      Stream)

Use the CalculateCRC32ForStream method to calculate the CRC32 checksum value for any stream. This is useful for detecting changes to a given stream when used with the SaveStoreFileToStream and SaveStreamToStoreFile methods for loading and then saving a store file to and from a stream. For more information, please see the Stores topic in the ElevateDB SQL Manual.
