[arx]求助 块的制作出现问题
以下是我的程序：程序实现（1）makeablock制作一个块 块包含的实体自己选定（2）printall 显示刚才制作的块的一些特性
问题：为什么特性不能显示？
void ccfch1makeablock()
{
// todo: implement the command
acdbblocktablerecord *precord=new acdbblocktablerecord();
char blockname[10];
acedgetstring(null,"\n输入块的名字",blockname);
precord->setname(blockname);//"asdk-no-att"
acdbblocktable *ptable;
acdbobjectid recordid;
acdbhostapplicationservices()->workingdatabase()->getblocktable(ptable,acdb::kforwrite);
ptable->add(recordid,precord);
ptable->close();
ads_name entname,entn;
long len;
acdbobjectid pentid,pid;
acdbentity *pent;
acedssget(null,null,null,null,entname);
acedsslength(entname,&len);
for(int i=0;i<len;i++)
{
acedssname(entname,i,entn);
acdbgetobjectid(pentid,entn);
acdbopenacdbentity(pent,pentid,acdb::kforread);
precord->appendacdbentity(pid,pent);
pent->close();
}
precord->close();
acedssfree(entname);
acutprintf("\n块操作完成");
}

void ccfch1printall()
{
// todo: implement the command
int rc;
char blkname[50];
rc = acedgetstring(adesk::ktrue,
"enter block name <cr for current space>: ",
blkname);
if (rc != rtnorm)
return;
acutprintf("\n the 1");
if (blkname[0] == '\0') {
if (acdbhostapplicationservices()->workingdatabase()->tilemode()
== adesk::kfalse) {
struct resbuf rb;
acedgetvar("cvport", &rb);
if (rb.resval.rint == 1) {
strcpy(blkname, acdb_paper_space);
} else {
strcpy(blkname, acdb_model_space);
}
} else {
strcpy(blkname, acdb_model_space);
}
}
acutprintf("\n the 2");
acdbblocktable *pblocktable;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(pblocktable, acdb::kforread);
acdbblocktablerecord *pblocktablerecord;
pblocktable->getat(blkname, pblocktablerecord,
acdb::kforread);
pblocktable->close();
acdbblocktablerecorditerator *pblockiterator;
pblocktablerecord->newiterator(pblockiterator);
acutprintf("\n the 3");
for (pblockiterator->start(); !pblockiterator->done();
pblockiterator->step())
{
acdbentity *pentity;
pblockiterator->getentity(pentity, acdb::kforread);
acutprintf("\n the 4");
acdbhandle objhandle;
pentity->getacdbhandle(objhandle);
char handlestr[20];
objhandle.getintoasciibuffer(handlestr);
const char *pcname = pentity->isa()->name();
acutprintf("\n the 5");
acutprintf("object id %lx, handle %s, class %s.\n",
pentity->objectid(), handlestr, pcname);
pentity->close();
}
delete pblockiterator;
pblocktablerecord->close();
acutprintf("\n");
}
是不是应该把const char *pcname = pentity->isa()->name();的const去掉?
不是 因为 for (pblockiterator->start(); !pblockiterator->done(); pblockiterator->step())这个循环进不去，块浏览器根本没有发现实体
