Common Dialogue Screen Position

I am using the API method as described by John Percival on the vb-search site. I want to position the common dialogue box in the center of the screen as opposed to the top left corner of the screen. Does anyone know of a parameter to allow me to accomplish this goal? How can I control where the box appears on the screen?

Thanks,
Brian

theres an example of how to centre one of these boxes on this site.....

Thanks a ton, the information on that site was truly helpful!
