controlling interpolation when scaling graphics

I'm working on an experimental image manipulation application and don't have a lot of experience in this area.

I'm trying to scale up (zoom in on) an image on the form *without* having VB automatically interpolate & soften it.
What I'm looking for is the Photoshop equivelent of setting image interpolation to 'Nearest Neighbor' vs. 'Bicubic'.

I've searched google groups and the MSDN library for an answer to this problem (Zoom, StretchBlt, etc), but can't turn
up a thing - hope someone here can help.

Thanks in advance.
