Paul,

The name of the control as it is seen in the designer is Control.ID.  Other
usefull id/name properties on a control object are:

* Control.ClientID - used to identify each control in the html when using
client side Javascript.
* Control.UniqueName - uniquely identifies the control on the server side.  
Used internally to identify nested controls.  Don't use the UniqueName in
clientside Javascripts.

Here is some sample code that recursively iterates through the Controls on a
web page.  The code is in C#, though.  I just relealized that you needed VB.  
Let me know if you would like the code in VB.

Hope this helps,
Jason Vermillion
