How to Change Lparam before calling CallNextHookEx()?

Thanks all for reply.. one thing is sure we cant modify by using
WH_KEYBOARD/WH_KEYBOARD_LL hook...
I am using WH_GETMESAGE hhok to capture and modify the character.By
Using wParam definitely we can modify keystrokes. By I wan to keenly
observe it using lParam. I am trying to do like this.


MSg *msg = (MSG*)lParam
if(msg->lParam == xx1Exxxx) // 1E is the scancode of character 'A'
and bit 16-23 of lParam contains scancode
{
msg->wParam ='S' // It works fine.
msg->lParam +=xx01xxxx; // It doesnot work
}
so my doubt is here I have modified character 'A' to character 'S' by
using wParam.
Afterthat I tried to modify it using lParam so simply I have
incremented it by 1, (since '1F' is scancode of S).. but its not
working..
