EOleSysError

Post by colucci » Thu 17 Jan 2008 22:53

Hey guys

I'm using the last sdac version and I'm getting an error message when I try to delete a record. Actually I have a master/detail relashionship with LocalMasterDetail option set to true and CachedUdpdate as well and a cascade delete on my sql server table. When a try to delete the master record, I get the follow message:

Project Project.exe raised exception class EOleSysError with message 'Seqüência de classe inválida'.

"Seqüência de classe inválida" is portuguese and it means something like "wrong class sequence". What can I do? It's driving me crazy ....

I could not reproduce the problem.
Please send me a complete small sample at sdac*crlab*com to demonstrate it, including script to create and fill table.

Also supply me the following information:
- exact version of SDAC. You can see it in the About sheet of TMSConnection Editor;
- exact version of your IDE;
- exact version of SQL server and client. You can see it in the Info sheet of TMSConnection Editor.

There's no more need .. I just found out what was wrong. I had a field on sql server as Tguid but on dataset fields the field was string.
Sorry for the inconvenience ...
