you can try something like

Code: [Select]

    ObjectId idb;
    AcDbObjectId ida;

    ida.setFromOldId(idb.OldId);
    idb = ObjectId(ida.asOldId());

//or

    ObjectId idc((long)(AcDbStub*)ida);
    AcDbObjectId idd(reinterpret_cast<AcDbStub*>(idc.OldId));

another way

Code: [Select]

    Editor^ ed = Application::DocumentManager->MdiActiveDocument->Editor;
    Database ^pDb = Application::DocumentManager->MdiActiveDocument->Database;
    AcDbObjectId ide = *reinterpret_cast<AcDbObjectId*>(&(pDb->CurrentSpaceId));

    ed->WriteMessage(pDb->CurrentSpaceId.ToString());
    acutPrintf(_T("\n%ld"), ide.asOldId());

Daniel is god !

Code: [Select]

    ObjectId idb;
    AcDbObjectId ida;

    ida.setFromOldId(idb->OldId);
    idb = ObjectId(ida.asOldId());

from mgdinterop.h:

Code: [Select]


#define GETOBJECTID(id)     (*reinterpret_cast<AcDbObjectId*>(&(id)))

inline Autodesk::AutoCAD::DatabaseServices::ObjectId ToObjectId(const AcDbObjectId& pt)
{
    Autodesk::AutoCAD::DatabaseServices::ObjectId ret;
    GETOBJECTID(ret) = pt;
    return ret;
}
