PX_Float

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

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

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

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.

Remarks

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