Autocad2004 and CDaoDatabase!!

Anonymous — Thu, 22 May 2003 06:04:36 GMT

Hello,
Iam converting our 2002 arx application to 2004.

I use the following code to connect to a CDaoDatabase-
AfxGetModuleState()->m_dwVersion = 0x0601;

pDatabase->Open(PATH,false,false,_T(""));

Whenever I close Autocad2004, I get an Unhandled Access Exception.
I dont get the error in 2002.

Thanks a lot.
jay

AFAIK, Microsoft is no longer supporting DAO in VC++ 7.0

I have given up and are now moving all DAO code into ADO.

We are trying to do the same.
We are just trying to roll out a quick version of current 2002 product.
Then create a Sql/access version of it.

I think there needs to some kind of setting for me to set to, not get that
exception.

Thanks.

Hi Jay,
I've got the same problem.
Have you found a solution so far?
Thanks, Petra

Hi pfluegge,

I got it to work.

There is a article on CDaoDatabase in ADN
which would help you with this.

As far I see it, you need to delete the daopointer,
try puttin this code in your unload module of your arx app.

AfxDaoTerm(); // Un-initialize DAO here...

_AFX_DAO_STATE*& pDaoState = AfxGetModuleState()->m_pDaoState;

delete (CNoTrackObject*)pDaoState; //destructor virtual

pDaoState = NULL;
