well first of all you have to be sure that the game and trainer versions are the same.
second carefully read the readme that's posted with the trainer in RAR file if it's there any button to press on main menu before playing.
Make sure you press the right button, like Shift and A
THANKS ALL OF YOU! ITS WORKS NOW! BUT! there is one problem, when i open the trainer application where it says "C&C3 not found yet. PLEASE run game" then i open my game "C&C3" and i went to skirmish to try the cheats... When i tried like example "SHIFT-B" means increase money then i heard it says "Activated" and i look at the money BUT IT NEVER INCREASE?!?! then i quit my game "C&C3" and i went to look at the trainer application and it says "C&C3 IS READY!" ITS STILL THE SAME!!??! WHAT HAPPEN!?! PLS DO HELP ME!! THANKS ALOT GUYS!
