在MFC编程中经常会需要用到选择目录和选择文件的界面，以下总结一下本人常用的这两种对话框的生成方法：

选择目录对话框

// 选择目录按钮

void ?CDcPackerDlg::OnBnClickedDecgen()????

{

????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");???

}

选择文件对话框

CString?CDcPackerDlg::BootOpenDialog()??? // 返回选择的文件名称

{

????CString?strFile?=?_T("");

????CFileDialog????dlgFile(TRUE,?NULL,?OFN_HIDEREADONLY,?_T("Describe?Files?(*.cfg)|*.cfg|All?Files?(*.*)|*.*||"),?NULL);

????if?(dlgFile.DoModal())

????

{

????????strFile?=?dlgFile.GetPathName();

????}

????return?strFile;

}

// 加载文件按钮

void ?CDcPackerDlg::OnBnClickedSelectdec()

{

????//?TODO:?Add?your?control?notification?handler?code?here

????m_strDescPath?=?"";????????//类的成员变量

????//"打开文件"对话框，选择文件，返回其路径

????m_strDescPath?=?BootOpenDialog();

????

}
