Do not post threads with generic subjects such as "zoom" or "delay". Instead, clearly state a phrase describing the problem as the thread's title. Do not flood the forum by posting the same question more than once. http://www.daniweb.com/forums/thread239687.html .
as adatapost rightly said, you should not create multiple threads for the same issue, and the forum rules do state that titles should be descriptive.
As for the zooming issue, i gave you a link in your previous thread to bob powell's GDI+ tutorials. You can use scale and translate transformations together to zoom an image. I used the tutorials there to get a grasp on transformations when i wanted to replicate a google earth style zooming map.
