How to insert frame from library to Document?

Below the code to open and paste a data from first postion in library to document, it is not working fine  

InterfacePtr<ILibrary> PtrLibrary;

          IDFile sysFile;

          std::string path = "/Users/Arun/Desktop/Library.indl";

          sysFile.SetPath(WideString(path.c_str()));

//PtrLibrary->Create(sysFile,NULL);

InterfacePtr<ILibraryCmdUtils> libcmdUtils(ILibraryCmdUtils::QueryLibraryCmdUtils());

          if(libcmdUtils == NULL)

  break;

          InterfacePtr<ICommand> openlibcmd(libcmdUtils->CreateLibraryOpenLibCmd(sysFile));

          if(openlibcmd == NULL)

  break;

          CmdUtils::ProcessCommand(openlibcmd);

  AssetIDListid;// = libcmdUtils1->GetAssetList();

                    libcmdUtils->ProcessLibraryPlaceItemsCmd(id[0],PtrLibrary,ac->GetContextDocument());

Can any one correct me. if any thing wrong...
