1. SQL Server Raising Events To Visual Basic Clients
Hello All,
I have a simple problem and would like to know the best, simplest
solution.
I have numerous VB 6.0 client applications accessing a SQL Server
database.
The database contains typical Accounts Recievables data, such as
Invoices, Credits, Payments, etc.
Every time an invoice is created and saved (by any of the various
users of the system), I would like all of the client applications (and
hence, users) to be NOTIFIED somehow of this new invoice. Also, I
would like the server to spit back to each client the "Total Sales For
Today."
BOTTOM LINE: I want the total sales to be spit back to each client in
[approximately] REAL TIME as the sales are being made!
What's the best way to do this?
One very simple way I can think of is stick a timer somewhere on my
main VB form and have it query the database, say, every 10 seconds to
check for updated data. However, this does not strike me as very
elegant or efficient, and seems like it would be very resource
intensive.
Can SQL Server fire some sort of an event that is broadcasted (and,
can be intercepted) by all client connections?
Eagerly awaited your response.
