char szSavePath[_MAX_PATH]="",szSelePath[_MAX_PATH]="";
LPITEMIDLIST m_SelectedDir; GetCurrentDirectory(_MAX_PATH, szSavePath);

BROWSEINFO info;
info.hwndOwner = NULL;
info.pidlRoot = NULL;
info.pszDisplayName =NULL;
info.lpszTitle = "选择系统数据的存储目录";
info.ulFlags = BIF_RETURNONLYFSDIRS;
info.lpfn = NULL;
info.lParam = NULL;
info.iImage = NULL;
m_SelectedDir = SHBrowseForFolder(&info);
CString path;
SHGetPathFromIDList(m_SelectedDir,szSavePath);
if(m_SelectedDir!=NULL){
SetDlgItemText(IDC_DATAPATH,szSavePath);
}
