    1. CO-1 ohmy, this is the most overbloated piece of code - not only it's long but it introduces dependencies on COM components - a nightmare in its own right. This is what crashy slow and unportable apps are made of.

    2. COCertainly you're right, for csv, one may use yours but for Excel, do you think that you're solution is helping ? No other solution including yours ( so far ) has shown up that says how to covnert to Excel, which seemes to be also a part of the actual question. If the intetion is just to downlaod a simple csv file, yours is a part of an elegent solution !

    3. COmaybe you posted on the wrong question? your answer won't even work on a (shared) server or if you manage to make it work it won't be stable, see Microsoft's own recommendations on using Office API on a server.

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.
