i created an Application build in MS Access 2010, this create Jobs Orders, I am using split database which let me keep the tables in the server and the Front end program in the Work Station. Now, the problem is i have 6 laptops with the same application, but when the go out to the field the Laptops disconnect from network. I NEED A WAY TO SYNC TABLES WITH THE JOBS DONE when laptops come back to the office and connect to the network again.
I am Syncing pressing a button that copy files to server, delete tables locally and then copy back from server the records, but i want to find a way to Sync automatic when laptops find the network.

You'll need to write some code to check connectivity (On Error Resume next when connecting to the back end tables and check for an Error) and then connect to another local table if offline. Then once back in the office that code can then connect as normal and then you can upload your Jobs. Bottom line is that it'll take some VBA to do this. I can't give you a solution in code but this is the gist of it.
If you know how to code in VBA then you can really just check for a Network Folder that will be there if you're on the network. If it's not there, then you can assume you're offline. Then you will need to write more code to deal with local tables rather than linked tables.
Dim fso As FileSystemObject
Set fso = New FileSystemObject
If fso.FolderExists("[Path to Network Folder]") Then
' I'm online
Else
' I'm offline
End If
