AcDb code with ObjectDBX?

[Pierrick Ingels]

Hi,

I'm trying to do a custom class derive from AcDbEntity with ObjectDBX and I
want to have an AcDbPolyline in this new class. But I get some problem when
I do that : the programm crash and telling me "User breakpoint called from
code at 0x77f86148" when I make some operation on the AcDbPolyline object.

So I have read the ObjectARX Developer's guide which say that when using
AcDb code with ObjectDBX, we must instantiate an AcDbDatabase object.

When I do that, the programm doesn't crash any more but my custom entity is
not displaying in my drawing.

Does someone knows how I can manage this problem?

Thanks in advance,

Pierrick Ingels
