-> Here's the code I use in the custom htmlutil-msg I made for WMP:


->    // MY ADDITION - check for unread messages

->   if SearchMessageById(c, GetLastRead(c), msg) then
->     if msg.id > GetLastRead(c) then
->       // Last read was deleted, but there's a newer message
->       TemplateSetVariable("confnew", str(TRUE))
->     else  // Last read found, look for next
->       TemplateSetVariable("confnew", str(GetNextMessage(msg)))
->     end if
->   else  // Last read was deleted, can't find newer message
->     TemplateSetVariable("confnew", str(FALSE))
->   end if

->   // END ADDITION


Just a clarification.

The theory is that this code wouldn't slow down things too much more
than they are now. There are a maximum of 3 server calls (GetLastRead,
SearchMessageById, and GetNextMessage) in the code. The GetNextMessage
isn't called under all circumstances, so often there are only 2 server
calls.

From the way wcNav behaves I assume you're already doing two calls
(GetLastRead and GetHighMessageNumber), so it's really a maximum of one
extra call to the server. I'm not sure how much load SearchMessageById
and GetNextMessage generate compared to just GetHighMessageNumber, so
all things may not be equal, but it's still a pretty compact piece of
code.


I intentionally made this as compact as possible, with as few server
calls as possible. What do you think?
