problem writing dwg 2000, 2004 files
problem writing dwg 2000, 2004 files
i'm using dwgdirect 1.9 libs for borland c++ builder on windows(32bit).
when i try to write the database to dxf or dwg,r14, things work fine, but
when i try to write to dwg,2000 or 2004, after a few k of the file is written, i get an exception:
oderror: "was open for write"

writes ok:

also typ of dxf works okay.
this doesn't happen for every case, and i don't have an odwriteex test case that makes this happen (i'll keep trying), so i'm hoping this info might be enough to narrow it down.
i wouldn't be surprised if its borland specific - i'd love to have the debug libs used to track down and fix
"was open for write" exception during writing a file means that some object was modified and not closed by the moment writefile() is called.
probably you have a smart pointer in your code pointing to some database object and as a result the object was not closed.
maybe r14 works because the object is not written to this file version.

thanks! i did have a pointer to a blocktablerecord that was still around.
zeroing it fixed the problem. strange that dxf and dwg r14 didn't complain..
