Hov, sådan her:

#include <stdio.h>

#include <windows.h>

int main()
{
  WIN32_FIND_DATA data;
  HANDLE h = FindFirstFile("C:\\test\\*.*",&data);
  if(h!=INVALID_HANDLE_VALUE) {
    printf("%s %d %d\n",data.cFileName,data.nFileSizeHigh,data.nFileSizeLow);
    while(FindNextFile(h,&data)) {
        printf("%s %d %d\n",data.cFileName,data.nFileSizeHigh,data.nFileSizeLow);
    }
  }
  FindClose(h);
  return 0;
}

//>Rune

Hmm...
Gider du skrive det i C++ - jeg er ikke så god til det der med printf, da jeg aldrig har kodet C...
Kunne jeg få dig til at bruge cout?

#include <iostream>
#include <windows.h>

int main()
{
  WIN32_FIND_DATA data;
  HANDLE h = FindFirstFile("*.cpp",&data);
  if(h!=INVALID_HANDLE_VALUE)
  {
    do
    {
      std::cout << data.cFileName << " " << data.nFileSizeHigh << " " << data.nFileSizeLow << std::endl;
    }
    while(FindNextFile(h,&data));
  }
  FindClose(h);
  return 0;
}

Er det ikke nemmere med:

#include <iostream>
#include <windows.h>

int main()
{
  WIN32_FIND_DATA data;
  HANDLE h = FindFirstFile("*.cpp",&data);
  while(h!=INVALID_HANDLE_VALUE && FindNextFile(h,&data)
  {
    std::cout << data.cFileName << " " << data.nFileSizeHigh << " " <<
  }
  FindClose(h);
  return 0;
}

?

Hov!
Jeg mener:

#include <iostream>
#include <windows.h>

int main()
{
  WIN32_FIND_DATA data;
  HANDLE h = FindFirstFile("*.cpp",&data);
  while(h!=INVALID_HANDLE_VALUE && FindNextFile(h,&data)
  {
    std::cout << data.cFileName << " " << data.nFileSizeHigh << " " << data.nFileSizeLow << std::endl;
  }
  FindClose(h);
  return 0;
}

Følgende besked kommer når jeg bruger

#include <iostream>
#include <windows.h>
#include "stdafx.h"

int main()
{
  WIN32_FIND_DATA data;
  HANDLE h = FindFirstFile("*.cpp",&data);
  if(h!=INVALID_HANDLE_VALUE)
  {
    do
    {
      std::cout << data.cFileName << " " << data.nFileSizeHigh << " " << data.nFileSizeLow << std::endl;
    }
    while(FindNextFile(h,&data));
  }
  FindClose(h);
  return 0;
}

Jeg tror at du skal have instaleret "platform sdk" fra Microsoft, klick på "Windows Platform SDK" på denne side:

http://msdn.microsoft.com/vstudio/express/visualC/default.aspx

Hvordan installeres det? (Jeg har downloadet det.)

Det komme lidt an på hvad du har downloadet.
Hvis du har downloadet PSDK-FULL.1.cab - PSDK-FULL.16.cab skal du også downloade og køre  PSDK-FULL.exe

Kan man ikke bare downloade en fuld pakke...?

(Jeg har PSDK-FULL.1.cab)

Du kan instalere fra internet på denne side:
http://www.microsoft.com/downloads/details.aspx?familyid=A55B6B43-E24F-4EA3-A93E-40C0EC4F68E5&displaylang=en#filelist

Ellers skal du downloade PSDK-FULL.2.cab - PSDK-FULL.16.cab og PSDK-FULL.exe

Ok, installerer det nu...

Hvad skal jeg vælge?

Hvad skal du vælge hvor?
Hvilke valgmuligheder har du?

PSDK-amd64.exe,
PSDK-ia64.exe og
PSDK-x86.exe.

PSDK-x86.exe, medmindre du har brug for at kunne lave programmer specifikt til 64bit CPU'er.

Ok... Prøver lige...

Den er tung for mit langsomme internet... Men pyt!

HMPH!

Er det koden fra "17/12-2005 10:41:57"?

Hvad står der i linie 12?

Prøv at slette std:: foran cout og endl.

Eller slet #include <stdafx.h> og fortæl kompileren at du ikke vil bruge "precompiled headers"

Undskyld, men jeg har ikke lige fået kikket på det...
Kan du ikke bare smide et svar, bertelbrander?
Så kan i jo dele pointene...
Ved ikke helt, hvornår jeg for taget mig sammen til at fortsætte med C++...
(Har også gang i en hjemmeside, tre spil og en masse rod...)

Jeg samler ikke på point, giv dem til Rune (medions).

Det er måske lettere at bruge Dev-Cpp eller Code::Blocks, der downloader du det hele som én pakke, som ikke fylder ret meget.
