True if the specified object is one of the built-in styles or caption labels in Word. Read-only Boolean.
Remarks
You can specify built-in styles across all languages by using the WdBuiltinStyle constants or within a language by using the style name for the language version of Word. For example, if you specify U.S. English in your Microsoft Office language settings, the following statements are equivalent:
ActiveDocument.Styles(wdStyleHeading1)
ActiveDocument.Styles("Heading 1")
Example
This example checks all the styles in the active document. When it finds a style that isn't built in, it displays the name of the style.
Dim styleLoop As Style
For Each styleLoop in ActiveDocument.Styles
If styleLoop.BuiltIn = False Then
Msgbox styleLoop.NameLocal
End If
Next styleLoop
This example checks all the caption labels that have been created in the application. When it finds a caption label that isn't built in, it displays the name of the label.
Dim clLoop As CaptionLabel
For Each clLoop in CaptionLabels
If clLoop.BuiltIn = False Then
Msgbox clLoop.Name
End If
Next clLoop
