Hi, My code uses the WM_LBUTTONDOWN events to perform picking tests. How would I go about activating the mousewheel? I tried WM_MOUSEWHEEL but I get an unrecongised variable error. MSDN doen't recommend much..... does anyone else use this? Thanks Simon

try this

#ifndef WM_MOUSEWHEEL
#define WM_MOUSEWHEEL 0x020A
#endif

You need to define the 'target version'

#define WINVER 0x0501
#define _WIN32_WINNT 0x0501
#include <windows.h>

(If you have a reasonable recent Platform SDK, of course.)
