Finally the code is working BUT
The load function can not work because of this line in code
" //fl_register_images();" When i keep it , it gives me 23 errors
Can i changed it or do somethingelse to not stick with this problem
also i change the extension from cxx to cpp ?? but i'd like to
know the diffece between both
ANY HELP ANY SUPPORT GUYS
