Get an array of strings containing nodes text

I want to have an array of strings that will always contain the text's of the children of the selected Node. If no node is selected the array should contain the text's of the root nodes....

hlp....

cheers

It's not a problem to do what you want except one thing. Once you select one node in a TreeView, you cannot have "No Nodes Selected", because some node will always be selected. So, my suggestion will be is to create a Root Node. Any way here is the code for the array. First you would have to create a variable (array) on general declaration of the Form. Then use this code on Node_Click event.

Complete Code:

Code:

---

Option Explicit

Private m_arrNodes() As String


Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node)
    Dim iIndex As Integer
    Dim i As Integer
   
   
    ReDim m_arrNodes(i)
    If Node.Children Then
        m_arrNodes(i) = Node.Child.Text
        iIndex = Node.Child.FirstSibling.Index
        Do Until iIndex > Node.Child.LastSibling.Index
            If iIndex <> TreeView1.Nodes(iIndex).LastSibling.Index Then
                i = i + 1
                ReDim Preserve m_arrNodes(i)
                m_arrNodes(i) = TreeView1.Nodes(iIndex).Next.Text
                iIndex = TreeView1.Nodes(iIndex).Next.Index
            Else
                iIndex = iIndex + 1
            End If
        Loop
    End If
End Sub

---

arrNodes will have Children of the currently selected node.

Kewl....

How could I port this to the trieview1_gotfocus
event?

I mean execute your code for the selected node as soon as the treeview gets the focus

Badaboom:

Code:

---


Private Sub TreeView1_GotFocus()
  Dim nodX As Node
  Set nodX = TreeView1.SelectedItem
Call TreeView1_NodeClick(nodX)
End Sub

---

Ok, I want m_arrnodes to fill itself with all the root nodes.. This should only happen when the program is loaded. So that the NodeClick code can take over as soon as the user starts working with the treeview..

How can I fill the array with the text's of the root Nodes ??

Sure! Copy this code to Form_Activate event:

Code:

---

Private Sub Form_Activate()
    Dim iIndex As Integer
    Dim i As Integer
   
    ReDim m_arrNodes(iIndex)
   
    For i = 1 To TreeView1.Nodes.Count
        If TreeView1.Nodes(i).Parent Is Nothing Then
            ReDim Preserve m_arrNodes(iIndex)
            m_arrNodes(iIndex) = TreeView1.Nodes(i)
            iIndex = iIndex + 1
        End If
    Next
End Sub

---

m_arrNodes now holds Root Nodes Text.
