TDragon,
Thank you for reply. I didn't know it was a macro. This is a surprise for me. Because there is not a macro definition according to LCC, Mingw winuser.h header. Just a struct but has typedef for them to use ascii or wide char. Did you mean this. If not, point, wndclass, message etc must be macros is it? Did i understand wrong? How can i understand a windows class is a macro if it is not in header?
Regards
