这是在网上找到代码，，做的实验，，为什么在导入LISTVIEW里，，显示的是一排排数字，，都是NO1，NO2这样的形式，，不是EXCEL里面的内容，，求教
[解决办法]
和excel无关，这段代码有问题，这样写也是NO1，NO2这样的形式
   ListView1->Clear();
for(int i=0;i<10;i++) // 遍历所有行
  {
  ListView1->Items->Add();
  ListView1->Items->Item[i]->Caption="No"+IntToStr(i);
  ListView1->Items->Item[i]->SubItems->Add("a");
  ListView1->Items->Item[i]->SubItems->Add("b");
  ListView1->Items->Item[i]->SubItems->Add("c");
  ListView1->Items->Item[i]->SubItems->Add("d");
  ListView1->Items->Item[i]->SubItems->Add("否");
  }
