WebService for Intranet Win app through HTTP ?
Currently, i have a database windows application and it's attached to a card reader device on client computer...
in intranet (network), it's easy to maintain this client server windows application..
now, the SQL Server Database will be in headoffice,
meanwhile the client application will be in different city,
and we have to access the SQL Server through HTTP (internet connection)..
the client still has a reader device (+DLL) attached.
Logically, we should use ASP .NET,
but it does not solve the device reader issue on client side.
i tried to find how to call this DLL, and trigger the event,
and execute the event...blank..i already ask some forums including this wrox, but no satisfied answers....
then i think of this design :
a. for client side in different city,
we still use windows application , so it's no problem with the reader device DLL stuff...
b. the only issue is how we can send and receive SQL data through
HTTP (internet connection) to SQL Server in headoffice (different city)...
if i can solve this issue that it works fine...
Can we use web service to do this design ??
so we only need to use web service to query, insert, update, delete SQL data through internet connection,
we do not use ASP .NET web application...
is that possible ???
