VBScript Requires Chilkat v11.7.0+

A PDF Label That Is Not on the Page: notFound or Ignore

See more PDF Text Replacement Examples

Demonstrates the "unmatchedValues" option. A label or placeholder given a value but not found on the selected pages is a problem with the reason notFound, which stops "apply", because a missing label usually means the wrong document or a typo in the label. With unmatchedValues "ignore" such a value is skipped and the rest is applied -- the right choice when one set of values serves several document layouts. VBScript
