Simple coordinate question

Hi,
I have been trying to plot points in a picture box, the problem is the points coordinates are in Latitude (-40.33344) and Longitude (175.44544) and the picture box is only 500 x 500 pixels wide.

Is there a way to force the picturebox to use my extents or is the another object I should be using??

For instance I would like the picturebox to be :
175.10000,-40.100000 (top left)
175.90000, -41.00000 (bottom Right)

Cheers
RM

You could make your own control that has a picturebox on it that does the math.
