expression.BreakForwardLink
expression Required. An expression that returns a TextFrame object.
Remarks
Applying this method to a shape in the middle of a chain of shapes with linked text frames will break the chain, leaving two sets of linked shapes. All of the text, however, will remain in the first series of linked shapes.
Example
This example creates a new publication, adds a chain of three linked text boxes to it, and then breaks the link after the second text box.
Sub BreakTextLink()
Dim shpTextbox1 As Shape
Dim shpTextbox2 As Shape
Dim shpTextbox3 As Shape
Set shpTextbox1 = ActiveDocument.Pages(1).Shapes.AddTextbox _
(Orientation:=msoTextOrientationHorizontal, _
Left:=72, Top:=36, Width:=72, Height:=36)
shpTextbox1.TextFrame.TextRange = "This is some text. " _
& "This is some more text. This is even more text. " _
& "And this is some more text and even more text."
Set shpTextbox2 = ActiveDocument.Pages(1).Shapes.AddTextbox _
(Orientation:=msoTextOrientationHorizontal, _
Left:=72, Top:=108, Width:=72, Height:=36)
Set shpTextbox3 = ActiveDocument.Pages(1).Shapes.AddTextbox _
(Orientation:=msoTextOrientationHorizontal, _
Left:=72, Top:=180, Width:=72, Height:=36)
shpTextbox1.TextFrame.NextLinkedTextFrame = shpTextbox2.TextFrame
shpTextbox2.TextFrame.NextLinkedTextFrame = shpTextbox3.TextFrame
MsgBox "Textboxes 1, 2, and 3 are linked."
shpTextbox2.TextFrame.BreakForwardLink
End Sub
