no doubt, because each shape have own text property. must iterate shapes on page. , iterate pages in document
, ms word's method dont works in ms visio. vba macro task

dim p page dim shp shape each p in vdoc.pages   each shp in p.shapes    shp.characters.text = replace(shp.characters.text, "table_name", screentitle & " master") next shp p.export(n) next p
