前段时间有篇名叫《编程日记(1)ARX中如何insert一个图》的文章怎么没看见了？？还有我按照上面的思路写了一段程序，但是插入后，当前窗口中没有我所插入的图形！请指教！！
程序代码如下：
void InsertBlock()
{
char bName,pfName;
int es;
AcGePoint3d Pt(0,0,0);
double Angle = 0.0;
AcGeScale3d XrefScale(1,1,1);
strcpy(bName,"first");
strcpy(pfName,"F:\\FENGH\\program\\AutoCAD\\ObjectARX\\LibMag\\libmag.dwg");
AcDbDatabase *pDbMS = new AcDbDatabase(Adesk::kFalse);
if(pDbMS->readDwgFile(pfName) != Acad::eOk)
{
acutPrintf("\nThe file %s cannot be opend",pfName);
return;
}
// pDbMS->getBlockTable(pBlockTable,AcDb::kForRead);
// pBlockTable->close();
AcDbDatabase * curpDb = acdbHostApplicationServices()->workingDatabase();
AcDbObjectId blockId;
if((es = curpDb->insert(blockId, bName,pDbMS, true)) == Acad::eOk) //´ÓÊý¾Ý¿â²åÈëͼ¿âÖÐ
{
acutPrintf("\ninsert ok\n");
}
else
{
AfxMessageBox("Insert failed");
delete pDbMS;
return;
}
AcDbBlockReference *pBlkRef = new AcDbBlockReference; //´´½¨Ò»¸ö¿é±íÒýÓÃ
pBlkRef->setBlockTableRecord(blockId);// Ö¸ÏòblockId;
pBlkRef->setPosition(Pt);//ÉèÖÃλÖÃ

pBlockTable->close();

pBlockTableRecord->close();
// delete pDbMS;

AcGePoint3d basePoint(-25,-10,0);

InsertBlockWithAttributes("A00",basePoint,0.0,scale); 运行InsertDwgFile()后,得到一个ID,创建一个AcDbBlockReference, 并将它指向ID所代表的AcDbBlockRecord, 然后将这个AcDbBlockReference加入pDb所代表的图形数据库中.
你的程序中,得到ID后,没有操作这个ID.
