get vertices from an entity
get vertices from an entity
hi sergey
thanks for your answer. but my problem is i don't know how to cast or how to get an oddbline from oddbentityptr. if there is any idea please let me know it.
thanks a lot

oddbentityptr pent = .... ;
oddblineptr pline = oddbline::cast(pent);
if (pline.isnull()
{ // it was not oddbline or pent was null
}
else
{ // it is realy oddbline
odgepoint3d pstart = pline->startpoint();
...
}
if pobj is not null, you also can check object type like this:
if (pobj->iskindof(oddbline:: desc()))
{
// it's oddbline or its inheritor
}
or
oddbline * pline = (oddbline*)pobj->queryx(oddbline:: desc());
if (pline)
{
// it's oddbline or its inheritor
}

hi sergey

thanks in advance sergey.

hi,
to say what is the reason it's necessary to know what kind of crash, in what function etc.
maybe dwgdirect is not initialized, maybe database is created without default objects ...
btw, odamfcapp is a sample mfc application which reads/writes files and creates new database too.
try to look at it.
