CFileFind应用，找到文件夹下，所有文件夹。

CString pathOfD2;

std::vector<CString> folder;

std::vector<CString>::iterator it;

CString str;

void CTsCFliedlgDlg::OnBnClickedBtnOpen()

{

  // TODO: 在此添加控件通知处理程序代码

  CFileDialog m_dlg(TRUE,NULL,NULL);

  if (m_dlg.DoModal() == IDOK)

  {
 conStrPath=m_dlg.GetPathName();

  pathOfD2=m_dlg.GetFolderPath();

  CString temp = "\\*.*";

  pathOfD2 += temp;


  CFileFind finder;//详见msdn的应用。

  BOOL bWorking = finder.FindFile(pathOfD2);

  while (bWorking)

  {

    bWorking = finder.FindNextFile();


    // skip . and .. files; otherwise, we'd

    // recur infinitely!


    if (finder.IsDots())

    continue;


    // if it's a directory, recursively search it


    if (finder.IsDirectory())

    {

     str = finder.GetFileTitle();//获取文件夹名

    folder.push_back(str);
     }

  }


  finder.Close();

  }

  
  for (it = folder.begin(); it != folder.end(); it++)

  {

  con_comb1.AddString(*it);//将搜到的文件夹名字的结果添加到ccombobox

  }

  UpdateData(FALSE);

  
}

同理查找文件夹下exe或 任意*.*?

CString pathOfD2;
std::vector<CString> folder;
std::vector::iterator it;
CString str;
void CTsCFliedlgDlg::OnBnClickedBtnOpen()
{
// TODO: 在此添加控件通知处理程序代码
CFileDialog m_dlg(TRUE,NULL,NULL);
if (m_dlg.DoModal() == IDOK)
{
    conStrPath=m_dlg.GetPathName();
    pathOfD2=m_dlg.GetFolderPath();
    CString temp = "\\*.exe";//查找exe
    pathOfD2 += temp;

    CFileFind finder;
    BOOL bWorking = finder.FindFile(pathOfD2);
    while (bWorking)
    {
        bWorking = finder.FindNextFile();

        //// skip . and .. files; otherwise, we'd
        //// recur infinitely!

        //if (finder.IsDots())
        //  continue;

        //// if it's a directory, recursively search it

        //if (finder.IsDirectory())
        //{
        //   str = finder.GetFileTitle();
        //  folder.push_back(str);
        //  
        //}
        str = finder.GetFileName();
        folder.push_back(str);
    }

    finder.Close();
}

for (it = folder.begin(); it != folder.end(); it++)
{
    con_comb1.SetCurSel(0);
    con_comb1.AddString(*it);
}
UpdateData(FALSE);
