Good afternoon all,
I have a question about Multi User applications in VB.Net.
On certain points in my application I want to give a message based on other users actions.
1 user clicks a button to print invoices from selected clients.
This means that other users can´t have the possibility to print invoices (or modifying the records that matches the invoice).
The main reason is that I have an invoice number wich I get from a database and you don't want this messes up.
So when user 2 click´s the same button I want my application to show a messagebox and tells the current user that user ... is processing the invoices and have to wait.
Is there somebody who can point me in the wright direction for this?
I think I have to use some sort of locking in a specific whay?
