[求助]各位高手帮帮忙：(扩展字典问题)
[求助]各位高手帮帮忙：(扩展字典问题)
我想为各个层添加扩展字典，来记录层上的一些信息，下面是我的函数(我把层名作为字典的名字)
createdictionary()
{

acdbobjectid pcurlayerid;
pcurlayerid=acdbhostapplicationservices()->workingdatabase()->clayer();
acdblayertablerecord* ptrec;
acdbopenobject(ptrec,pcurlayerid,acdb::kforwrite);
ptrec->createextensiondictionary();
acdbobjectid dictobjid,xrecobjid;
acdbxrecord *pxrec = new acdbxrecord;
acdbdictionary* pdict;
dictobjid=ptrec->extensiondictionary();
ptrec->close();
acdbopenobject(pdict,dictobjid,acdb::kforwrite);
pdict->setat(pclname,pxrec,xrecobjid);
pdict->close();

resbuf* head;
head=acutbuildlist(acdb::kdxftext,name,acdb::kdxfreal,area,acdb::kdxfreal,
rlength,acdb::kdxfreal,rwidth,acdb::kdxfint16,num,rtnone);
pxrec->setfromrbchain(*head);
pxrec->close();
acutrelrb(head);
}//其中name、area、length、width、num分别为cstring double double double int型
为了验证扩展字典的正确性，我编写了下面的函数进行验证
readdictionary(cstring name)
{
acdblayertable *player;
acdblayertablerecord *prec;
acdbobjectid dictobjid;
acdbdictionary *pdict;
acdbxrecord *pxrec;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(player,acdb::kforread);
player->getat(name,prec,acdb::kforread);
player->close();
dictobjid=prec->extensiondictionary();
prec->close();
acdbopenobject(pdict,dictobjid,acdb::kforread);
pdict->getat(name,(acdbobject*&)pxrec,acdb::kforread);
pdict->close();
struct resbuf* prblist;
pxrec->rbchain(&prblist);
pxrec->close();
prblist->rbnext;//从第二个数据开始输出
acedprintf("area=%f\n",prblist->resval.rreal);
prblist->rbnext;
acedprintf("length=%f\n",prblist->resval.rreal);
prblist->rbnext;
acedprintf("width=%f\n",prblist->resval.rreal);
prblist->rbnext;
acedprintf("num=%f\n",prblist->resval.rint);
acutrelrb(prblist);
}
编译运行都没有问题，可就是得不到我输入的结果，请问各位高手，我的程序哪里有问题；还是不可以为层添加扩展词典
问题解决了，这是一个愚蠢而低级的错误出错的地方我已经做了标注，下面是改进后的代码，希望大家不要犯和我类似的错误
resbuf *prblist;
resbuf *ptemp;
pxrec->rbchain(&prblist);
ptemp=prblist;
pxrec->close();
ptemp=ptemp->rbnext;
acedprintf("area=%f\n",prblist->resval.rreal);
ptemp=ptemp->rbnext;
acedprintf("length=%f\n",prblist->resval.rreal);
ptemp=ptemp->rbnext;
acedprintf("width=%f\n",prblist->resval.rreal);
ptemp=ptemp->rbnext;
acedprintf("num=%f\n",prblist->resval.rint);
acutrelrb(prblist);
哈哈，我又回来了。互相学习，共同提高qq:250623330我的群：1083110
