Macro to import styles

If you attach your new normal template to the documents, with the updatestyles on open option set, it should achieve what you require.

The following should do the job

    With ActiveDocument
        .UpdateStylesOnOpen = True
        .AttachedTemplate = "Normal"
        .UpdateStylesOnOpen = False
    End With

If this achieves what you require, with a little modification you can use this as a custom process with http://www.gmayor.com/document_batch_processes.htm i.e.

Function ApplyTemplate(oDoc As Document) As Boolean
    On Error GoTo Err_Handler
    With oDoc
        .UpdateStylesOnOpen = True
        .AttachedTemplate = "Normal"
        .UpdateStylesOnOpen = False
    End With
    ApplyTemplate = True
lbl_Exit:
    Exit Function
Err_Handler:
    ApplyTemplate = False
    Resume lbl_Exit
End Function

It did not work  for me. I created the macro as follows:

With ActiveDocument
  UpdateStylesOnOpen = True
  AttachedTemplate = "Normal"
  UpdateStylesOnOpen = False
End With

But when I run it, it does not import the styles. Am I missing somenting. I installed the macro in a document. Should I install it in normal.dot?
