Key mapping question. (for mobile phones with PC-like keyboard)

Question

For phones with mini keyboard (one button per one character, like a PC keyboard).
I'm trying to implement a form with few text boxes. The goal is to let user type the message like they're using a PC keyboard (unlike in traditional phones, where you need to press the 'numpad two' button three times in order to type the character 'C')
I've successfully implemented this functionality. But it's an ugly implementation because I use a switch-cases for each and EVERY keycodes.
Forexample:
char inputChar;
switch(keyCode)
case 97: input = 'A' break;
case 98: input = 'B' break;
// go on until every keys are covered, including the lower case letters. T_T
buffer.append(inputChar);
Yes I know that my programming skill is real crap >_<, so I try google for some good implementation method. But I always found only the detail about the traditional numpad implementations.
Ok, my real question is, can this keyboard implementation be done in a better way? The code should be able to look more beautiful than this, right?
Thank you. =)

Answer 1

I still don't get the problem here?
A textbox in a form will work just fine with those mini keyboards. You don't need to do anything for it..
Otherwise, this code can obviously be done better, a simple array where you just lookup your keycode will be much simpler and faster for instance.
