Ric,

>In addition to the dataset, FillDataSet also wants an IDbCommand or string (SQL statement), which is what seems redundant, given that the SqlDataAdapter in my custom data access class already has the IDbCommand and TableMappings it needs (in the SelectCommand member) to fill the dataset.

In that case you can simply override your business object's CreateDataSet() method so it always instantiates an instance of your typed DataSet. For example:

protected override mmDataSet CreateDataSet()
{
	return new MyDataSet();
}

Note that you must make sure your strongly typed DataSet is subclassed from mmDataSet. Also, note that you CAN specify different SELECT commands for a typed DataSet...you can call one of the GetDataSet() overloads and pass a new SELECT statement that will retrieve different data into the typed DataSet.
