explodetoblock causes exception
explodetoblock causes exception
i am currently using explodetoblock() with the attached file to explode all the blocks. it seems it will explode two blocks, but the third or forth block it tries to explode, would cause an exception and try{} would catch the error. i am currently using dwgdirect v1.11.01. does anybody know why this is the case? i was using v1.09 before and it seems to work fine then.
thanks

i can't reproduce the situation. what exception do you get? which blockreference is being exploded? what compiler do you use?

i don't know the exception. i am using vc2002. the code is the following:
oddbobjectid msid = pdb->getmodelspaceid();
oddbblocktablerecordptr pms = pdb->getmodelspaceid().safeopenobject(oddb::kforwrite) ;
oddbobjectiteratorptr pmsents = pms->newiterator();
oddbobjectidarray idstoexplode;
while (!pmsents->done())
{
oddbobjectid entid = pmsents->objectid();
oddbentityptr pmsent = oddbentity::cast(entid.openobject(oddb::kforwrite) );
if (pmsent->iskindof(oddbblockreference::desc()))
{
oddbblockreferenceptr pblock = pmsent;
if (pmsent->explodetoblock(pms) == eok) {
idstoexplode.push_back(entid);
}
}
pmsents->step();
}
this was an example that neil gave me back when dwgdirect just came out.

i managed to get the error and it says 'scalar deleting destructor'(unsigned int). the error code is 38
i hope this helps
thanks

i reproduced the problem with you code. (exploding them one by one in odamfcapp works). we'll try to fix it.

as a workaround you can use the next code:
code:
pdb->starttransaction();
...
<your exploding code>
...
pdb->endtransaction();
