 |

ClientDataSet is named cdsCUSTOMER in code when I try to open it with:
cdsCUSTOMER.Active:=true;
gives message "Operation not supported".
In D7 design environment there is no problems if I check Active to true.
I use Interbase database and have following connection:
SQLConnection->SQLDataset->Datasetprovider->ClientDataSet->DataSource

The problem is bug in dbExpress, not allowing Delphi6 and Delphi7 be
installed on same machine, when dbExpress is used. I uninstalled D7 and
D6 and reinstalled D7, now there is this problem no more :)
Is there some more bugs to know about dbExpress? so far I have used IBX
and moving to dbExpress, to keep projects compatible to both FB and IB,
as there are separate drivers available.

At least in this case, I think it's not a bug in DBExpress. The problem was
a conflict version, since there were two dbexpint.dll installed in your
computer and your Delphi 7 app was seeing the Delphi 6 version of this
component (because the C:PROGRAM FILESBORLANDDELPHI6BIN was in the PATH
before the DELPHI7BIN). I had the 2 tools installed in my computer and had
to be very careful about the directories.
