You can also use SHAppBarMessage to get information about the system's taskbar—specifically, information about the taskbar's position. In SHELLFUN, the user can do this by choosing a menu option.
case IDM_TASKBAR:
{
APPBARDATA abd;
char buff [MAX_PATH];
memset (buff, `\0', sizeof (buff));
abd.cbSize = sizeof (APPBARDATA);
SHAppBarMessage (ABM_GETTASKBARPOS, &abd);
wsprintf (buff, "Left: %d, Right: %d, Top: %d, Bottom:
%d",
abd.rc.left, abd.rc.right, abd.rc.top, abd.rc.bottom);
// Update the multiline edit control.
SendMessage (hwndEdit, WM_SETTEXT, 0, (LPARAM)buff);
break;
}
The information returned from the call to SHAppBarMessage is displayed in the multiline edit control in the client area of the main SHELLFUN window, as shown in Figure 11-8.
