If the first line segment in the callout named "co1" has a fixed length, this example specifies that the length of the first line segment in the callout named "co2" will also be fixed at that length. For the example to work, both callouts must have multiple-segment lines.
Set myDocument = ActivePresentation.Slides(1)
With myDocument.Shapes
With .Item("co1").Callout
If Not .AutoLength Then len1 = .Length
End With
If len1 Then .Item("co2").Callout.CustomLength len1
End With
This example sets the title font size to 48 points if the title of slide two contains more than five characters, or it sets the font size to 72 points if the title has five or fewer characters.
Set myDocument = ActivePresentation.Slides(2)
With myDocument.Shapes(1).TextFrame.TextRange
If .Length > 5 Then
.Font.Size = 48
Else
.Font.Size = 72
End If
End With
