Hi,

I have just looked at Ace Reporter. Yes, it can use an ZEOS connection to Delphi, but I wasn't very lucky, because after a few minutes, I got a stack overflow with Ace Reporter.... I think I'll use CR with ODBC, that's not too bad actually...

Zeos 6.1.x and 6.5.x are a built around libpq 7.4. The last major protocol revision in pg was 7.3 IIRC. The pg support of Zeos is pretty good, I personally worked on testing and fixes for the pg driver during for Zeos 6.0 and 6.1. The earlier versions had problems with arrays, not sure about the newer ones since I don't happen to be doing anything with Zeos at this particular moment.

In your other mail you asked about Crystal Reports. I've never actually used CR with Delphi, but I'm assuming it makes its own independent connection to the database. In this case, yes it will require the ODBC driver but you should not have too many problems...you are not using the BDE. If there is some sort of reliance on the BDE dataset objects (TDataset, TTable), then I'd suggest dumping CR and picking up Ace Reporter. You have looked at Ace Reporter, right? :-).
