急！请教高手
我编的打断线条的代码，为了测试，再求出交点后，在交点位置生成acdbtext，显示交点序号。命令执行后，如果删除生成的文字，就会出现 scran.cpp!eHadMultipltReader的错误，然后死掉。请教高手到底是啥子问题。代码如下：
Acad::ErrorStatus TOMbreakEnt(ads_name entSrc,ads_name entDis,int &intersectNum)
{
AcDbEntity *pEntSrc,*pEntDis;
AcDbObjectId idSrc,idDis;
if (entSrc==entDis && entSrc==entDis)
return Acad::eInetUnknownError;
if (acdbGetObjectId(idDis,entDis)!=Acad::eOk)
return Acad::eInetUnknownError;
if (acdbOpenObject(pEntDis,idDis,AcDb::kForRead)!=Acad::eOk)
return Acad::eInetUnknownError;
if (!pEntDis->isKindOf(AcDbCurve::desc()) )
return Acad::eInetUnknownError;
if (acdbGetObjectId(idSrc,entSrc)!=Acad::eOk)
return Acad::eInetUnknownError;
if (acdbOpenObject(pEntSrc,idSrc,AcDb::kForRead)!=Acad::eOk)
return Acad::eInetUnknownError;
AcGePoint3dArray aIntersect;
AcGePoint3d or(0,0,0);
AcGeVector3d vx(1,0,0),vy(0,1,0);
AcGePlane pl(or,vx,vy);
ads_name entLast;
ads_point p1;
//pEntDis->intersectWith(pEntSrc,AcDb::kOnBothOperands,pl,aIntersect);
pEntSrc->intersectWith(pEntDis,AcDb::kOnBothOperands,pl,aIntersect);
pEntSrc->close();
pEntDis->close();
if (aIntersect.length()>intersectNum)
intersectNum=aIntersect.length();
AcDbText *pText;
char text;
if (!aIntersect.isEmpty()){
for (long i=aIntersect.length()-1;i>=0;i--){
p1=(aIntersect);
p1=(aIntersect);
p1=(aIntersect);
acedCommand(RTSTR,"_break",RTLB, RTENAME, entDis, RTPOINT, p1, RTLE,RTPOINT,p1,RTNONE);
//测试用代码，如果把文字的插入点改为一样的，比如AcGePoint3d point1
//pText=new AcDbText(point1,text,AcDbObjectId::kNull,1,0)就不会出错了
sprintf(text,"%d",i);
pText=new AcDbText(aIntersect,text,AcDbObjectId::kNull,1,0);
AddEntity(pText);
pText->close();
}
}
return Acad::eOk;
}
acedCommand(RTSTR,"_break",RTLB, RTENAME, entDis, RTPOINT, p1, RTLE,RTPOINT,p1,RTNONE);
you delete this line.maybe error caused because of this line.
try.
good luck! 我解决乐,是有些entdis已经在上层函数中打开了,结果不能调用break打断它
