something wrong with AcdbDatabase::readDWGFile

[Anonymous]

            AcDbDatabase *pDb = new AcDbDatabase(Adesk::kFalse);
            if ( Acad::eOk == pDb->readDwgFile(szBlockPath) )
            {
                acdbHostApplicationServices()->workingDatabase()->insert(blockId, szBlockName, pDb, false);
            }
            delete pDb;

"szBlockPath" is the absolute path of a dwg File. I run the code above in an arx aplication.  after this,  the dwg file of "szBlockPath"  can't be opened again in the cad, the error msg says it has been opened . I want to know whether the code above has lost some code for releasing the dwg from the cad main process memory.

Try calling AcDbDatabase::closeInput(true) to close the file.

Just starting to get into ObjectARX but have done some coding with .NET api but could preserveSourceDatabase  being false be cause the problem?
