You can also try HBufC to hold your strings and take benefit of the ReAlloc() method.

Hi,

All APIs in Symbian use descriptors for all sorts of binary and textual data, so you should use these too. See for example the class RFile - its methods take TDes8 arguments for reading and writing, hence you can use e.g. TBuf8<> in your code to store the data.

I really recommend one of the Symbian books - you will get an in-depth view of the reasoning behind the unfamiliar patterns.

Cheers,
Pawel

Yeah I'm very aware of _L and _LIT (although I heard from several people that _L is frowned upon by symbian nowadays cos of the memory implications)

The point is these macros create literals encoded in your program, so unless you know what these are and how big they're gonna be at build they're useless...

If you obtain input during your codes run time - surely a literal makes no sense this context. So how *do you* handle text input or strings from files during run time?

Consider what the "char* flexibility" has done for the UNIX and Windows platforms stability and security .

We fortunately have some Macros ("_L()" and "_LIT()") you should really take a look at
