It doesn't show the numbers.
It looks like this!
source code
char TrackbarName[50];
/*sprintf( TrackbarName, "H_MIN", H_MIN);
sprintf( TrackbarName, "H_MAX", H_MAX);
sprintf( TrackbarName, "S_MIN", S_MIN);
sprintf( TrackbarName, "S_MAX", S_MAX);
sprintf( TrackbarName, "V_MIN", V_MIN);
sprintf( TrackbarName, "V_MAX", V_MAX);*/
sprintf( TrackbarName, "H_MIN", H_MIN);
sprintf( TrackbarName, "H_MAX", H_MAX);
sprintf( TrackbarName, "S_MIN", S_MIN);
sprintf( TrackbarName, "S_MAX", S_MAX);
sprintf( TrackbarName, "V_MIN", V_MIN);
sprintf( TrackbarName, "V_MAX", V_MAX);
//create trackbars and insert them into window
//3 parameters are: the address of the variable that is changing when the trackbar is moved(eg.H_LOW),
//the max value the trackbar can move (eg. H_HIGH),
//and the function that is called whenever the trackbar is moved(eg. on_trackbar)
// ----> ----> ---->
createTrackbar( "V_MAX", trackbarWindowName, &V_MAX, V_MAX, on_trackbar );
createTrackbar( "H_MAX", trackbarWindowName, &H_MAX, H_MAX, on_trackbar );
createTrackbar( "S_MAX", trackbarWindowName, &S_MAX, S_MAX, on_trackbar );

Plz helppppp....
