Hello Jan, Thanks for your fast response but we think that there is a little misunderstanding about ZConnectionFbDB. The ZConnectionFbDB is not used in threads for connection but only for getting the parameters of connection (read-only and it does not change because it is read from ini file only on ...

Hello Jan, we are sorry to hear that you encountered these issues (we apologise but we didn't realise that REST/DataSnap is not part of other versions - we let it to be created by project wizard). With this post, we are adding new files in which there is a new example where DataSnap is exchanged for...

Hello. We would like to ask if anything changed in this matter and if you found posted demo helpful in solving this problem. Or are we doing something wrong in using ZeosLib components in our example and that's why it does not work and crashes into AV. Additionally: We have upgraded to latest ZeosLi...

Hello. After a longer time here we have prepared a promised example. 1. demo_example.7z is source code of the example in RAD XE 10.4.2 (note: demo_example\Win32\Debug is configuration file demo_example.ini , which should be placed by generated exe and in it should be configured database parameters a...

Hello. Thanks for your assistance and sorry for late response (because of some project testing). Your suggestion with using settings "FirebirdAPI=legacy" was very helpful and application now runs fine without these crashes. Additionally we would like to note that when crash (close all lob ...

Hello, that the strangest thing, because each pair of TZconnection and TZQuery are created on separated thread by calling new (that means that each SQL query has their own Zconnection and TZQuery) and crash happens after some time on TZQuery->Open() a and then on TZconnection->Disconnect() as noted ...

Hello, we would like to ask for some help because we ran into issue when we updated from Firebird 2.5.8 to 3.0.7. Note: we are using C++ (XE10.4.2) On first look application did work OK, but after few days it crashed with Exception "close all lob streams before closing the resultset". Cras...

Hello, I have a simple question. We use Firebird database, Zeos 8.0 and ZIBEventAlerter component. It seems to work quite well. Zeos v8.0 contains also ZEventListener component. Where and how (or for what) could be used this component? Thank you in advance for your answer. Best regards, Vaclav Korecek

Thank you for your fix regarding this.
We tested the latest update and it works quite well.

Once more thanks.

Best regards,

Hello, after some time we returned to this because we are now converting project from XE5 to XE10.4 C++ Builder. Here are some of our results for the issue: just assign all parameters and use the .AsXXX properties and never the .Value property. This doesn't work in either case because there seems to...

Hi, I re-created my app not to be depended on third party components to be as simple as possible. I have also cut most of data tables from database and cut most of data of the table. I also changed some data of the table. There is provided definition DB as well as the database backup. There is also ...

I am sorry for my late answer because of another project. To your question: Are you sure that creating a new parameter is required under C++ builder? Maybe we can try without clearing and recreating the params, only resetting their values? What you asked me for was used in original project with Zeos...

I know about possibility to use AsInteger but I have tried another solution. Shortly: Using of "AsInteger" does not help either. Now I tried following code: siSearch = 549; ZQuerPlaces->Params->CreateParam(ftInteger,"xZIPCODE",ptInput); ZQueryPlaces->Params->ParamByName("xZI...

A nice question. Thank you. I have to say to your question that the query works very well in IBExpert (SQL Editor) tool or in the Squirrel-SQL client. No problem. Zeos component works well but with wrong (different) parameters. However you made me to more investigate in differences of Zeos v7.2.4 vs...

Hi, I have a problem with ZeosLib and its parameters. I use Firebird 2.5 , Embarcadero C++ Builder XE6, XE10 and XE10.3 Rio. I can see difference between ZeosLib 7.2.4-stable and v8.0.0 Beta . Code I use in my application is same for both above named versions of Zeos. The query which I use is also s...
