Has anyone added multi-currency support to an existing C++ application. I'm looking for any class libraries or function libraries to aid me in adding multi-currency support to a legacy VC++ application that also uses the currency type in associated ATL COM modules. I've already identified Rogue Wave's "SourcePro Analysis: Currency Module", but I would like to check out other options. Professional software, shareware, or freeware solutions are acceptable. Also any suggestions or comments on the Variant currency type.
