Re: [Quickfix-developers] Using UNICODE with the QuickFix C++ Library

[<OM...@th...>]

Constantin,

As far as CPU time, I'm not sure such a thing would help you.  FIX is an
ASCII standard for the most part.  The exception being the Encoded fields
which can be transmitted with different character sets.  At one point or
another, these strings would need to be converted before being sent across
the wire.

If you still want QuickFIX to accept wstrings for ease of use, you should
be able to do the following.

In FieldTypes.h, change all the "typedef std::string <SOMETHING>" lines to
read, "typedef std::wstring <SOMETHING>"

In FieldConvertors.h, replace the line "typedef EmptyConvertor
StringConvertor" with a class that will convert between strings and
wstrings (see the other convertors in the file for how to do this)

Finally, in Field.h, change all references in the StringField class from
std::string to std::wstring.  Use your new convertor where appropriate (see
other field types for examples).

I think that is all the steps.

Alternatively, I usually like to have a small inline method I can use to
conveniently do such conversions in a manner such as this:

ClOrdID clOrdID(w2a(L"MY STRING"));

--oren

Hi,

I integrated QuickFix C++ as apart of a COM+ object
in the context of Windows 2000; all the rest of data
in my application is BSTR and UNICODE.
I spend a lot of (CPU)time and lines of code converting between
std::string and WCHAR; I saw that the .NET library
implementation uses wstring, any idea to have the
same with the C++ Windows library ?

Regards,
Constantin

PS I also need some encryption(and even compression for some very big
XmlData diels),
does anyone have a hack to support opaque data type ?
