Re: [Lazarus] Editing a TDBf record
That's great, thank you Luiz: works a treat!
TDbf is such a nice lightweight solution for incorporating database
functionality into monolithic applications and it's still relevant
even though it appears that development stopped years ago.

[Lazarus] Editing a TDBf record
Does anyone have experience of TDbf?
I want to change an existing record:
ival:=strtoint(ConFigs.Values['hubID']);
Dbf1.Open;
while not(Dbf1.EOF)do
begin
if Dbf1.FieldByName('hubID').AsInteger=ival then
begin
Dbf1.FieldByName('Loc').AsString:=Configs.Values['Location'];
Dbf1.FieldByName('EstName').AsString:=Configs.Values['Establishment'];
Dbf1.FieldByName('NetwkName').AsString:=NetwkName;
Dbf1.FieldByName('VATNo').AsString:=Configs.Values['VATNumber'];
Dbf1.FieldByName('TelNo').AsString:=Configs.Values['TelNumber'];
Dbf1.FieldByName('User').AsString:=username;
Dbf1.Post;
end;
Dbf1.Next;
end;
Obviously ival has the value of the 'hubID' field of the record that I
want to update and I'd like to replace all the fields in the record
with new values.
However, I'm getting an error which says: "Project raised exception
class 'Unknown' "

What's that animal? It's not a cheetah or a cat. I think it could be some kind of feline baby, perhaps a baby lynx.

Check it's been exported, i.e. processes forked by the shell simply
might not be getting a copy.

Thanks Sergei, I'll investigate. I've also come across a toolset called
usbio which is expensive but available for a limited-time evaluation
(four hours per session) and apparently includes Delphi support. I'm not
expecting to get very far, but I'm interested to see just how much
functionality the Edgeport stuff grafts onto NT4.

No, my project wasn't to create mozilla plugins. It was to enabled mozilla plugins to run outside mozilla, but in a Delphi/Lazarus program. We needed to have a cross-platform Flash component running inside our applications. Like an embedded ActiveX flash component in Delphi - for for Linux and Windows platforms. This is what I created, but I was pulled off the project, because we decided to implement a CGI application instead and simply use a web browser to run that section of our program. http://opensoft.homeip.net/wiki/wiki.cgi?p=mozilla-plugin-panel I haven't completed the project, but the last time (some three years back) I managed to get Flash and Acrobat browser plugin embedded in a Lazarus application. Linux support was not working yet. Source code is available on SourceForge. Hopefully some day I'll have the time to complete that project. It has the potential to run any mozilla plugin inside a GUI application, which will be very cool. :-) Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
