Call this function within your control's DoPropExchange member function to serialize or initialize a property of type currency.
BOOL PX_Currency( CPropExchange* pPX, LPCTSTR pszPropName, CY& cyValue ); BOOL PX_Currency( CPropExchange* pPX, LPCTSTR pszPropName, CY& cyValue, CY cyDefault );
Pointer to the CPropExchange object (typically passed as a parameter to DoPropExchange).
The name of the property being exchanged.
Reference to the variable where the property is stored (typically a member variable of your class).
Default value for the property.
Nonzero if the exchange was successful; 0 if unsuccessful.
The property's value will be read from or written to the variable referenced by cyValue, as appropriate. If cyDefault is specified, it will be used as the property's default value. This value is used if, for any reason, the control's serialization process fails.
