duplicate block references
duplicate block references
hi there,
i am having a problem on getting block references. hopefully someone can help me with this.
i have a xref in my master drawing. in the xref, there is a block reference (inserted block). i wrote some code to get the block reference. i am expecting to get one block reference because there is only one. however, the code gives me duplicate block references. i don't know anything wrong in my code.
here is my code:
oddbblocktablerecordptr pblock;
oddbobjectid blockid;
// get the blockid for the xref
oddbblocktableptr pblocks = pdb->getblocktableid().safeopenobject();
oddbsymboltableiteratorptr pblkiter = pblocks->newiterator();
for (pblkiter->start(); ! pblkiter->done(); pblkiter->step())
{
// open the block
pblock = pblkiter->getrecordid().safeopenobject(oddb::kforread);
if (pblock->isfromexternalreference())
{
//the xref blockid
blockid = pblkiter->getrecordid();
}
}
//search in the xref for the reference of the given block(myblock|ref)
int found;
oddbblocktablerecordptr pms = blockid.safeopenobject();
oddbobjectiteratorptr pentiter = pms->newiterator();
for(pentiter->start(); !pentiter->done(); pentiter->step())
{
oddbentityptr pent = pentiter->entity(oddb::kforread);
oddbblockreferenceptr pref = oddbblockreference::cast(pent);
if (!pref.isnull())
{
oddbblocktablerecordptr pblock = pref->blocktablerecord().safeopenobject();
if (_stricmp(pblock->getname(), "myblock|ref") == 0)
{
found++;
}
}
}
thanks!

hi there,
i found what causes the problem. i put oddbxrefman::reloadall somewhere in my code. it somehow causes the problem.

hi al,
xref loading is redesigned in dd 1.12 (upcoming release). so probably the problem will disappear. but i can't say if the code is correct or not.
why don't you use oddbblocktablerecord::getblockreferenceids() ?..
