请教遍历的问题

lovelyzhao

问题：构造选择集，获取选择集里的特征点并充放在数组中，然后在比较特征点在数组中的位置。以下是代码，但结果总是不正确，虽然调试是通了。

请各位帮忙，谢谢！

void zhao_rank()
{
 // TODO: Implement the command
 int i,cod_number;
 int j;
 long ilast;
 ads_name ent[256];
 float coordinate[256][3];

 acedSSLength(ssname,&ilast);

 AcDbEntity *pEntity;
 AcDbObjectId objId;
 //*********以下程序是将选择集中实体坐标储存在二维数组***********// 
 for(i=1;i<ilast+1;i++)
 {
  acedSSName(ssname,ilast-i,ent);
  acdbGetObjectId(objId,ent);
  acdbOpenObject(pEntity,objId,AcDb::kForRead);//打开点实体

用AcDbObjectIdArray
