Description

OS: Win32
Compiler: VS 2010
File: highgui/src/window_w32.cpp
Function: icvCreateTrackbar

The range of the trackbar was being set using windows message type TBM_SETRANGE which combines the 'min' and 'max' of the range into a single DWORD. This leaves just 16 bits for each of the 'min' and 'max' range values, and leads no erroneous functioning of the trackbar in case of 'max' value being greater than 0xFFFF.

The fix (or better approach) is to use the windows message types TBM_SETRANGEMIN and TBM_SETRANGEMAX so that both the 'min' and 'max' values can have any 32 bit value.
