Topic: The notification about attempt of opening newer dwg format than it can be opened

[Andrey Bushman]

Hi all,

How can I get the notification about attempt of opening newer dwg format than it can be opened in current AutoCAD?

I've searched the similar events in the DocumentCollection Events and Database Events of the ObjectARX SDK documentation but I found nothing...

Thank you.

"but how do I check a DWG's version before I read it in?" Luckily, the first 6 bytes of any DWG indicate its version number

I have no problem with defining of DWG version. My question is about other theme.

I see.
I was thinking you'd have to test the file before attempting to open it.

I was thinking you'd have to test the file before attempting to open it.

User can try to open DWG version newer than AutoCAD can open through Windows Explorer or OpenFile dialog. I want to be notified about it through an event.

Perhaps using a command reactor and checking for a 'command failed' event will work. In Lisp (I don't use the .NET API) this works in principle.
