最近看了《VC++技术内幕》，做些源代码的简要摘抄（2）

 各种常用控件的使用就不做摘抄了，

感觉随用随查就行，以后如果天天用了，那就要熟悉了。

1. 继承CFileDialog
.h

#pragma once

// CSpecialFileDialog dialog

class CSpecialFileDialog : public CFileDialog
{
 DECLARE_DYNAMIC(CSpecialFileDialog)

public:
 CString m_strFilename;
 BOOL m_bDeleteAll;

// Construction
public:

  LPCTSTR lpszDefExt = NULL,

  LPCTSTR lpszFilter = NULL,

 virtual ~CSpecialFileDialog();

// Dialog Data
 enum { IDD = IDD_FILESPECIAL };

protected:
