TryParsePropValue() public method

This method provides a the functionality to convert any object to the appropriate type for the particular BOProp Type. e.g it will convert a valid guid string to a valid Guid Object.
public TryParsePropValue ( object valueToParse, object &returnValue ) : bool
valueToParse object The value to be converted
returnValue object
return bool
