I've actually got 2 different questions, both concerning scrollbars...

First, on a Listview control (with gridlines and multiple columns), it works so that if the height of it is less than the height of the items in it, it automatically adds a vertical scroll bar...now how can i tell if there's *actually* a scrollbar on it?

Second, how can i determine (using any win32 module, really) the default width in pixels of a scrollbar on each seperate user's computer?  for instance, on mine, it's 16 pixels, but someone else's computer, it may be 5 pixels, or even like 32 pixels...how can i tell?

so, if anyone can answer my questions, or even point me in the right direction, it'd help me out a LOT.
