VC 实现资源管理器左边的树形结构

[paodan]

如何实现资源管理器左边的树形结构啊，怎么把“桌面”和“我的电脑”放到树形控件中，还有那些图标，谢谢

[DavidHsing]

现成的，CMFCShellTreeCtrl，
需要 VS2008 sp1，
什么都不用你操心。

CMFCShellTreeCtrl 在MSDN 的2008 SP1中没发现

[paodan]

我实在VC6环境下的

hoho，RP 问题，
你找一下 Microsoft sp1 的 "NewControls" 示例程序，
就有 CMFCShellTreeCtrl 等一套 Shell 组件。

BCG是什么啊，还是自己写代码实现才能锻炼更多，希望能够给我一个比较传统的方法啊

刚写了一个，明天早上给你源码，电脑没带回家：（

呵呵，这个问题比较麻烦

假如是对话框的你新建一个CDirTreeCtrl类继承CTreeCtrl，头文件DirTreeCtrl.h 如下

#if !defined(AFX_DIRTREECTRL_H__80A4D0AB_0840_4000_AEE1_19E003A9D268__INCLUDED_)
#define AFX_DIRTREECTRL_H__80A4D0AB_0840_4000_AEE1_19E003A9D268__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
// DirTreeCtrl.h : header file
//

}

然后在对话框类中关联一个树形控件变量

CDirTreeCtrl m_tree;

在对话框类的OnInitDialog函数中调用

m_tree.Initialize();//调用初始目录树函数

即可
