[arx]c++编译无错 cad非正常退出（附图）
[arx]c++编译无错 cad非正常退出（附图）
我的程序如下：
ads_point pt;
int nodenumcount; //定义节点数，即最大的节点编号数值
acedgetint("请输入多边形顶点数:",&nodenumcount);
if(acedgetpoint(null,"\n请选择起始点:",pt)==rtnorm)
{
xpt[0].format("%g",pt[x]);
ypt[0].format("%g",pt[y]);
acutprintf("\n起始点坐标为:%s,%s",xpt[0],ypt[0]);
}
xco[0]=atof(xpt[0]);
yco[0]=atof(ypt[0]);
for(int i=0;i<nodenumcount;i++)
{
if(acedgetpoint(null,"\n拾取下一点:",pt)==rtnorm)
{
xpt[i+1].format("%g",pt[x]);
ypt[i+1].format("%g",pt[y]);
acutprintf("\n该点坐标为:%s,%s",xpt[i+1],ypt[i+1]);
}
xco[i+1]=atof(xpt[i+1]);
yco[i+1]=atof(ypt[i+1]);
//pick点，连续画直线
acdbblocktablerecord *pblktablercd
=new acdbblocktablerecord();//创建块表记录
//以写方式得到当前块表的指针
acdbblocktable *pblktable=null;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(pblktable, acdb::kforwrite);
//将新的块表记录加入块表中，并获得块表记录的id
acdbobjectid id;
pblktable->add(id, pblktablercd);
pblktable->close();
//生成直线
acgepoint3d startpt(xco[i],yco[i],0.0);//定义直线起点
acgepoint3d endpt(xco[i+1],yco[i+1],0.0);//定义直线终点
acdbline *pline=new acdbline(startpt,endpt);
acdbblocktable *pblktable2=null;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(pblktable2, acdb::kforread);

pblktable2->getat(acdb_model_space, pblktablercd,
acdb::kforwrite);
pblktable2->close();

acdbobjectid lineid;
pblktablercd->appendacdbentity(lineid, pline);
// pline->setlayer("layer_frame");//设置创建轮廓线的层为"layer_frame"

pblktablercd->close();
pline->close();
}
如上是随点画n边形的一段代码，能画n边形，但是退出时会连续弹出两个对话框，
如下：（肯定是上面这段代码的问题，之前也有朋友问过类似的问题，望高手指教）
现在应该搞定了吧^_^
