over Network Database

Asked by: jimyX

hi experts;
i'm trying to connect 2 programs (client and server) via (socketconnection, ClientDataSet and DataSetProvider - with MS Access database).
i connected them togather successfuly, the Client program has login window, to use the client program you haveto enter username and password and the client will send the entered data to the server and the server program is matching the sent data (username and password) with the existent database.

in short word what i'm asking for is that :
how can i make the client read and write (insert, delete and edit) to the database via server program ?

I think this problem is best suited for use with SOAP, instead of plain socket connection

Why don't you migrate your database to MSSQL Server (MSDE) and you can much easyly connect to it remotely. A lot easyer that to ACCESS that's for sure. And this way having a database server holding the database you could succeed in your plans.

How does your server application process the login?

Usually the server application will parse the data from the client to identify commands... such as LOGIN,myname,mypassword ... similarly you can use this same concept to do something such as INSERT,field1,field2,field3 ... or UPDATE,field1,field2,field3 ...


Alternatively, you might want to check out FPiette's Midware components, which encapsulate all these. Using his components, you can create a procedure called Login in the server, and when the Client connects to it, it can call Login directly! Well, behind the scene, it actually scans for the word login and then pass the parameters to the correct procedure at the server side... Check out his components at http://www.overbyte.be/frame_index.html
