Graphical Techniques in QB

How to calculate the size of a graphic array
faq314-3254
Posted: 2 Mar 03

     Let's face it, arrays take up a lot of memory, and kilobytes, but if you want a decent program, then you need to use graphics.  To make decent graphic animations, you need arrays.  So how can you calculate the size of the array?  It is quite simple: arraysize = (xlength*ylength)-1.
So if your graphic is five pixels by five pixels, then your array needs to be 24 in length: array(24).
