C / C++ / MFC

struct Station
{
  CString Name;
  ULONG Number;
  CTime TimeArrivial;
  CTime TimePlannedArrivial;
  ULONG TimeAccuracy;
};
struct Vehicle
{
 CString Name;
 ULONG Circle;
 vector <Station> vStations;
};

vector<Vehicle> vVehicles;
So, i tried to pack it in SafeArray, but i don't know right it or not:
struct saStation
{
  BSTR Name;
  ULONG Number;
  LONG TimeArrivial;
  LONG TimePlannedArrivial;
  ULONG TimeAccuracy;

};
struct saVehicle
{
 BSTR Name;
 ULONG Circle;
 SAFEARRAY *psaStations;
};

then i pack it:
SAFEARRAYBOUD rgsabound[1];
rgsabound[0].cElements = vVehicles.size();
rgsabound[0].lLbound = 0;
SAFEARRAY* pMainArray = SafeArrayCreate(VT_VARIANT,1,rgsabound);
saVehicle* psaVehicles;
SafeArrayAccessData(pMainArray,(void**)&psaVehicles);
for(int i = 0;i<pMainArray->rgsaboud[0].cElement;i++)
{
 psaVehicles[i].Name = vVehicles[i].Name.AllocSysString();
 psaVehicles[i].Circle = vVehicles[i].Circle;
 SAFEARRAYBOUD rgsastationbound[1];
 rgsastationbound[0].cElements = vVehicles[i].vStations.size();
 rgsastationbound[0].lLbound = 0;

 psaVehicles[i].psaStations = SafeArrayCreate(VT_VARIANT,1,rgsastationbound);
 saStation* psaStation;
 SafeArrayAccessData(psaVehicles[i].psaStations,(void**)&psaStation);
 for(int j = 0;j<vVehicles[i].vStations.size();j++)
 {
  //Fill In The psaStation...
  //....
 }
 SafeArrayUnaccessData(psaVehicles[i].psaStations);
}
SafeArrayUnaccessData(pMainArray);
