Elaborate:there is no changes yet it accept changes and return a rows.
Further, by no changes you mean : dtMsg1 & dtFromDB have same data?

Here is the workaround. You can use HasChanges, before calling Get and Accept Changes as:

C#

if (ds.HasChanges(DataRowState.Modified))
{
  DataTable xdt = ds.Tables[i].GetChanges(DataRowState.Modified);
  if (xdt != null)
  {
    // ... work with the changes
    ds.Tables[i].AcceptChanges();
  }
}
