Thanks for your time!

Dear Adrian,

Thanks for your reply!

Moreover, I would like to switching the window, graphic,... as well, currently if I'm not wrong, I see that we can just select one direction at a compile time, can we do it on run time? Please guide and correct me, if I am wrong!

Thanks for your time!
