[DUG] Need help in format function

[Jolyon Smith]

Writing code that is thread-safe is still safe when there is only one
thread, but it sure does make things easier if/when you want to introduce
threads later on.  The only time that it makes sense to write code that is
knowingly not thread-safe is when you've made the conscious choice to write
single threaded code, but if the code is single threaded only because
threading has not even been considered (yet) .

 

The original poster may also have been simply unaware of the threading
issues with these functions.  Making assumptions is *always* dangerous.

I don't remember reading in the original post that Vikas needed the function
in a multi-threaded app?
In fact, the original FloatToStrF that Vikas used in his original post is
the non-threaded version, so I think it is reasonable to assume that he was
using it in a single threaded fashion. But thanks for pointing out how
useless Format ( Const Formatting  : string; Const Data  : array of const) :
string; is for multi-threaded situations.

Regards,
Colin

Atleast use the thread safe version

function Format ( Const Formatting  : string; Const Data  : array of
const; FormatSettings  : TFormatSettings ) : string;

Hey Phil :)

You beat me too it!

It's clean, readable and concise.
Plus there's no mucking around with strings!!

+1 from me :)

cheers, Colin
