memory leaks in "queryx" function or my error?
i use odamfcappdll with visual studio 6.
for to see the problem you can modify the funcion oneditacisconversion()
if (!pnewobj.isnull())
{
// test memory lek
if (((oddbentityptr )pnewobj)->iskindof(oddbpolyfacemesh::desc()))
{
oddbpolyfacemeshptr ppoly = ((oddbentityptr )pnewobj);
oddbobjectiteratorptr piter = ppoly->vertexiterator();
for (; !piter->done(); piter->step())
{
oddbpolyfacemeshvertexptr pvertex = piter->entity()->queryx(oddbpolyfacemeshvertex::desc());
}
}
// end test
pent->handoverto(pnewobj);
}
you can read the attach file called "region.dwg". when you exit from application several memory leak appear. it is a my error in use of queryx?
thank's for help.
attached files
how can i obtain vertex and face of polyfacemesh without use queryx?
try next code - in this case no memory leak
// test memory lek
if (((oddbentityptr )pnewobj)->iskindof(oddbpolyfacemesh::desc()))
{
oddbpolyfacemeshptr ppoly = ((oddbentityptr )pnewobj);
oddbobjectiteratorptr piter = ppoly->vertexiterator();
for (; !piter->done(); piter->step())
{
oddbentityptr pentity = piter->entity();
if (pent->iskindof(oddbpolyfacemeshvertex::desc()))
{
oddbpolyfacemeshvertexptr pvertex = piter->entity();
}
if (pent->iskindof(oddbfacerecord::desc()))
{
oddbfacerecordptr precord = piter->entity();
}
if (pent->iskindof(oddbsequenceend::desc()))
{
oddbsequenceendptr psqend = piter->entity();
}
}
}
// end test
great!your code work fine without memory leak. it is only change pent with pentity.
is it a good idea change code in class oddbpolyfacemesh_dumper in example odreadexdll and odreadex?
thanks a lot
