Hello,

Please try executing the following code:

Code: Select all

uses OLEDBAccess;

procedure TForm1.Button1Click(Sender: TObject);
var
  er: EMSError;
  ts: string;
  i: integer;
begin
  try
    UniConnection1.Open;
  except
    on E: EUniError do begin
      er := EMSError(E.InnerError);
      ts := '';
      for i := 0 to er.ErrorCount - 1 do
        ts := ts + 'Message: ' + er.Message + '; ErrorCode: ' + IntToStr(er.Errors[i].ErrorCode) + '; OLEDBErrorCode: ' + IntToStr(er.Errors[i].OLEDBErrorCode) + #13#10;
      ShowMessage(ts);
    end;
  end;
end;

, and specify the exact message that the ShowMessage function will show you.
