singledoc : access violation
hello
i can't read any dwg file after reading dwg file with paper space.
void csingledocview::resetdevice(bool zoomextents)
{
:
m_pdevice = pgs->createdevice(); //occur 0xc0000005 access violation
:
}
dwgdirect version 2.06.01
attached files
that is - you opened the first file with singledoc example, and then, opening the second you've got an exception?

i was able to reproduce the crash.
you may use teh following fix: replace csingledocdoc::onopendocument with the following code
code:
bool csingledocdoc::onopendocument(lpctstr lpszpathname)
{
if (!cdocument::onopendocument(lpszpathname))
return false;
/**********************************************************************/
/* load the specified dwg file into the database, allow code page */
/* conversion disallow partial load. */
/**********************************************************************/
try
{
if (!m_pdb.isnull()) // clear gs model associated with the previous database
{
position pos = getfirstviewposition();
while (pos)
{
csingledocview* view = (csingledocview*)getnextview(pos);
view->m_pdevice = 0;
view->m_pprinterdevice = 0;
}
}
m_pdb = theapp.readfile(lpszpathname, true, false);
}
catch(oderror& /*e*/)
{
}
catch(userbreak)
{
return false;
}
return true;
}
