LOOPING all node, sub node child and children item

Post by sal21 »

iterate all element in treeview....

My poor code:

Code: Select all

Private Sub Command2_Click()

Call AGGIORNA(Me.TreeView1)

End Sub
Private Sub AGGIORNA(TVTREE As TreeView)

    Dim N As Node, I As Integer, NOD As Node

    For Each N In TVTREE.Nodes
    
        If N.Image = 4 Then
        
        Debug.Print N.Text ' Is the item with arrow
        
        For Each NOD.Children In N.Children
         Debug.Print N.Text ' here i need to loop  IMPARATO ANTONIO, IMPARATO SALVATORE 
         Next
            
        End If
    Next
    '
End Sub
but when image=7, i need to get the value of node... tath contain this child....

example:
all item IMPARATO ANTONIO, IMPARATO SALVATORE have image=7, i need to get the value of item with arrow (have image=4)

Perhaps this?

Code: Select all

Private Sub AGGIORNA(TVTREE As TreeView)
    Dim N As Node, NOD As Node
    Dim I As Integer, M As Integer

    For Each N In TVTREE.Nodes
        If N.Image = 4 Then
            Debug.Print N.Text ' Is the item with arrow
            M = N.Children ' number of children
            Set NOD = N.Child
            For I = 1 To M
                Debug.Print NOD.Text ' here i need to loop  IMPARATO ANTONIO, IMPARATO SALVATORE
                Set NOD = NOD.Next
            Next I
        End If
    Next N
End Sub

Hans

Private Sub AGGIORNA(TVTREE As TreeView)

    Dim N As Node, NOD As Node
    Dim I As Integer, M As Integer

    For Each N In TVTREE.Nodes
        If N.Image = 4 Then
            'Debug.Print N.Text 'CAMERA
            M = N.Children  'NUMERO OSPITI NELLA CAMERA
            Set NOD = N.Child
            For I = 1 To M
                Set NOD = NOD.Next
                ReDim Preserve STROUT(R) As String
                STROUT(R) = N.Text & "|" & NOD.Text
                R = R + 1
                'Debug.Print NOD.Text 'OSPITI
            Next I
        End If
    Next N
    '
End Sub
error in STROUT(R) = N.Text & "|" & NOD.Text

note:
R is a public integer Dim

What is the error message?
And what is the value of R when the error occurs?

Do you have Option Base 1 at the top of the module? If so, insert the line

Code: Select all

    R = 1
above For Each N In TVTREE.Nodes.
