MFC File Operations

 

1. Create the folder createdirectory (% 1, null );
2. Create a cfile file;
File. Open (% 1, cfile: modecreate | cfile: modewrite );
3. Delete the deletefile (% 1 );
4. Delete the folder removedirectory (% 1 );
5. delete all folders in a directory cfilefind finder; cstring path; Path. format ("% s \*. * ", % 1); bool bworking = finder. findfile (PATH );
While (bworking) {bworking = finder. findnextfile (); If (finder. isdirectory () {removedirectory (finder. getfilepath ());}}
6. Clear the folder removedirectory (% 1); createdirectory (% 1, null );
7. Read the file char sread [5120]; cfile mfile (_ T (% 1), cfile: moderead); While (sread! = NULL) {mfile. Read (sread, 5120); cstring % 2 (sread); % 3} mfile. Close ();

8. write File cfile mfile (_ T (% 1), cfile: modewrite | cfile: modecreate); mfile. write (% 2, sizeof (% 2); mfile. flush (); mfile. close ();

10. Read File Attributes DWORD dwattrs = getfileattributes (% 1); If (dwattrs & file_attribute_readonly) {% 2} If (dwattrs & file_attribute_normal) {% 3}

12. enumerate all folders in a directory cfilefind finder; cstring path; Path. format ("% s \*. * ", % 1); bool bworking = finder. findfile (PATH );
While (bworking) {bworking = finder. findnextfile (); If (finder. isdirectory () {cstring % 1 = finder. getfilepath (); % 2 }}

 

 

• 19 on the 7th floor. Copy all the files in one folder to another directory.

  // # Include

  Using STD: string;

  Char Sep = '/';

  # Ifdef _ Win32

  SEP = '\';

  # Endif

  Cfilefind finder;

  Cstring path;

  Path. Format ("% s \ *. *", % 1 );

  Bool bworking = finder. findfile (PATH );

  While (bworking)

  {

  Bworking = finder. findnextfile ();

  If (! Finder. isdirectory () | finder. isdots ()){

  String S (finder. getfilename ());

  Cstring sourcefile (% 1 );

  If (S. rfind (SEP, S. Length ())! = String: NPOs)

  {

  Sourcefile = sourcefile + "//" + S. substr (I + 1, S. Length ()-I );

  Cstring targetfile (S. substr (I + 1, S. Length ()-I ));

  Targetfile = % 2 + "//" + targetfile /;

  Copyfile (sourcefile. getbuffer (0), targetfile. getbuffer (0), true );

  }

  }

  }

  20. Extract Extension

  Cstring path (% 1 );

  Cstring % 2 = path. mid (path. reversefind ('.'));

  21. Extract file name

  Cstring path (% 1 );

  Cstring % 2 = path. mid (path. reversefind ('\') + 1 );

  22. Extract the file path

  Char appname [max_path];

  Getmodualfilename (null, appname, max_path );

  // # Include

  Using STD: string;

  String S (% 1 );

  String newext (% 2 );

  String: size_type I = S. rfind ('.', S. Length ());

  If (I! = String: NPOs)

  S. Replace (I + 1, newext. Length (), newext );

  Cstring % 3 (s );

   

  33. Read INI file attributes cstdiofile INIFILE (% 1, cfile: moderead); cstring Path = INIFILE. getfilepath (); INIFILE.
