求助！创建多个图层的问题
acdbobjectid ccreateent::creatlayer (char layername[100],int nnewcolor,int weight,char linetype[50])
{
// 获得当前图形的层表
acdblayertable *playertbl;
acdbhostapplicationservices()->workingdatabase()

// 创建新的层表记录
acdbobjectid layertblrcdid;
acdblayertablerecord *playertblrcd;

playertblrcd->setname(layername);
accmcolor color;
color.setcolorindex(nnewcolor);
playertblrcd->setcolor(color);
acdb:ineweight lineweight =(acdb:ineweight)weight;
playertblrcd->setlineweight(lineweight);
acdblinetypetable *plinetypetbl;
acdbhostapplicationservices()->workingdatabase()
->getlinetypetable(plinetypetbl, acdb::kforwrite);
acdbobjectid linetypeid;
plinetypetbl->getat(linetype, linetypeid);
playertblrcd->setlinetypeobjectid(linetypeid);
// 将新建的层表记录添加到层表中
playertbl->add(layertblrcdid, playertblrcd);
playertbl->close();
playertblrcd->close();

}
这是 我 编写的 创建图层的 函数，我在调用时如果调用一次 运行可以成功，但当调用2次 或多次的时候 cad就运行错误，请 高手给解决一下！ 谢谢了！
以下我是的调用过程，在下初学者，请多多指教！
char name2[]="02";
char name3[]="03";
char linetype1[]="center";
char linetype2[]="dashed";
char linetype3[]="continuous";
ccreateent::creatlayer(name1,1,0,linetype1);
ccreateent::creatlayer(name2,50,0,linetype2);
ccreateent::creatlayer(name3,100,30,linetype3);
你不是已经解决了?
解决了 我没没有关闭 线性表指针~
另外我改了一下 函数：
acdbobjectid ccreateent::creatlayer (char layername[100],int nnewcolor,
int weight,char linetype[50])
{
// 获得当前图形的层表
acdblayertable *playertbl;
acdbobjectid layertblrcdid;
acdbhostapplicationservices()->workingdatabase()
->getlayertable(playertbl, acdb::kforwrite);
if ((playertbl->getat(layername,layertblrcdid))!=acad::eok)
{
// 创建新的层表记录
acdbobjectid layertblrcdid;
acdblayertablerecord *playertblrcd;
playertblrcd = new acdblayertablerecord();
playertblrcd->setname(layername);
accmcolor color;
color.setcolorindex(nnewcolor);
playertblrcd->setcolor(color);
acdb:ineweight lineweight =(acdb:ineweight)weight;
playertblrcd->setlineweight(lineweight);
acdblinetypetable *plinetypetbl;
acdbhostapplicationservices()->workingdatabase()
->getlinetypetable(plinetypetbl, acdb::kforwrite);
acdbobjectid linetypeid;
plinetypetbl->getat(linetype, linetypeid);
playertblrcd->setlinetypeobjectid(linetypeid);
plinetypetbl->close();
// 将新建的层表记录添加到层表中
playertbl->add(layertblrcdid, playertblrcd);
playertbl->close();
playertblrcd->close();
acutprintf("\n [%s层] 创建成功！",layername);
return layertblrcdid;
}else{
acdbobjectid layertblrcdid;
playertbl->getat(layername,layertblrcdid);
return layertblrcdid;
acutprintf("\n [%s层] 以创建！",layername);
}
}
