我怎么把一个选择集放到一个属性块的定义里去?我是这样做的，但不行！请帮帮我acutPrintf("It is begin!\n");
int retCode = 0;
AcDbBlockTable *pBlockTable = NULL;
AcDbBlockTableRecord *pBlockRecord=new AcDbBlockTableRecord;
AcDbObjectId entId,blockId;
ads_name ss;
AcDbEntity *pEnt;
ads_point pt1,pt2;
AcGePoint3d basepoint;
pBlockRecord->setName("BlockWithAttribute");
if(acedGetPoint(NULL,"Please input a point:\n",asDblArray(basepoint))!=RTNORM)
return;
pBlockRecord->setOrigin(basepoint);
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBlockTable,AcDb::kForWrite);
pBlockTable->add(blockId,pBlockRecord);
if(acedGetPoint(NULL,"请输入左上角:\n",pt1)!=RTNORM)
return;
if(acedGetPoint(NULL,"请输入右下角:\n",pt2)!=RTNORM)
return;
acedSSGet("C",pt1,pt2,NULL,ss);
acdbGetObjectId(entId,ss);
acdbOpenObject(pEnt,entId,AcDb::kForNotify);
pBlockRecord->appendAcDbEntity(entId,pEnt);
//pCircle->close();
acedSSFree(ss);
AcDbAttributeDefinition *pAttdef = new AcDbAttributeDefinition;
pAttdef->setPosition(basepoint);
pAttdef->setHeight(10);
pAttdef->setRotation(0);
pAttdef->setHorizontalMode(AcDb::kTextLeft);
pAttdef->setVerticalMode(AcDb::kTextBase);
pAttdef->setPrompt("prompt");
pAttdef->setTextString("DEFAULT");
pAttdef->setTag("Tag");
pAttdef->setInvisible(Adesk::kFalse);
pAttdef->setVerifiable(Adesk::kFalse);
pAttdef->setPreset(Adesk::kFalse);
pAttdef->setConstant(Adesk::kFalse);
pAttdef->setFieldLength(Adesk::kFalse);
pBlockRecord->appendAcDbEntity(entId,pAttdef);
pAttdef->close();
pBlockRecord->close();
pBlockTable->close();
