Question

I have written a C# winforms application that connects to a MS SQL database, this connects over the LAN. I would like to create an application that can be run on a laptop/netbook and use the database over the internet. I have seen various ways suggested on how to do this, SOAP, asp or ASP.net script, even openeing the SQL port on the firewall. Can you please advise the best practice way of doing this, and ideally link to a tutorial?

thanks

Andy
