I've made a game with the old version DirectX, for example:
LPDIRECTDRAWSURFACE and LPDIRECTDRAW.
After that I changed my mind to update the game that uses newer DirectX for example: LPDIRECTDRAWSURFACE7 and LPDIRECTDRAW7.
but I got tons of errors after changing ddraw.h ddraw.lib and all the things related to LPDIRECTDRAWSURFACE, and LPDIRECTDRAW.
I don't know why, can anyone help me?
