PX_Double

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

BOOL PX_Double( 
   CPropExchange* pPX, 
   LPCTSTR pszPropName, 
   double& doubleValue  
); 
BOOL PX_Double( 
   CPropExchange* pPX, 
   LPCTSTR pszPropName, 
   double& doubleValue, 
   double doubleDefault  
);
pPX

Pointer to the CPropExchange object (typically passed as a parameter to DoPropExchange).

pszPropName

The name of the property being exchanged.

doubleValue

Reference to the variable where the property is stored (typically a member variable of your class).

doubleDefault

Default value for the property.

Nonzero if the exchange was successful; 0 if unsuccessful.

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