you can find a sample of intra-site module that does not use Nolics (it uses SqlDataSource controls) here :Sitefinity intra-site modules : The Unbearable Lightness of Development

They'll become your best friend very soon :).
By the way, the VB.NET version of above mentioned sample you can find here
