For Each k As String In IO.File.ReadAllLines("c:\test.txt")
                If k.Contains("sIntroSequence=BGS_LOGO.BIK") Then
            'IF IT IS "sIntroSequence=BGS_LOGO.BIK" THEN CHECKBOX18.CHECKED=TRUE.
                    Form2.CheckBox18.Checked = True
                Else
            'OTHERWISE SET CHECKBOX18.CHECKED=FALSE.
                    Form2.CheckBox18.Checked = False
                End If
            Next
 
        Else
            '"INTRO SEQUENCE" STRING IS NOT AVAILABLE IN THE TEXT.
            'SO CREATE IT...
            Dim lines() As String = System.IO.File.ReadAllLines("c:\test.txt")
            lines(10) &= vbNewLine & "sIntroSequence=" 'WRITE IT TO LINE10
            System.IO.File.WriteAllLines("c:\test.txt")
        End If

I can't seem to get the checkbox checked according to presence of a particular string in a text file. It looks like it should work but it doesn't. I don't know what i'm doing wrong.
