Which version BDE

[Roger Cigol 103]

I had a job to move away from a BDE / Paradox system to FireDAC MS Access a while back. I ran into a problem which I solved as discussed here - might (or might not) be useful:

Hmm... Wordpress is acting up and sending me to my own site when I try to follow the link.

Convert from Delphi 7 to whatever newer Delphi version you fancy and keep the BDE. That UNICODE string conversion is less problematic than many people (including me until recently) think. Only very few places need to be changed at all. Unless you were (ab)using strings for storing binary data, that might cause more work.

From my own experience, this could vary very widely, from just recompile to 1-2 months of rewriting and hunting subtle bugs. F.ex., I converted EhLib 2.x in about several hours but SimpleXML took about a week. All this depends on how clean and correct the code is written.

I use Paradox tables in my old application, and therefor I use the Database Desktop. But as @Virgo said, it shows the error, and the nothing more happens after I click run this program without getting help............

FireDAC doesn't support Paradox at all. You have to port to another Database, e.g. Firebird. But beware, no more SetRange and Filter, but SQL only.

I don't agree you can use ADO driver, even if I agree with your second remark

Not necessarily Firebird : Paradox = Mon User so SQLite is sufficient

FDTable have these functions, personally  I prefer FDQuery but ...

Expect.... That requires BDE for some Paradox features anyway. From what I recall Paradox version 7 tables were one of those things.
