Dear Imar,

I am reading your book <ASP.NET 2.0 Instant Results>. Much thanks to your working. However, I have a little problem about chapter 2. In ResourceDB.vb class, what is the effect on optional parameter ID in Function SaveResource? I can not understand it. Why need the ID parameter?
The following comments in ResourceDB.vb:
'add in the parameters: the surveyID,
'the question text, and the possible choices (A,B,C,or D)
What aim?
Thanks.

Hi there,

I am not 100% sure, as I didn't write that chapter.

From looking at the code, I think the idea is that you can use SaveResource to save new and existing items. When the ID param s Nothing, then a new item will be saved; otherwise, the item specified by the ID will be updated.

I don't see SaveResource called with the ID parameter filled in, so if you don't see an immediate need for it, I think you can safely delete it.

Cheers,

Imar
