How To: Windows Service w/ remote clients, i.e SQL Server
Phil,
What about the client running in either a browser or Win32 app, that
interacts with the service? UDP may work for the broadcast but what if I
want to make property or method calls, much the same as you would with SQL
DMO? DCOM ( probably a dirty word in .Net ), Named Pipes ( named what? )?
What does .Net offer me that improves this type of architecture?
I've read .Net docs on Remoting, Sockets, and Web Services, all of which
lack comprehensive if any Visual Basic example code. My current release uses
sockets in VB6, but there's alot of data coersion to really get it to do the
trick. I would like to get rid of having to concern myself with things like
multiple messages in a single packet and the {*filter*} problem of never being
able to yield to the OS during the case where a socket receives more than
one message and does not complete before the next one comes in.
Thank you.
