Awww, it's not hate, you just need to be careful about how the code is 
laid out and what features you use. You'll need to fix this patch in a 
few places so here are some comments:

It's usually a good idea to submit the backend *first* and then the 
frontend, or better .. have them done all at once. Patches are supposed 
to be standalone, not stuff that'll only start working later (in the 
general case). For now I'd combine the two patches.

Try and keep alignment consistent, otherwise there's just extra visual 
noise for no good reason!

I'm afraid that unless my mail client is playing up that type of code 
isn't acceptable. You need to use indenting! Also please try and space 
stuff out, eg rather than:  if(tmpLen > 0)EnableWindow use if (tmpLen > 
0) EnableWindow(....);

No C++/C99 style comments unfortunately. Also please don't submit 
patches that have code commented out for no obvious reason.

Indenting is good, but indenting consistently is even better!

I think you may be mixing tabs and spaces or something here. Also making 
return look like a function is rather non-standard for C, use it as a 
statement: return TRUE;

If you're going to fall through please put a comment like /* fall 
through */ otherwise it looks an awful lot like a mistake.
