| What about Delphi 2007? Old driver works on Delphi 2006, but don't cooperate with Delphi 2007. We receive stupid message that DLL can't be found. Are you going to prepare new DLL or is it possible in some way to use old driver on 2007. |

Sorry, but we don't support D2007, because Borland don't provide documentation.

It appears Peter Sawatzki has the necessary documentation, as he has released a version of his AS400 dbexpress driver (dbexpca400) that works with Delphi 2007!
Refer http://www.sawatzki.de
Version: 3.0.07
Date: 16.8.2007
rewrote driver for Delphi 2007
It appears you have an opportunity here. I have just upgraded to Delphi 2007, but I am unable to use it as there is a serious memory leak in the dbxase30.dll Sybase ASE dbexpress supplied by CodeGear with the enterprise version of Delphi 2007 / RAD Studio 2007.
The memory leak occurs whenever you ExecSQL using a TSQLQuery component, and currently renders Delphi 2007 unusable for Sybase ASE dbexpress development.
I have reported this issue with example code to recreate to CodeGear Quality Central, but as you remains unresolved.
It would be great if Visoco could release an updated driver for ASE 12.5 for Delphi 2007 that actually works without memory leaks.
Alternatvely, if anyone has managed to get the CodeGear ASE dbxase30.dll driver DLL to work without memory leak issues, I would really like to hear how they are doing this.
In the meantime I am stuck with Delphi 7.1 for ASE dbexpress development using the Visoco driver. However, unfortunately Visoco's existing driver also has multi-processor concurrent multi-threading issues, requiring all dbexpress calls that involve database connectivity to be serialised via semaphores. This drastically reduces performance and adds coding complexity etc.
Any feedback appreciated!
