Please, maybe this time? :)
In the CopyNode function, can someone edit it so it returns the correct node but also saves the .text of the source to a file.
It would be ideal if this code sample could be re-coded for only one treeview and to output the .text to a file.
The amount of information that I have in the source treeview is too much to copy to another without the ability to destroy the original which I can't figure out either.
I've been trying for 3 months and would appreciate a little help with this one.
The time it takes to do any of these tasks is irrelevant (it takes 30 seconds to populate this treeview now), it can be tuned. I need one of two scenarios...
1. Copy original to another TreeView while destroying the original making sure that what is in the original is copied to the destination alphabetically by Root.
2. Copy original to file using same scenario as above.
Neither scenario should copy by index, as that will not fit the file format.
TIA
Code:
Sub CopyTreeView(objTVSrc As TreeView, objTVDest As TreeView)
'Copies the source treeview to a destination
'treeview. Assumes that both treeviews use the
'same (or identical) Imagelists.
Dim nodeRoot As Node
objTVDest.Nodes.Clear
For Each nodeRoot In objTVSrc.Nodes
If (nodeRoot.Parent Is Nothing) Then
Call CopyTVParentNode(nodeRoot, objTVDest.Nodes)
End If
Next
End Sub
Private Sub CopyTVParentNode(nodeParent As Node, nodesDest As Nodes)
'Walks the specified source parent treeview node,
'and all of it's children nodes, adding them to the
'specified destination Nodes collection.
'
'nodeParent: parent node to walk and copy from
'nodesDest : destination Nodes collection to copy to
Dim nodeDummy As Node
Dim nodeChild As Node
'First add the parent node to the destination nodes collection.
Set nodeDummy = CopyNode(nodeParent, nodesDest)
'Get the current parent node's first child
Set nodeChild = nodeParent.Child
'Now walk through the current parent node's children
'appending the current child node's text to the passed string
Do While Not (nodeChild Is Nothing)
'If the current child node has it's own children...
If nodeChild.Children Then
'Recursively call this proc copying all of it's children
'(it becomes the new parent node)
Call CopyTVParentNode(nodeChild, nodesDest)
Else
'Add the child node to the destination nodes collection.
Set nodeDummy = CopyNode(nodeChild, nodesDest)
End If
'Get the current child node's next sibling
Set nodeChild = nodeChild.Next
Loop
End Sub
Private Function CopyNode(nodeSrc As Node, nodesDest As Nodes) As Node
With nodeSrc
If (.Parent Is Nothing) Then 'Root node
Set CopyNode = nodesDest.Add(, , _
.Key, .Text, _
.Image, .SelectedImage)
CopyNode.Expanded = True
Else 'Child node
Set CopyNode = nodesDest.Add(.Parent.Index, _
tvwChild, _
.Key, .Text, _
.Image, .SelectedImage)
CopyNode.Expanded = True
End If
End With
End Function
