I have an odd on here. I'm trying to turn on mouse tracking in windows, and I'm using this code: TRACKMOUSEEVENT tme; tme.cbSize = sizeof(tme); tme.dwFlags = TME_LEAVE; tme.hwndTrack = hWnd; TrackMouseEvent(&tme); This is pretty much what it says to do in MSDN, but VC++ 2005 is refusing to compile with this code, saying it doesn't recognise the TRACKMOUSEEVENT struct. Has this struct changed name or something? I've included winuser.h and windows.h, which MSDN says are the required headers for this, so I'm at a complete loss as to why it won't recognise it. Anyone come across his problem before?

That wasn't it :( Seemed like a good idea too.

That was it - thanks for your help.
