问几个关于表格控件和datagird的问题。

Question

1，大家在用VC编程的时候，都用什么控件显示表格？
         看到有人用List,不过这个支持的功能应该比较少，而且可视化的功能比较少，至少比datagird少多了。2，用datagird显示表格的话，msdn给出了一段C++代码，由于代码太长，我把代码专门放在一楼了。
其中，前面的
#using <system.dll>
#using <system.data.dll>
#using <system.drawing.dll>
#using <system.windows.forms.dll>
#using <system.xml.dll>using namespace System;
using namespace System::ComponentModel;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::Windows::Forms;这些东西似乎是要引入dll，并且定义明明空间。但在VC6.0中却编译通不过，把#using换成#import也是不行的。压根就提示找不到system.dll。
在这里问下，该段代码如何才能正确的运行出来。3，跟2差不多是同一个问题。datagird是netframe的插件，关联到几个很重要的类：dataset,dataview,datatable等，比如我要手工在datagird里面插入一行，需要用datatable.Column.Add()这个方法，但现在的问题是，这几个类都不可识别，是因为他们在那些命名空间里面？还是有其他原因？

Answer 3

我现在貌似猜到那个为什么不能用了。貌似是因为那个是VC++.NET的代码？

Answer 4

CListCtrl，还见过有嵌入html页的lz换最新的SDK试试？
