How do you add a custom web part to your aspx page? EX: If I use the example from chapter 12 and change it to inherit from:
    Inherits System.Web.UI.WebControls.WebControl
then do a build I can add from the toolbar. However if I change it to:
    Inherits System.Web.UI.WebControls.WebParts.WebPart
And then do a build it does not show up in my toolbar.

An example in VB would be appreciated!

Thank you

Figured out my own question. If you want to add a custom webpart to your form you would use syntax similiar to:
<%@ Register Assembly="BookInfo" Namespace="BookInfo" TagPrefix="cc1" %>

You do not get the option to add from the toolbar when using custom webparts.
