VS2017 Data lost after project restart

I have a project written in VB.Net. My updates to the SQL Server are working fine except when I restart my project all changes are lost. After a lot of searching I found that I have to change 'Copy to Output Directory' to 'Copy if Newer' or 'Do Not Copy' (depending which site I read) in the properties of the database in Solutions Explorer. I can change the Copy to Output in properties of the form but I don't have the database in my Solutions Explorer. Totally lost and confused. I am teaching myself from VBA to VB.Net.
Any help would be appreciated.

All of which changes (code changes, data changes, etc)?

No, just the data. Code changes are fine. I think I understand what is going on, I just don't know how to fix it. I think something is set to avoid multi-user conflict on data change. My project is for one user only so I don't have to worry about that.
How do you manipulate the data that is sent to the database?  Can you provide a code example of what is used?

OK. Lots cut out for brevity.

As an extra thought - the data in SSMS shows the changes, again until the project is restart
SSMS shows the data being modified until the project is restarted.  Does your database happen to be an included file in the project?

-saige-
That, I think is my problem. In Solution Explorer there isn't a database listed. They are there is the Sever Explorer.
What does your connection string in the App.config have?

-saige-
Catalog changes depending on me (programmer) or users. Either RascalsTest or Rascals

Public Sub ConOpen()
        conString = "Data Source=192.168.1.64,1433;Initial Catalog=" & Catalog & ";User ID=" & UserId & ";Password=" & Password
        Try
            connection = New SqlConnection With {.ConnectionString = conString}
            connection.Open()
        Catch ex As Exception
            MessageBox.Show("", ex.Message)
            connection.Close()
            End
        End Try

Nothing you have shown is out of the ordinary.  This might require a remote connection to diagnose.  I'll be available at about 4PM CST if another solution cannot be found.

-saige-
Mmm, might be a bit of a problem. I am in the Uk! Could do with a Time Lord.....
I am online and available if you still need assistance with this issue.

-saige-
Hi, sorry about the delay getting back to you but Microsoft decide it wanted to do updates.....!

I am ready if you are, what do you want me to do?
Answered via private session. Duration 00:00:20
Did the session not work for you?

-saige-
No it flashed up in Chrome then said you had left the session
Huh...  Interesting...  Let's try again, if it doesn't work, I can connect via TeamViewer.

-saige-
Same thing happened again. Never used TeamViewer

Everything works fine  if i do this:
        ' Create the UpdateCommand.
        sqlString = "UPDATE Data SET  PaidIn = @PMPaidIn WHERE DataID =@DiD"
        command = New SqlCommand(sqlString, connection)
        command.Parameters.Add("@DID", SqlDbType.Int).Value = DiD
        PMPaidIn = 5.55
        command.Parameters.Add("@PMPaidIn", SqlDbType.Decimal).Value = PMPaidIn

        adapter.UpdateCommand = command
        command.ExecuteNonQuery()
        'command.ExecuteReader()
        connection.Close()

Open in new window


but not if I do this:
        sqlString = "UPDATE Data SET  PaidIn = @PMPaidIn WHERE DataID =@DiD"
        command = New SqlCommand(sqlString, connection)
        command.Parameters.Add("@DID", SqlDbType.Int).Value = DiD
        'PMPaidIn = 5.55
        command.Parameters.Add("@PMPaidIn", SqlDbType.Decimal).Value = PMPaidIn

        adapter.UpdateCommand = command
        command.ExecuteNonQuery()
        connection.Close()

        adapter.Fill(dts)
        adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey

        DGVData.DataSource = dts.Tables(0)

        dts.Tables(0).Rows(5).Item("PaidIn") = dts.Tables(0).Rows(5).Item("PaidIn") + 5
        cmdBuilder = New SqlCommandBuilder(adapter)
        adapter.Update(dts)
