the problem is that I don't know how to connect them via local network to our main SQL server PC, is it possible to connect my app to the main SQL server PC for database purposes without installing another SQL in other PC's?
I used module for my database.
and here's the code for my database
Public Function LINKNAME() As String
Return "Server= TRADEWELL\SQLEXPRESS; Database = Tradewell Database; Integrated Security = true"
