Accessing/Referencing PictureBox content

[Naro25]

Hi all,

I'm trying to find out how you reference the contents of a picturebox so it
can be used.

For instance, My code is VB.Net which opens powerpoint with a blank slide.
Instead of referencing a fixed file to add to a slide i.e:
Const sPic = "C:\ *.jpg"

I basically need:
Const sPic = "Picturebox"

Any help with this mater would be extremely appreciated.

Regards,
