Stop the searching under conditions ( Treeview )

Hi,
thanks to LaVolpe which sent me a great code to search the treeview I have another short question.
Can you take a look at the code, and tell me is there any possible to stop the searching if program will find node.text = STOP? after one click if TEST node has been found.

My treeview contains "the chapters" - groups of the nodes. Each of them has STOP node at the end. I wanna to stop the program if find position will get the last line of the chapter ( equal to STOP node ).

Is there any way?

Code:

Code:

---

Public Sub Command5_Click()

Dim NrLoops As Integer, iLastItem As Integer, iFirstItem As Integer
Dim i As Integer
Dim Searcher As String
Dim Searcher2 As String
Dim FindPos As Integer
Dim found As Boolean

Searcher = "TEST"

iLastItem = TreeView5.Nodes.Count
If TreeView5.SelectedItem Is Nothing Then ' start from top
    iFirstItem = 1
Else
    iFirstItem = TreeView5.SelectedItem.Index + 1 ' start on row after one selected
    If iFirstItem > iLastItem Then iFirstItem = 1 ' at bottom of list, start from top
End If

For NrLoops = 0 To 1
    For i = iFirstItem To iLastItem
        FindPos = InStr(1, TreeView5.Nodes(i).Text, Searcher, vbTextCompare)
       
        If FindPos <> 0 Then
            TreeView5.SetFocus
            Set TreeView5.SelectedItem = TreeView5.Nodes(i)
            TreeView5.SelectedItem.EnsureVisible
            found = True ' no longer needed. If FindPos=0 then found=false
          Exit For
        End If
    Next i
    If FindPos = 0 Then
        iLastItem = iFirstItem - 1
        iFirstItem = 1
    Else
        Exit For
    End If
Next NrLoops

If FindPos = 0 Then MsgBox ("Not found")


End Sub

I'd like to help, but I just don't understand.
1. You click the button & TEST is found
2. If it is found, you don't want the search function active any longer? If not, disable the button.

Maybe you can tell us in different words when the search function should be disabled and when it should not be disabled.
The search function you have exits when a match is found, it does not keep looping.
