[ARX]大家帮忙看一下这段程序

为什么我调用了该函数,插入的图块显示不出来的,是什么原因!


谢谢

我也是个菜鸟不知道我说的对不对，你的代码第一个if语句： if(es==Acad::eOk)
{
AfxMessageBox("readDwgFile Successful!");
return;
}
如果成功读入了ccd.dwg文件则readDwgFile的返回值是Acad::eOk，由于return 语句的作用是不是就退出了该函数，而后面的语句根本就没有执行，你把这个if语句删掉试试

不关上面的事,我把上面的屏蔽掉也是这个样了,还请大家帮一下忙!

Acad::ErrorStatus es = Acad::eOk;
//获得数据库指定块的ID
AcDbBlockTable *pBTR;
es = pBackDb->getBlockTable(pBTR,AcDb::kForRead);
AcDbObjectId blkId;
es = pBTR->getAt(BlockId,blkId);
pBTR->close();
//将指定的块插入到一个新的数据库
AcDbDatabase *pNewDb = NULL;
es = pBackDb->wblock(pNewDb,blkId);
delete pBackDb;
//将新的数据库插入到当前数据库中形成一个新的块
AcDbObjectId newBlkId;
es = acdbCurDwg()->insert(newBlkId,BlockId,pNewDb,false);
delete pNewDb;

把你 es = acdbHostApplicationServices()->workingDatabase()->insert (blockId, "myfile", pDwg,
Adesk::kFalse) ;
if ( es != Acad::eOk )
acutPrintf ("\n插入块错误.") ;
delete pDwg ; 换成上面的,你自己再检查一下

你只是插入了块，还需要进行块引用 AcDbObjectId idBlock;
AcDbBlockReference* pBlock=new AcDbBlockReference;
pBlock->setPosition(ptCenter);
pBlock->setLayer(m_idLineLayer);
pBlock->setBlockTableRecord(idBlock);
pBlock->setScaleFactors(AcGeScale3d(m_dPlotScale));
idArray.append(CLjDwg::AddEntity(pBlock));
pBlock->close();
