We do not include this function because it needs the username and password for the database connection, and you may prefer to handle these differently from our simple example function. As a result, applications that preview correctly in <em>TQt Designer</em> will not run unless you implement your own database connections function.</p> <h3><a name="2"></a>Using <a href="tqdatatable.html">TQDataTable</a></h3> |
