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

void CBianLiDlg::OnSelectFolder()
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedBlock.gif...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif CString str;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif BROWSEINFO bi;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif char name[MAX_PATH];
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif ZeroMemory(&bi,sizeof(BROWSEINFO));
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif bi.hwndOwner = GetSafeHwnd();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif bi.pszDisplayName = name;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif bi.lpszTitle = "Select folder";
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif //bi.ulFlags = BIF_USENEWUI;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif bi.ulFlags = BIF_RETURNFSANCESTORS;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif LPITEMIDLIST idl = SHBrowseForFolder(&bi);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif if(idl == NULL)
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif return;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif SHGetPathFromIDList(idl, str.GetBuffer(MAX_PATH));
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif str.ReleaseBuffer();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif m_root = str;//为对话框中与一编辑框对应的CString型变量，保存并显示选中的路径。
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif if(str.GetAt(str.GetLength()-1)!='/')
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif m_root+="/";
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif UpdateData(FALSE);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedBlockEnd.gif }

void CBianLiDlg::FileSearch(CString root)
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedBlock.gif...{ // root 为目录名
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif CFileFind ff;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif CString FilePath;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif if (root.Right(1)!="/")
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedSubBlock.gif ...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif root+="/";
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedSubBlockEnd.gif }
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif root+="*.*";
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif BOOL res=ff.FindFile(root);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif while (res)
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedSubBlock.gif ...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif res=ff.FindNextFile();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif FilePath=ff.GetFilePath();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif if (ff.IsDirectory() && !ff.IsDots())// 找到的是文件夹
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedSubBlock.gif ...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif FileSearch(FilePath);// 递归
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedSubBlockEnd.gif }
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif else if (!ff.IsDirectory() && !ff.IsDots())// 找到的是文件
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedSubBlock.gif ...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif m_ff+=FilePath;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif m_ff+=" ";
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedSubBlockEnd.gif }
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedSubBlockEnd.gif }
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedBlockEnd.gif }

多文件选择

CFileDialog Dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT|OFN_ALLOWMULTISELECT);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif if(Dlg.DoModal()==IDOK)
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedBlock.gif ...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif POSITION pos = Dlg.GetStartPosition();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif while(pos)
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedSubBlock.gif ...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif CString szFileName = Dlg.GetNextPathName(pos);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif AfxMessageBox(szFileName);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedSubBlockEnd.gif }
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedBlockEnd.gif }

选择文件对话框

http://www.cppblog.com/Images/OutliningIndicators/None.gifCString CDcPackerDlg::BootOpenDialog() //返回选择的文件名称
http://www.cppblog.com/Images/dot.gif{
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif CString strFile = _T("");
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif CFileDialog dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.cfg)|*.cfg|All Files (*.*)|*.*||"), NULL);
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif if (dlgFile.DoModal())
http://www.cppblog.com/Images/OutliningIndicators/ContractedSubBlock.gif http://www.cppblog.com/Images/dot.gif{
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif strFile = dlgFile.GetPathName();
http://www.cppblog.com/Images/OutliningIndicators/ExpandedSubBlockEnd.gif }
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif return strFile;
http://www.cppblog.com/Images/OutliningIndicators/ExpandedBlockEnd.gif }
http://www.cppblog.com/Images/OutliningIndicators/None.gif
http://www.cppblog.com/Images/OutliningIndicators/None.gif//加载文件按钮
http://www.cppblog.com/Images/OutliningIndicators/None.gifvoid CDcPackerDlg::OnBnClickedSelectdec()
http://www.cppblog.com/Images/dot.gif{

http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif //"打开文件"对话框，选择文件，返回其路径
http://www.cppblog.com/Images/OutliningIndicators/InBlock.gif m_strDescPath = BootOpenDialog();
