MFC 获取listbox所有内容

添加事件处理函数

CString str;
  int nCount = m_listbox.GetSelCount();
  cout << "ncount=" << nCount << endl;
  int* SelIndex = new int[nCount];
  m_listbox.GetSelItems(nCount, SelIndex);//现在selindex数组里面就是你要的行的索引
  m_vec.clear();
  for (int i = 0; i < nCount; i++)
  {
    m_listbox.GetText(SelIndex[i], str);
  //  cout << str.GetBuffer() << endl;
    m_vec.push_back(str.GetBuffer());
  }
  for each (auto var in m_vec)
  {
    cout << var << endl;
  }
  
  delete[]SelIndex;
