exception on certain dwgs in sinlgedoc sample code
exception on certain dwgs in sinlgedoc sample code
i'm am getting a 0xc0000005 access violation in the singledoc sample code with certain dwg files. seems to be related to when the view is a perspective projection.
this same thing is happening in my application but found it to be reproducable with singledoc code (unmodifed) in dwgdirect1.13. i've attached a sample dwg to re-produce the problem.
here is the call stack when this exception occurs.

this is a bug of 1.13. thank you for a very explicit bugreport. next update of 1.13 and dd 1.14 will contais fix for this bug.
you can go round this bug by not setting to true viewport border visibility. if you comment out this line:
code:
pview->setviewportbordervisibility(true);
(singledocview.cpp), this bug won't appear.
sincerely yours,
george udov
