PX_ULong

  • Článek

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

BOOL PX_ULong(
   CPropExchange* pPX,
   LPCTSTR pszPropName,
   ULONG& ulValue 
);
BOOL PX_ULong(
   CPropExchange* pPX,
   LPCTSTR pszPropName,
   ULONG& ulValue,
   long ulDefault 
);

Parameters

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

  • pszPropName
    Name of the property being exchanged.

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

  • ulDefault
    Default value for the property.

Return Value

Nonzero if the exchange was successful; 0 if unsuccessful.

Remarks

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