Hi Guido,

What do you want to connect? The BdpConnection can act as Connection 
property for the SelectCommand, InsertCommand, DeleteCommand and/or 
UpdateCommand of the BdpDataAdapter, but you have to create an instance 
of these before you can assign their Connection property.

> 'Object reference not set to an instance of an object ' ERROR

Otherwise you might indeed get the above error (the BdpCommand is not 
yet assigned)

Just select the BdpDataAdapter (click on it) and then click on the 
"Configure DataAdapter" link at the bottom of the Object Inspector. This 
will start the BdpDataAdapter Configuation Dialog that you can use to 
create the Select, Insert, Update and Delete commands (just check the 
checkbox of the commands you want). Note that the BdpConnection 
component will automatically be selected as the Connection property 
value for all BdpCommands that you use here (if there are multiple 
available BdpConnection components you can use the drop-down combobox to 
select one).

For more info and a screenshot, see the "Configure Data Adapter" section 
of http://www.drbob42.com/examines/examin52.htm

Groetjes,
