DiagramNodeChildren Collection
DiagramNode
A collection of DiagramNode objects that represents the child nodes in a diagram.
Using the DiagramNodeChildren collection
Use the Children property to return the nodes in a DiagramNodeChildren collection. Use the FirstChild property to access the first child node in a diagram. This example deletes the first child of the second node in the first diagram in the document. This example assumes that the first shape in the active document is a diagram with at least two nodes, one with child nodes.
Sub DiagramNodeChild()
ActiveDocument.Shapes(1).Diagram.Nodes.Item(2) _
.Children.FirstChild.Delete
End Sub
