(Visual FoxPro) Fetch 1st N Headers of Search ResultsCalls Search to get a message set, then downloads the 1st N messages in the message set. There are two equivalent ways of doing it: (1) iterate from 0 to N-1 and download each message individually, or (2) create a new message set that contains the 1st N messages and pass it to FetchHeaders. Both are demonstrated here. Note: This example requires Chilkat v11.0.0 or greater.
