Hello All,

I have developed two Winform Application where one acts as an Admin and another as a Client. Well, i need a logic or an explanation for, whenever Client updates the data in his form it should notify the Admin app.

Basically Client App has a data entry form where he enters the data and it is stored remotely(remote database. Now Admin app should receive a notification stating so and so data is entered by the client.

Out of interest am learning C# myself but at intervals i get stuck without logic or explanation. It will very helpful if someone explains me the logic.

What I have tried:

I have not tried any code since am lacking the logic behind.
Hope am not breaking any CodeProject rules.
