Reading a c:\directory with C++

[Nobody/Anonymous]

Hi. Do any of guys hava a small example on how to read a directory with C++?

No, but I do know how to read it using the win32 api:FindFirstFile, FindNextFile. I use it to read a whole CD into a database. Too long code to paste here.

Try this,

#include <stdio.h>
#include <conio.c>
#include <conio.h>
#include <iostream.h>
#include <fstream.h>
#include <string>

void read()

{

ifstream OpenFile("c:\\your file.txt");

char ch;

while(!OpenFile.eof())

{

OpenFile.get(ch);

cout << ch;

}

OpenFile.close();
getche();

}

Well the solution #include <stdio.h>
#include <conio.c>
#include <conio.h>
#include <iostream.h>
#include <fstream.h>
#include <string>

void read()

{

ifstream OpenFile("c:\\your file.txt");

char ch;

while(!OpenFile.eof())

{

OpenFile.get(ch);

cout << ch;

}

OpenFile.close();
getche();

}

Just reads a character from a file. I want to read the filenames from the harddesk.

Ok, I'll try to paste some code here, let's see what happens, I hope the sourceforge server does not reboot.
It's part of my program, you should remove some stuff from it (like Berkely DB inserts). It's complicated, because dir names and files names must be separated.

BOOL fnImportFiles(char *aktualis)
{

HANDLE          FindHandle;
WIN32_FIND_DATA FindData;
char            DirectoryName[MAX_PATH];
char            DirNameW1[MAX_PATH];
char            DirNameW2[MAX_PATH];
char datawork[50]="";
char keywork[255];
DBT key, data;
int ret;
memset(&key, 0, sizeof(key));
memset(&data, 0, sizeof(data));
key.size = 255; 
data.data = datawork;
data.size = 50;

//  Set the new current directory

SetCurrentDirectory( aktualis );

FindHandle = FindFirstFile( "*.*", &FindData );
//    If it is a real directory
if (( FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY ) &&
      ( strcmp(FindData.cFileName, "..") && strcmp(FindData.cFileName, ".") ) )
{
      //       Get the current directory
      GetCurrentDirectory( MAX_PATH, DirectoryName );
      //       Put a "\&quot; if necessary
      if ( strncmp( &DirectoryName[strlen(DirectoryName)-1], "\\&quot;, 1 ) )
           (void) strcat( DirectoryName, "\\&quot; );

      //       Create a new path
      (void) strcat( DirectoryName, FindData.cFileName );
      fnImportFiles(DirectoryName);

      //       Go back one level
      SetCurrentDirectory( ".." );
}
else
{
      if (( strcmp(FindData.cFileName,"..")==0)||( strcmp(FindData.cFileName,".")==0))
            ;
      else
      {
            GetCurrentDirectory( MAX_PATH, DirNameW1 );
            if ( strncmp( &DirNameW1[strlen(DirNameW1)-1], "\\&quot;, 1 ) )
                (void) strcat( DirNameW1, "\\&quot; );
            strcpy(DirNameW2, szVolume);
            strcat(DirNameW2, strstr(DirNameW1, ":"));
            strcat(DirNameW2, FindData.cFileName);
            strncpy(keywork, strlwr(DirNameW2), 255);
            key.data = keywork;
               if ((ret = hdb4->put(hdb4, NULL, &key, &data, DB_NOOVERWRITE)) == 0)
                    ;  
            else
                    return FALSE;
   
      }
}

//  loop to get all inside the current directory
while ( FindNextFile( FindHandle, &FindData ) )
{
        //    If it is a real directory
        if (( FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY ) &&
                    ( strcmp(FindData.cFileName, "..") && strcmp(FindData.cFileName, ".") ) )
           {
            //       Get the current directory
            GetCurrentDirectory( MAX_PATH, DirectoryName );

            //       Put a "\&quot; if necessary
            if ( strncmp( &DirectoryName[strlen(DirectoryName)-1], "\\&quot;, 1 ) )
            (void) strcat( DirectoryName, "\\&quot; );

            //       Create a new path
            (void) strcat( DirectoryName, FindData.cFileName );
            //       Make a new call to itself
            fnImportFiles( DirectoryName );

            //       Go back one level
            SetCurrentDirectory( ".." );

        }
        else
        {
            if (( strcmp(FindData.cFileName,"..")==0)||( strcmp(FindData.cFileName,".")==0))
                ;
            else
            {
                GetCurrentDirectory( MAX_PATH, DirNameW1 );
                if ( strncmp( &DirNameW1[strlen(DirNameW1)-1], "\\&quot;, 1 ) )
                    (void) strcat( DirNameW1, "\\&quot; );
                strcpy(DirNameW2, szVolume);
                strcat(DirNameW2, strstr(DirNameW1, ":"));
                strcat(DirNameW2, FindData.cFileName);
                strncpy(keywork, strlwr(DirNameW2), 255);
                key.data = keywork;
                if ((ret = hdb4->put(hdb4, NULL, &key, &data, DB_NOOVERWRITE)) == 0)
                        ;  
                else
                        return FALSE;
   
            }
        }

    } // End while

    // End the search to this call
    (void) FindClose( FindHandle );
    return TRUE;
