    1. COI guess that was a bad example. I don't want to go the "net send" or "msg.exe" (in later Windows versions) route since they just show the message in a Windows alert box. Unless there's an easy way to listen and extract Windows alert messages received in Java, this will be a dead end for me.

    2. COThen provide a better example showing where this is "easily done in C#", or update your question. As others have mentioned, sending a message to a "Windows user ID" is inherently *not* cross-platform compatible, it is a Windows only solution. If you want a full blown instant messaging client, then use an existing open source instant messaging solution; Jabber, Rendezvous etc

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
