MFC实现 打开文件、保存文件

	CString folderName;
	CFileDialog hFileDlg(FALSE, _T("ini"), _T(""), OFN_OVERWRITEPROMPT | OFN_HIDEREADONLY, _T("ini文件|*.ini|所有文件|*||"));
	//首参数FALSE是保存 
	//首参数TRUE 是打开


	//参数设置
	hFileDlg.m_ofn.nFilterIndex = 1;
	hFileDlg.m_ofn.hwndOwner = m_hWnd;
	hFileDlg.m_ofn.lStructSize = sizeof(OPENFILENAME);
	hFileDlg.m_ofn.lpstrTitle = TEXT("保存配置文件...\0");//标题名字
	hFileDlg.m_ofn.nMaxFile = MAX_PATH;
	if (hFileDlg.DoModal() == IDOK)
	{
		folderName = hFileDlg.GetPathName();//获取到保存文件的路径
		UpdateData(FALSE);
	}
	WritePrivateProfileString(_T("system"), _T("type"), _T("1"), folderName);
