The device is connected to wi-fi only. here are the codes: <pre><code>import java.util.Date; import java.util.Properties; import javax.activation.CommandMap; import javax.activation.DataHandler; import javax.activation.DataSource; import javax.activation.FileDataSource; import javax.activation.MailcapCommandMap; import javax.mail.BodyPart; import javax.mail.Multipart; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; public class GMailSender extends javax.mail.Authenticator { private String _user; private String _pass; private String[] _to; private String _from; private String _port; private String _sport; private String _host; private String _subject; private String _body; private boolean _auth; private boolean _debuggable; private Multipart _multipart; public GMailSender() { _host = "smtp.gmail.com"; // default smtp server _port = "465"; // default smtp port _sport = "465"; // default socketfactory port _user = ""; // username _pass = ""; // password _from = ""; // email sent from _subject = ""; // email subject _body = ""; // email body _debuggable = false; // debug mode on or off - default off _auth = true; // smtp authentication - default on _multipart = new MimeMultipart(); // There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
