   hi
   i am trying to get into symbian c++ development. i have no background whatsoever with symbian.
   i am using carbide.c++ with a nokia n91 (s60 3rd edition).
   the hello world app compile and run perfectly, but when i use iEikonEnv->TitleFont();in my program i get an error: undefined identifier iEikonEnv. this happens wherever i have iEikonEnv, not only for TitleFont();
   i have this in my AppView class.
   can anyone please shed some light on this as i can not find a solution anywhere.
   thanx

   iEikonEnv is a bit tricky: it is not a variable, it is a macro defined in eikdef.h (it is casting the existing iCoeEnv to a CEikonEnv*). Make sure it is included (and you may also need to include eikenv.h).

   on which class you are calling verify that you have a member variable iEikonEnv

   Try this way rather

   Code:

   CCoeEnv::static()->AppUi()

   include apropriate headers and lib
