Ok, ich habe es nun hinbekommen. So sieht es aus:
Dim application As Variant
Dim application1 As Variant
Dim ActiveDocument As Variant
Dim MasterDocument As Variant
Dim ActiveDocument1 As Variant
Dim b As Variant
Dim Selection As Variant
Set application = CreateObject("Word.Application")
Call application.documents.add( "e:\mietevorlage.doc" )
Set ActiveDocument = application.activedocument
application.visible = True
Set application1 = CreateObject("Word.Application")
Call application1.documents.add( "e:\miete.doc" )
Set ActiveDocument1 = application1.activedocument
application1.visible = True
Call ActiveDocument.Bookmarks("name_bookmark_1").Range.Copy
Call ActiveDocument1.Windows(1).Selection.Paste
Call ActiveDocument.Bookmarks("name_bookmark_2").Range.Copy
Call ActiveDocument1.Windows(1).Selection.Paste
Call ActiveDocument.Close
Call application.Quit
Danke Dir Christian nochmal für das Anschubsen in die richtige Richtung
