如何从任何已连接的计算机跨LAN更新Visual Studio App数据库

Question

I have created an application which utilises a database to store information , how do I now allow that information to be updated from any computer connected along the same LAN. so once someone entered and saves new information them all other databases in the same app will update .

    Private Sub MLGMain_Load(sender As Object, e As EventArgs) Handles MyBase.Load
            Timer1.Start()
    'how do i get MLGDatabaseDataSet to be a file path here'
            Me.LocationRecordTableAdapter.Fill(Me.MLGDatabaseDataSet.LocationRecord)

    End Sub


        Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        UPDATETIME = UPDATETIME + 1
        Label1.Text = UPDATETIME
        If UPDATETIME > 700 Then

            '---------------------------------------UPDATE DATABASE-----------------------------------------'

            LocationRecordDataGridView.Refresh()
            LocationRecordDataGridView.DataSource = Nothing
            LocationRecordDataGridView.DataSource = ("C:\Users\User\Documents\folder\MLGDatabase.sdf")
            Me.LocationRecordDataGridView.DataSource = LocationRecordBindingSource
            LocationRecordBindingSource.RemoveFilter()
            LocationRecordDataGridView.Refresh()
            LocationRecordDataGridView.Refresh()
            UPDATETIME = 0
        End If
End Sub

I don't have enough rep yet to just post a comment, but my first question is, if this is a LAN-based application, isn't everyone pulling from the same database? Once you update the database from one user, the database should be updated for everyone. Of course, if you've got a record source displayed, such as in a DataGridView, you may need to implement a timer to refresh your data source periodically. If you're using an RDBMS (SQL Server, PostgreSQL, MySQL, etc.), this should be pretty simple.

I guess a big part of the equation is going to depend on the type of database you're using, and where that database is actually located.
