Get a Mail-Merge Replacement String by Index

See more Email Object Examples

Demonstrates the Chilkat Email.GetReplaceString method, which returns the replacement string for the Nth previously-defined pattern/replacement pair (a mail-merge feature). The index is zero-based and corresponds to the same index used by GetReplacePattern. This example defines two pairs and prints each pattern with its replacement.
