Back to the spider

It's almost time to go back to my spider that I created and make it self sufficient. I need to start populating my search db bigtime. I feel a little nervous because I haven't worked on that part of the project for a while. For the search engine part I am close to having a nice prototype. The last code I entered was:

if(!found)
{
row[i]=term2;
row[i-1]=1;
}
toboAdapter.Update(toboTable);

DataTable woes

For some reason I am unable to update a DataTable.

I've got a foreach(DataRow row in dataTable.Rows)

but if I assign row[whatever]=something;
and go row.AcceptChanges();

the changes don't get applied.
I think I may have to create a row object and do an Update. That's my initial hunch.
It worked in code above the foreach, but it was a little different there.
