mfc中读取文件显示在list控件中
我建了个list控件，还有个button按钮，想实现点击按钮后当前目录下名为“共享文件夹”的信息显示在list中。
程序如下：
// findfileDlg.cpp : implementation file
//
#include "stdafx.h"
#include "findfile.h"
#include "findfileDlg.h"
#define MAX_COUNT 1024
//#define MAX_PATH 256
struct OLDPATH
{
char m_oldpath[MAX_PATH];
};
OLDPATH oldpath[10]; //记录上一层文件读取的路径
char m_flpath[MAX_PATH]; //记录当前文件读取的路径
CButton m_FileBack;//声明返回上一层控件对象
CListCtrl m_filelist; //声明listctrl控件对象
int m_count[MAX_COUNT]; //用来记录共享文件夹下子文件夹在listctrl控件中显示的行号
int layernum; //用来记录查询的是第几层
char* des;
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

没有错误，但就是不能实现。哪位能帮我改一下,谢谢！
