API DATABASE_CONTROL EXAMPLE ERROR

SajW — Tue, 04 Oct 2022 14:51:53 GMT

I went through the post in the following link https://Archicad-talk.Graphisoft.com/viewtopic.php?f=23&t=62110 and changed the following lines of code to run the project.

before
DBASSERT (book->save (UNISTR_TO_LIBXLSTR(filepath)));
book->release ();

after
bool aaaa= book->save (UNISTR_TO_LIBXLSTR(filepath))
book->release();

But I keep getting the following errors in the GSException.hpp file. Can I know the problem?

Hello,

Could you please tell us, which version of the API Development Kit and Visual Studio are you using?

Thanks,
Dénes

Re: API DATABASE_CONTROL EXAMPLE ERROR

SajW — Fri, 07 Dec 2018 14:55:03 GMT

Hello,

Thanks for the reply.
API Development Kit 22.3004
Visual Studio 2017

Tibor Lorantfy — Sat, 15 Dec 2018 09:01:24 GMT

Hi SajW,

ARCHICAD 21 and 22 both use the Visual Studio 2015 compiler for building add-on projects.
You can use Visual Studio 2017 of course, but please make sure to set Visual Studio 2015 (v140) platform toolset (see attached image below).

For further informations please read our blog post about working in Visual Studio 2017: http://archicadapi.graphisoft.com/working-in-visual-studio-2017

Regards,
Tibor

SajW — Mon, 17 Dec 2018 01:35:17 GMT

I have followed the steps given in the blog post and the Platform Toolset is set to Visual Studio 2015(v140), but I keep on getting the same errors.

Re: API DATABASE_CONTROL EXAMPLE ERROR

SajW — Thu, 20 Dec 2018 07:18:37 GMT

It worked when I tried with Visual Studio 2015
