PX_ULong

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

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

Return Value

Nonzero if the exchange was successful; 0 if unsuccessful.

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.

Remarks

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