Sorry got carried away last night. The above messes lots of other things up. I'll look at this again and see if I can come up with something else.

If you have a Master->Detail relationship using the Datasource property, when the master Dataset is put into Edit mode the detail dataset looses it's place. I've had a look at the source and hopefully the attached fixes this problem. See the TZAbstractRODataset.RefreshParams procedure. Regards, Ben

Attached is (hopefully) a fix based on 6.1.5 code. See the GetTypeNameByOid function. I've made some small changes so that Domain types are recognised.

Regards,

I've been looking through the code and it seems that I can get my head round it. I'll look at creating a patch for this in the next couple of days (When I get the time).

I have an application which uses Postgresql 8.0.3 as the backend. I have been using ZeosDbo 6.1.5 but thought I'd try install '6.5.1 alpha CVS as of 13/10/2005' version of ZeosLib. Now when I try to connect one of the datasets I get 'Type mismatch for field 'location', expecting: String actual: Unkn...

Were you using one ZConnection component between more than one thread? I don't think that would be safe. I've used zeos within a threaded application now for some time but always used a seperate ZConnection for each thread. Or you could use a single, or pool of connections and seralize the database ...

Don't see the option! What version of Zeos are you using?

Does the following fix the problem? procedure TForm1.Timer1Timer(Sender: TObject); begin [b]Timer1.Enabled := False;[/b] try try if not ZConnection1.Connected then ZConnection1.Connect; ZQuery1.SQL.text := edit1.text; ZQuery1.Open; ZQuery1.first; if ZQuery1.Eof then caption := 'empty' else caption :...

Putting DBLogDlg in the Uses clause of the unit with the TZConnection component seems to work here.

I've just tried your app using Delphi 7 with ZeosLib 6.1.5 (and all the patches) and using FastMM4, and haven't found any problems. Have you applied the patches on the Sourceforge site? I think you may have a problem with your installation. I did use Zeos 6.1.5 with Delphi 4 and didn't have any prob...

I think DateUtils.dcu is a new unit in Delphi 6. Having this dependency limits Zeos to versions newer than this for no good reason that I can see.

One of the developers should have a look at this.

Would it be worth putting a news item or something on the Sourceforge site regarding this forum. The last thing on there about zeos is a news item dated 24 March 2005 saying the previous homepage is dead. This IMHO is not a very good advertisement. I am a long-time user of Zeoslib since the 5.x days...

IIRC the use of POSTGRESQL_STRICT_DLL_LOADING was to stop people using the default libpq.dll which is installed by other programs. This was the cause of many errors in Zeos. I think you would be better off selecting the postgresql-7.4 protocol and sticking with the libpq74.dll supplied with zeos. Th...
