Eber, thats a great question, so I fired up Reflector and looked at the SqlParameter constructor. The value of the SqlParameter class gets initialized to null, not DBNull.Value, which is what we want. I took a screenshot of reflector so you can take a look. http://codebetter.com/photos/ben.reichelt/images/136294/original.aspx Eric, I bet I would still manage to goof it :) Wheneve I have to code in VB, my mind always translates Nothing to null, so I bet I would still try it.

Nothing is the VB equivalent so the whole DBNull.Value thing is a bit easier to catch. Let the language wars begin! See, now you don’t run into this in VB because there is no “null”.
