dwgdirect rendering crash
hi,
i'm having problem in rendering.
when i call update function of wingdi.gs device i get a crash.
i think i'm missing something in device initialization.
here is my code:
code:
// --------------------------------------------------------------
// initdwglayer
// --------------------------------------------------------------
void
cdwglayer::initdwglayer()
{
mtypeid = layer_type_dwg;
// odrxobjectimpl<exsystemservices> msysserv;
odinitialize(&msysserv); // dwgdirect initialization
// odrxobjectimpl<exhostappservices> mhostappserv;
mdbptr = mhostappserv.createdatabase( true, oddb::kmetric );
#ifndef _toolkit_in_dll_
odrx_init_static_module_map();
#endif
initrenderdevice();
}
// --------------------------------------------------------------
// initializerenddevice
// --------------------------------------------------------------
void
cdwglayer::initrenderdevice()
{
cview* pview = ::getmasterlayer()->getview();
crect rc;
getclientrect(pview->getsafehwnd(),&rc);
odgsmoduleptr pgs = ::odrxdynamiclinker()->loadmodule("wingdi.gs", true);

if( pgs.isnull() )
return;
mdeviceptr = pgs->createdevice(); // odgsdeviceptr mdeviceptr;
if( mdeviceptr.isnull() )
return;
odrxdictionaryptr pproperties = mdeviceptr->properties();
pproperties->putat("windowhwnd", odrxvariantvalue( (long)(pview->getsafehwnd()) )); /**/
if(pproperties->has("doublebufferenabled")) // check if property is supported
pproperties->putat( "doublebufferenabled", odrxvariantvalue( true ) );

if(pproperties->has("windowhdc")) // check if property is supported
pproperties->putat("windowhdc", odrxvariantvalue( (long)(pview->getdc()) )); // hwindowdc necessary for bitmap device
if(pproperties->has("doublebufferenabled")) // check if property is supported
pproperties->putat( "doublebufferenabled", odrxvariantvalue( true ) );
odgsdcrect gsrect(rc.left, rc.right, rc.bottom, rc.top);
mdeviceptr->setbackgroundcolor( rgb(255,255,255) );
//mdeviceptr->setlogicalpalette(theapp.curpalette(), 256);
if( !mdbptr->database() ) // oddbdatabaseptr mdbptr;
return;
int n = mdeviceptr->numviews();
// odrxobjectimpl<odgicontextfordbdatabase> mgicontext;
mgicontext.setdatabase( mdbptr ); // contect <-> database association
// odgsdeviceptr mdeviceptr;
mdeviceptr = oddbgsmanager::setupactivelayoutviews( mdeviceptr, &mgicontext ); /**/

//mgicontext.setviewportborderproperties( mdeviceptr, true );
#ifdef automatically_zoom_toextents_when_openingdrawing
if(zoomextents)
viewzoomextents();
#endif
mgicontext.enablegsmodel(true); // caching enable
n = mdeviceptr->numviews();

mdeviceptr->onsize( gsrect );

draw();
}
what is wrong in it?
thank you

this is the error:
unhandled exception at 0x0064dc99 in geoapp.exe: 0xc0000005: access violation reading location 0x00000000.
i noticed that the error is at the command:
geoapp.exe!oddbobjectid:penobject() + 0x41
maybe my database is not correctly cofigured?
