Ho cercato su internet un modo per salvare e leggere le impostazioni del mio programma con un file .ini: ho trovato questo esempio nel sito della microsoft, solo che c'è un problema: non mi ritrovo nessun file .ini una volta lanciato il programma! E se provo a crearlo manualmente, me lo ritrovo comunque vuoto. Sapete consigliarmi qualcosa di meglio?

codice:
#include <windows.h> 
#include <tchar.h>
#include <stdio.h> 
 
int main() 
{ 
   TCHAR   inBuf[80]; 
   HKEY   hKey1, hKey2; 
   DWORD  dwDisposition; 
   LONG   lRetCode; 
   TCHAR   szData[] = TEXT("USR:App Name\\Section1");
 
   // Create the .ini file key. 
   lRetCode = RegCreateKeyEx ( HKEY_LOCAL_MACHINE, 
       TEXT("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\IniFileMapping\\appname.ini"), 
       0, 
       NULL, 
       REG_OPTION_NON_VOLATILE, 
       KEY_WRITE, 
       NULL, 
       &hKey1, 
       &dwDisposition); 
 
   if (lRetCode != ERROR_SUCCESS)
   { 
      printf ("Error in creating appname.ini key (%d).\n", lRetCode); 
      return (0) ; 
   } 
 
   // Set a section value 
   lRetCode = RegSetValueEx ( hKey1, 
                              TEXT("Section1"), 
                              0, 
                              REG_SZ, 
                              (BYTE *)szData, 
                              sizeof(szData)); 
 
   if (lRetCode != ERROR_SUCCESS) 
   { 
      printf ("Error in setting Section1 value\n"); 
      // Close the key
      lRetCode = RegCloseKey( hKey1 );
      if( lRetCode != ERROR_SUCCESS )
      {
         printf("Error in RegCloseKey (%d).\n", lRetCode);
         return (0) ; 
      }
   }

   lRetCode = RegCreateKeyEx ( HKEY_CURRENT_USER,

                               0,
