I'm seeing "warning: it is not possible to determine that this content came from a trustworthy source" when copying tables from one database to another, e.g.
Dim tbl As TableDef
For Each tbl In CurrentDb.TableDefs
If Left(tbl.Name, 4) <> "MSys" Then
DoCmd.TransferDatabase acExport, "Microsoft Access", NewFileName, acTable, tbl.Name, tbl.Name, False
The error msg is really annoying and pops up for each and every object transferred! Any suggestions or workarounds?
