1、选择目录对话框：szPath为选择目录路径

char szPath[MAX_PATH];     //存放选择的目录路径     CString str;    ZeroMemory(szPath, sizeof(szPath));       BROWSEINFO bi;       bi.hwndOwner = m_hWnd;       bi.pidlRoot = NULL;       bi.pszDisplayName = szPath;       bi.lpszTitle = "请选择需要打包的目录：";       bi.ulFlags = 0;       bi.lpfn = NULL;       bi.lParam = 0;       bi.iImage = 0;       //弹出选择目录对话框    LPITEMIDLIST lp = SHBrowseForFolder(&bi);       if(lp && SHGetPathFromIDList(lp, szPath))       {        str.Format("选择的目录为 %s",  szPath);        AfxMessageBox(str);            }    else           AfxMessageBox("无效的目录，请重新选择");

2、选择文件对话框：strFile为文件路径

CString strFile = _T("");    CFileDialog    dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.cfg)|*.cfg|All Files (*.*)|*.*||"), NULL);    if (dlgFile.DoModal())    {        strFile = dlgFile.GetPathName();    }    return strFile;

3、获取目录下所有文件名

WIN32_FIND_DATA fd; HANDLE hFind = ::FindFirstFile("C:\\*.*", &fd);if(hFind != INVALID_HANDLE_VALUE){    do    {        printf(fd.cFileName);    }    while(::FindNextFile(hFind, &fd));    ::FindClose(hFind);}

4、获取指定目录下某个类型的所有文件个数和名称，弹出对话框显示

char szPath[MAX_PATH];     //存放选择的目录路径     CString str;    ZeroMemory(szPath, sizeof(szPath));       BROWSEINFO bi;       bi.hwndOwner = m_hWnd;       bi.pidlRoot = NULL;       bi.pszDisplayName = szPath;       bi.lpszTitle = "请选择存放文件的目录：";       bi.ulFlags = 0;       bi.lpfn = NULL;       bi.lParam = 0;       bi.iImage = 0;       //弹出选择目录对话框    LPITEMIDLIST lp = SHBrowseForFolder(&bi);       if(lp && SHGetPathFromIDList(lp, szPath))       {str.Format("%s",  szPath);int f = 0;CString ff;CString file[100];CString add = "";WIN32_FIND_DATA fd;HANDLE hFind = ::FindFirstFile(str + "\\*.txt", &fd);if(hFind != INVALID_HANDLE_VALUE){do{file[f] = fd.cFileName;f++;}while(::FindNextFile(hFind, &fd));for(int i = 0; i < f; i++){add = add + file[i] + "\n";}ff.Format("有%d个数据\n",f);ff+=add;AfxMessageBox(ff);::FindClose(hFind);}    }    else       {AfxMessageBox("无效的目录，请重新选择");  }
