    .Find Ignore case

    Code:
        Private Sub SortColour()
            Dim ObjectList As New List(Of String)
            For i As Integer = 1 To lstObjects.Items.Count - 1
                ObjectList.Add(lstObjects.Items(i).ToString)
            Next
    
            Dim L As Integer = rtbRoom.TextLength
            For Each word As String In ObjectList
                Dim lastindex = rtbRoom.Text.LastIndexOf(word)
                Dim index As Integer = 0
                While index < lastindex
                    rtbRoom.Find(word, index, L, RichTextBoxFinds.None)
                    rtbRoom.SelectionColor = Color.Lime
                    index = rtbRoom.Text.IndexOf(word, index) + 1
                End While
            Next
        End Sub
    HI, looking for some friendly advice.

    Can anyone please tell me how I can get the above code to be NOT case sensitive.

    I've tried all sorts but can't fathom it. Any help will be greatly appreciated.

    Convert one to Lowecase (or upper), and then do a compare.

    hi dglienna. Thanks for your reply.

    If you're saying what I think you are. Then I'm certain I've tried this already.

    At the moment, I have a workaround but I really don't like it. It's basically repeating the same code twice.

    UnEdited:
    Code:
         Private Sub SortColour()
            Dim ObjectList As New List(Of String)
            For i As Integer = 1 To lstObjects.Items.Count - 1
                ObjectList.Add(lstObjects.Items(i).ToString)
            Next
    
            Dim rb(4) As RichTextBox
            rb(1) = rtbAfterOpen
            rb(2) = rtbAfterTurn
            rb(3) = rtbExamine
            rb(4) = rtbOpenExamine
    
            For I = 1 To 4
                Dim L As Integer = rb(I).TextLength
                For Each word As String In ObjectList
                    Dim lastindex = rb(I).Text.LastIndexOf(word)
                    Dim index As Integer = 0
                    While index < lastindex
                        rb(I).Find(word, index, L, RichTextBoxFinds.None)
                        rb(I).SelectionColor = Color.Lime
                        index = rb(I).Text.IndexOf(word, index) + 1
                    End While
                Next
            Next
    
            For i As Integer = 1 To lstObjects.Items.Count - 1
                ObjectList.Add(lstObjects.Items(i).ToString.ToLower)
            Next
    
            For I = 1 To 4
                Dim L As Integer = rb(I).TextLength
                For Each word As String In ObjectList
                    Dim lastindex = rb(I).Text.LastIndexOf(word)
                    Dim index As Integer = 0
                    While index < lastindex
                        rb(I).Find(word.ToLower, index, L, RichTextBoxFinds.None)
                        rb(I).SelectionColor = Color.Lime
                        index = rb(I).Text.IndexOf(word, index) + 1
                    End While
                Next
            Next
        End Sub

    Edited for ease of reading
    Code:
         Private Sub SortColour()
         Dim ObjectList As New List(Of String)
            For i As Integer = 1 To lstObjects.Items.Count - 1
                ObjectList.Add(lstObjects.Items(i).ToString)
            Next
    
            Dim rb As RichTextBox = rtbTemp
    
            Dim L As Integer = rb.TextLength
            For Each word As String In ObjectList
                Dim lastindex = rb.Text.LastIndexOf(word)
                Dim index As Integer = 0
                While index < lastindex
                    rb.Find(word, index, L, RichTextBoxFinds.None)
                    rb.SelectionColor = Color.Lime
                    index = rb.Text.IndexOf(word, index) + 1
                End While
            Next
    
            'Repeat the above. Converting to lower. 
            For i As Integer = 1 To lstObjects.Items.Count - 1
                ObjectList.Add(lstObjects.Items(i).ToString.ToLower)
            Next
    
            For Each word As String In ObjectList
                Dim lastindex = rb.Text.LastIndexOf(word)
                Dim index As Integer = 0
                While index < lastindex
    
                    rb.Find(word.ToLower, index, L, RichTextBoxFinds.None)
                    rb.SelectionColor = Color.Lime
                    index = rb.Text.IndexOf(word, index) + 1
                End While
            Next
        End Sub
    I don't like "cheating" I think it's bad practice. So this is just a temporary fix until I can find the correct solution.
