SQL Server Requires Chilkat v11.7.0+

See more PDF Text Replacement Examples

Demonstrates the "pages" option, which limits the search for placeholders and labels to the given pages: "all" (the default), "first", "last", "odd", "even", or a list such as "1,3,5-9". The two-page order confirmation carries the same "Status:" label on both pages; the status is changed on page 2 only, then on both pages. SQL Server
