ifstream og ofstream?

Det bliver et gæt: du har ikke lukket filen efter at du har
skrevet inden du åbner den igen for at læse.

void save(void)
    {
        cfg_file = "flamegl.cfg";
        write.open (cfg_file);
        write <<  "wallhack "    << (int)wallhack    << endl;
        write <<  "entity "        << (int)entity        << endl;
        write <<  "modalwire "    << (int)modalwire    << endl;
        write <<  "crosshair "    << (int)crosshair    << endl;
        write <<  "mouse2 "        << (int)mouse2        << endl;
        write <<  "lambert "    << (int)lambert        << endl;
        write <<  "Credits "    << (int)Credits        << endl;
        write.close(); // <--------------------
    }

Og tilsvarende skal read også closes.

Det har ikke hjulpet noget at sætte en close på overhovedet!

Kalder du overhovedet read, hvis ja indsæt nogle passende cout/messagebox fx.

void load(void) {
  cfg_file = "flamegl.cfg";
  read.open (cfg_file);
// checker du for om filen er åben??? hvad nu hvis den ikke findes???
  cout << "load" << endl;
  while (read >> variable >> value) {
    cout << variable << value << endl;
            if (!strcmp(variable, "wallhack"))  { wallhack = (int)value; }
            if (!strcmp(variable, "entity"))    { entity = (int)value; }
            if (!strcmp(variable, "modalwire")) { modalwire = (int)value; }
            if (!strcmp(variable, "crosshair")) { crosshair = (int)value; }
            if (!strcmp(variable, "mouse2"))    { mouse2 = (int)value;    }
            if (!strcmp(variable, "lambert"))  { lambert = (int)value;    }
            if (!strcmp(variable, "Credits"))  { Credits = (int)value;    }     
            read.close();
        }
    }

Den her version (med de angiven rettelser) virker hos mig:

#include <iostream>
#include <fstream>
#include <cstring>

using namespace std;

int wallhack, entity, modalwire, crosshair, mouse2, lambert, Credits;

char buf[100];
