iter (method seek) get error
hi,
how we find the linetypename from a spec. layer with seek-method ?
++++++++++++++++++++++++++++++
//iterate layertbl
...
//sep. c++block in func because equal variablename piter
{
oddblayertableptr plinetypes =
pdb->getlinetypetableid().safeopenobject();
oddbsymboltableiteratorptr piter = plinetypes->newiterator();
piter->seek(player->linetypeobjectid());
oddblayertablerecordptr plinetype =
piter->getrecordid().safeopenobject();
os << plinetype->getname() << ";";
}
....
++++++++++++++++++++++++++++++
we get follow message:
"unknown software exception" (0x80000003) at (0x01020ae23)
what is wrong ?
thanks fo help
ralph

hi,
probably you get exception because you are assigning linetype table pointer oddblayertableptr.
you need not use seek method you can open linetype table record directly having obtained its object id from layer.
oddblinetypetablerecordptr plinetype = player->linetypeobjectid().safeopenobject();
out << plinetype->getname();

++++++++++++++++++++++++++++
