#include<vector>
using namespace std;
void TraverseDir(CString& dir, std::vector<CString>& vec)
{
        CFileFind ff;
        if (dir.Right(1) != "\\")
    {
        dir += "\\";
    }
        dir+="*.*";
        BOOL ret = ff.FindFile(dir);
        while (ret)
    {
        ret = ff.FindNextFile();
        if (ret != 0)
        {if(ff.IsDirectory()&& !ff.IsDots())
        {
            CString path = ff.GetFilePath();
            TraverseDir(path,vec);
        }
        else if (!ff.IsDirectory() && !ff.IsDots())
        {
            CString name=ff.GetFileName();
            CString path = ff.GetFilePath();
            vec.push_back(path);
        }
        }
    }
}
   
用到第二个里面去：

void CmmmmDlg::OnBnClickedButton1()
{
    CString m_path;
    TCHAR pszPath[MAX_PATH];
    BROWSEINFO bi;   
    bi.hwndOwner      = this->GetSafeHwnd();  
    bi.pidlRoot       = NULL;  
    bi.pszDisplayName = NULL;   
    bi.lpszTitle      = TEXT("请选择文件夹");   
    bi.ulFlags        = BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT;  
    bi.lpfn           = NULL;   
    bi.lParam         = 0;  
    bi.iImage         = 0;   
    LPITEMIDLIST pidl = SHBrowseForFolder(&bi);  
    if (pidl == NULL)  
    {  
        return;  
    }  

    if (SHGetPathFromIDList(pidl, pszPath))  
    {  
        //AfxMessageBox(pszPath);  

        m_path = pszPath;
    }     
}
