Call this function within your control's DoPropExchange member function to serialize or initialize a property of type float.

BOOL PX_Float(
   CPropExchange* pPX,
   LPCTSTR pszPropName,
   float& floatValue 
);
BOOL PX_Float(
   CPropExchange* pPX,
   LPCTSTR pszPropName,
   float& floatValue,
   float floatDefault 
);

Параметры

pPX
Pointer to the CPropExchange object (typically passed as a parameter to DoPropExchange).
pszPropName
The name of the property being exchanged.
floatValue
Reference to the variable where the property is stored (typically a member variable of your class).
floatDefault
Default value for the property.

Возвращаемое значение

Nonzero if the exchange was successful; 0 if unsuccessful.

Заметки

The property's value is read from or written to the variable referenced by floatValue, as appropriate. If floatDefault 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.
