Load/ Save 어떻게 하나요....아래는 제가 작성한 코드입니다.. 트리만 저장되고 노드데이터는 잘안되네요..제가 먼가 잘못하고 있는듯 한데..쩝..도와주세요

Virtual Treeview에서..

// Unit1.h  노드 선언
typedef struct tagPhonebook {
    AnsiString Name;
    AnsiString Tel;
    AnsiString Sex;
   //    int ImageIndex;         // 출력할 이미지의 index
} structPhonebook, *ptrstructPhonebook;

private :
            AnsiString fName;
// 이하 생략
//-------------------------------------------------------------------------------------

void __fastcall TForm1::VirtualStringTree1LoadNode(TBaseVirtualTree *Sender,  // Load
      PVirtualNode Node, TStream *Stream)
{
    int Size;

    if (!Node)
        return;

    structPhonebook *pPhonebook = (structPhonebook *)Sender->GetNodeData(Node);

    Stream->Read(Node, sizeof(Node));
    Stream->Read(pPhonebook->Name.c_str(), sizeof(pPhonebook->Name+1));
    Stream->Read(pPhonebook->Tel.c_str(), sizeof(pPhonebook->Tel.Length() +1));
    Stream->Read(pPhonebook->Sex.c_str(), sizeof(pPhonebook->Sex.Length()+1));
}
void __fastcall TForm1::VirtualStringTree1SaveNode(TBaseVirtualTree *Sender,  // Save
      PVirtualNode Node, TStream *Stream)
{
    if (!Node)
        return;

    structPhonebook *pPhonebook =(structPhonebook *)Sender->GetNodeData(Node);

    Stream->Write(Node, sizeof(Node));
    Stream->Write(pPhonebook->Name.c_str(), sizeof(pPhonebook->Name+1));
    Stream->Write(pPhonebook->Tel.c_str(), sizeof(pPhonebook->Tel.Length() +1));
    Stream->Write(pPhonebook->Sex.c_str(), sizeof(pPhonebook->Sex.Length()+1));

}


void __fastcall TForm1::SaveClick(TObject *Sender)
{
       fName="tt.txt";
       VirtualStringTree1->SaveToFile(fName)  ;
}
//---------------------------------------------------------------------------


void __fastcall TForm1::LoadClick(TObject *Sender)
{
        fName="tt.txt";
        VirtualStringTree1->LoadFromFile(fName);
}
