Body
<p>Ok, so I have an application that - at start up - checks for other instances of the program using the Mutex "solution". So when I start the second instance of my program, I get a popup message telling me to ... well whatever.</p> <p>However, how do I handle it when I want to open a file in my already open instance, by double clicking the file in explorer? (Like Excel) I guess that the solution must be some sort of message handler between the "old" instance and the new, where the new tells the old to open file xxx. Or is there any other way?</p>

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.
