I used PSET to set an image into a picturebox. But the image disappears if i minimize the picturebox or cover the pixels with another application.

how do i use pset and have the pixels stay in the picturebox?

when using pset, i passed a 16-bit value in as the pixel value.
it comes out all in shades of red.

how do i display this 16-bit image in grayscale instead ?

please advise.....
