    bool result = false;
    //if the parameter is readonly, you can�t change the value of it
    if (null != parameter && !parameter.IsReadOnly)
    {
        StorageType parameterType = parameter.StorageType;
        if (StorageType.Double != parameterType)
        {
            throw new Exception("The storagetypes of value and parameter are different!");
        }
        //If successful, the result is true
        result = parameter.Set(value);
    }

    return result;
}
