There's a big difference: you're setting the DataSource of the
control to itself. In the demo, there are two controls: and edit box
and an html box, and the edit box's DataSource is linked to the html
box, so that changes in the edit box are flushed to the html box when
the edit box loses focus.

Could you post a traceback of the error? Sounds like you're trying to
reference the html box before it has been created.

You could create a bizobj with a connection to the SQLite database,
and then bind the dHtmlBox control to the bizobj (DataSource), with
the DataField bound to the column name in the SQLite table.
