Determining memory size....

Is there a way of determining how many bytes of memory you are using for an object or image or control, etc.. programmatically?

Say I had an image that I loaded and had it's .hdc. Is there some way to use varptr() or something to find its location in memory and then determine how many bytes it's using?

Any help would be appreciated....

C

Probably with C or C++, but I don't think the amount of memory consumed by a single control on a VB form is something VB will return, although, at times, that would be handy. :)
