Re: Delphi 2005 & ZEOS Lib

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? :-).
