TopSpeed File compatibility with prior versions
Another small misunderstanding arose from a discussion that took place at the UKCUG. We received a few emails referring to a post on the Clarion Handy Tools website that stated, “The format of .TPS files will change in Clarion 7. The older format will be recognized and auto-converted by C7 after which the file is no longer accessible by previous Clarion versions.”
This isn’t true; all versions of Clarion, including both Clarion7 and Clarion.Net can read and write TopSpeed files created with any version of Clarion without any compatibility issues. So you can put your mind at ease.
But since we’re talking about compatibility with prior versions I should mention a single case which would introduce incompatibility. As previously announced the new version of the TopSpeed driver (available in Clarion 7 and Clarion.Net) introduces the ability to use any encryption algorithm supported by any of the encryption providers that plug into the Windows encryption subsystem.
For more details on the new encryption features see the post:
Enhanced Encryption Support in the TopSpeed driver
.
If a developer chooses to encrypt a TopSpeed file using for example, the AES encryption provider, then obviously prior versions of the driver which don't support the new encryption options will be unable to decrypt the data. But other then that single case, your Clarion 6 (or prior Clarion versions) and your Clarion 7 or Clarion.Net applications can happily coexist, with no problems reading and writing to common shared files.
