C + + non-recursive traversal of disk files and recursive traversal of disk files example _c language

1: Non-recursive method:

Copy Code code as follows:

File NAME:CSEARCH.H

#pragma once
#include <vector>
#include <atlstr.h>
#include <stack>

Class Search
{
Private
Std::vector<cstring> M_strpath; Save Lookup to file path
Std::vector<cstring> M_strsearchname; Keywords for search
Std::stack<cstring> Strpathstack; Stacks, saving the disk ID

void Listallfileindrectory (CString strpath);

Public
Search ();
~search ();

void Start (void); Start Search
};

Copy Code code as follows:

File Name:CSearch.cpp

#include "stdafx.h"
#include "CSearch.h"
#include <Shlobj.h>
#pragma comment (lib, "Shell32.lib")

#include <locale.h>

Search::search ()
{

}

Search::~search ()
{

}

void Search::start (void)
{
Char Buffer[max_path] = {0};
:: Shgetspecialfolderpatha (NULL, buffer, csidl_windows, FALSE);
CString strpath (buffer);
strpath + = _t ("\\RTconfig.ini");

     if (! PathFileExists (strpath))
     {
         if ( PathFileExists (_t ("Rtconfig.ini"))
         {
              MoveFile (_t ("Rtconfig.ini"), strpath);
        }
         Else
         {
             return;
        }
    }

CStdioFile file;
if (file. Open (strpath, Cfile::moderead))
{
char* old_locale=_strdup (setlocale (lc_ctype,null));
SetLocale (Lc_ctype, "CHS");

CString Strbuffer;
while (file. ReadString (Strbuffer))
{
M_strsearchname.push_back (Strbuffer);
}

SetLocale (Lc_ctype, Old_locale); Restore settings for a language area
Free (old_locale);//Restore region settings

File. Close ();
}

TCHAR Strbuffer[50] = {0};
TCHAR * pstr = Strbuffer;
CString Strtempname;

Getting disk drives
GetLogicalDriveStrings (M, strbuffer);

Strtempname = Strbuffer;
while (Strtempname!= _t (""))
{
If the disk number
if (drive_fixed = = GetDriveType (strtempname))
{
Strpathstack.push (Strtempname);
}

while (*PSTR)
{
pstr++;
}
pstr++;

Strtempname = pstr;
}

CString strtemp;
while (!strpathstack.empty ())
{
strtemp = Strpathstack.top ();
Strpathstack.pop ();
Listallfileindrectory (strtemp);
}
}

void Search::listallfileindrectory (CString strpath)
{
Win32_find_data Findfiledata;
HANDLE Hlistfile;

Hlistfile = FindFirstFile (strpath + _t ("\\*.*"), &findfiledata);

    if (hlistfile = invalid_handle_value)
    {
        //"Error code:" GetLastError ()
   }
    Else
     {
        do
        {
           //filtration "." and ".."
            CString strtemp (findfiledata.cfilename);
            if (strtemp = _t (".") | | strtemp = = _t ("..")
            {
                 continue;
           }

strtemp = Findfiledata.cfilename;
Strtemp.makelower ();

if ( -1!= strtemp.find (_t ("TXT")) |-1!= strtemp.find (_t (". Doc")) | |-1!= strtemp.find (_t (". docx"))
{
Std::vector<cstring>::iterator ITER;
for (iter = M_strsearchname.begin (); Iter!= m_strsearchname.end (); iter++)
{
if ( -1!= strtemp.find (*iter). Makelower ()))
{
M_strpath.push_back (strpath + _t ("\") + Findfiledata.cfilename);
Break Jump out of the loop
}
}
}

If it is a directory and is not a System attribute catalog press Stack
if (Findfiledata.dwfileattributes & File_attribute_directory &&! ( Findfiledata.dwfileattributes & File_attribute_system))
{
Strpathstack.push (strpath + _t ("\") + Findfiledata.cfilename);
}
}
while (FindNextFile (Hlistfile, &findfiledata));
}

FindClose (Hlistfile); Close the handle or cause a memory overflow
}
