我是新手,望各位兄弟帮我看看,这段程序片有什么问题?谢谢了!

 AcDbDatabase* pOldDb = acdbHostApplicationServices()->workingDatabase();
 AcDbDatabase* pNewDb = new AcDbDatabase();
 acdbHostApplicationServices()->setWorkingDatabase(pNewDb);

 ''''''//执行数据写入操作
 
 pNewDb->saveAs(_T("RouteTable.dwg"));
 acdbHostApplicationServices()->setWorkingDatabase(pOldDb);
 delete pNewDb;

编绎是没问题的,但在加载ARX后,执行此段,报错,访问拒绝,,,

我把pNewDb->saveAs(_T("RouteTable.dwg"));注释掉后,运行没反映,但是什么文件也没生成.

你粘贴的啊 ！我在这里写的，没有运行，应该没有问题。

void xb()
{
AcDbDatabase *pDb=new AcDbDatabase();
AcDbBlockTable *pBlkTb;
pDb->getSymbolTable(pBlkTb,AcDb::kForRead);
AcDbBlockTableRecord *pBlkTbRcd;
pBlkTb->getAt(ACDB_MODEL_SPACE,pBlkTbRcd,AcDb::kForWrite);
pBlkTb->close();
AcDbCircle *pCircl=new AcDbCircle(AcGePoint3d(1,1,1),AcGeVector3d(0,0,1),1.0);
AcDbCircle *pCirc2=new AcDbCircle(AcGePoint3d(4,4,4),AcGeVector3d(0,0,1),2.0);
pBlkTbRcd->appendAcDbEntity(pCircl);
pBlkTbRcd->appendAcDbEntity(pCirc2);
pCircl->close();
pCirc2->close();
pBlkTbRcd->close();
pDb->saveAs("tt.dwg");
delete pDb;

}
