You'd expect a currency class to be able to format a given currency for output, to read one in, to convert from one currency to another and to do calculations with the value.

i am using Visual Studio 2010 and working on OPOS development and using ActiveX control : OPOSScale.ocx
this ocx has a property like :
put_UnitPrice(CY newValue);
So which type of value i have to pass in the above parameter.

Waiting for your valuable feedback.........
