Simulating Keypresses in game

Ok so I have not programmed any sort of hacks in more than 6 months and now that I just got back into it im trying to make a simple bot for Perfect World. It wasnt anything big just a chat spammer but the problem that I came across was that nothing that I wrote would work. I used SendInput, PostMessage and nothing not a single character showed up. Thinking it may be the game I decided to try it with Vindictus and the same problem occurred. To make sure that it wasnt both games, I downloaded Macro Maker and it works perfectly fine. Now that im trying to recreate my own bot, nothing seems to work. Any help?

You could try to push your text to the engine itself :O

The application you target is 32 bit, so you can still use 32 bit MS Detours.
Alternatively you can try keybd_event, which is deprecated but should still work fine.

Try hooking DirectInput and inject your own data into the keyboard buffer. (That is, if they use DirectInput.)

Key event.... or visual basic...

use DirectInput
