D4 and BDE3?

Our users use Paradox 5, Paradox 7, and Custom DB (BDE) apps. As a
result, we have several versions of the BDE on our network. Is it
possible to create apps using D4 and BDE3 instead of BDE5?

Right now some users receive an "Interface Mismatch. Engine Version
Different Error."

If not has anyone successfully overwritten BDE3 with BDE5?

No. This is just not possible. The BDE is backward-compatible, but not
forward compatible. That is, older versions of Delphi may use a newer
version of the BDE, but newer versions of Delphi cannot use older versions
of the BDE.

You must use BDE 5 with D4. Installing BDE 5 over BDE 3 will not cause any
problem and your other apps will work fine with BDE 5 (at least I have not
had any problem).

Steve:

I must disagree, this is possible ...

I have just had to re-compile a Delphi4 (BDE5) application in Delphi3 (BDE4.5)
to get it to run in a BDE 4.X environment.

Error: Interface Mismatch. Engine Version Different Error.
