I get the following error when I try to open a table.

"Cannot perform this operation when the engine is active"

in my application.

Delphi2006Pro with all updates and hotfix.
DBISAM 4.25 Build 3.

I checked older EXE files made with Delphi 7 with the same database
files and same source and everything works fine.

What could be the reason for this message?

Hi Karlheinz

Do you have any procedures attached to events on the dataset you're trying
to open? (ie, onBeforeOpen events, that could possibly be calling code to
modify settings to the engine component?

Cheers

Adam.

Karlheinz,

You must be trying to modify a property of the TDBISAMEngine component after
it has been activated.  Check for any references to the TDBISAMEngine
component in your code.
