Thanks, I'll try again later.

Whenever I open and run a delphi project with zConnection, I always get an error: "Error reading ZConnection1.PreprepareSQL: Property PrepepareSQL does not exist" I can set the property to TRUE so my delphi project runs normal, but every time I close out and re-open, the property resets to...

To fix abstract error in TZConnectionGroup librarylocation property, download my attachment file.

version : ZEOSDBO-7.0.3-stable

I will check the svn branch that you mention.

Thanks.

Sorry, I meant TZGroupedconnection. It works now, I change all TZConnection to TZAbstractConnection in ZPropertyeditor.pas Components that compatible with TZGroupedConnection so far: - TZReadOnlyQuery - TZQuery - TZTable - TZStoredProc - TZSQLMetadata I tested it under Windows 7, Delphi 2007, Firebi...

Ok, I still need time to make TZSQLMetadata compatible with TZConnectionGroup, I will upload the diff report and the new files after that.

Btw, what software you're using to make a diff report ?

I make several modifications and add 2 new components in ZEOSDBO-7.0.0-alpha (Delphi 2007 package only): Feature: - New TZAbstractConnection - New TZConnectionGroup - New TZGroupedConnection - Simple encrypt/decrypt for User/Password in TZConnectionGroup There's a demo on how to use TZGroupedConnect...

I've got a new problem, ZTable, ZQuery and ZReadOnlyQuery can't use TZGroupedConnection as their connection because TZGroupedConnection parent class now is TZAbstractConnection and not TZConnection. I can re-create TZconnection base on TZAbstractConnection class, but now I have to remove all ZConnec...

Ok, I'll do it.
Of course, I still need a lot of help from you and Zeos community.
I'll post the component source in here later.

I'm glad if Zeos wants to add TZConnectionGroup and TZGroupedConnection to Zeoslib 7. And thanks for the offer, but I don't think I'm quite capable to do this job. Hiding published properties in TZGroupedConnection base class (TZConnection) is still impossible for me. Maybe someone who have more exp...

Thanks Luzcka and Mark, I want to make ZTransaction works for every Zeos version, so using ZConnection as ZTransaction base class is the simple way to do that, and the reason why I choose 'ZDbConnection' name, not 'ZDatabase', because I'm worried that someday my component name (assuming I use ZDatab...

I use ZDbConnection to store User, Password, Database, Port and Protocol. Every Ztransaction which connected to ZDbConnection in design or run time, didn't have to provide with the same User,Password or Database again. In my project design, I use 1 ZDbConnection in Data Module, and ZTransaction in o...

Another fix for my component: unit ZTransaction; interface {$I ZComponent.inc} uses Types, SysUtils, Classes, ZDbcIntfs, DB, ZDbcAdoUtils,Forms, ZCompatibility, ZConnection, ZSequence, Dialogs, ZDbConnection; type TZTransaction = class(TZConnection) protected FZDbConnection: TZDbConnection; FZDbConn...

I see... , thanks for the answer. I tried to create my own components based on TZConnection class, and this is my working component so far: TZDbConnection and TZTransaction. unit ZTransaction; interface {$I ZComponent.inc} uses Types, SysUtils, Classes, ZDbcIntfs, DB, ZDbcAdoUtils,Forms, ZCompatibil...

Do ZEOS have a component like TDatabase (for BDE) or TIBDatabase (for IBExpress)? so I don't have to set the protocol, username and password for every ZConnection in my form ?

Thanks..!
