Hi friends

I use this function on old dos days to determine is an key was pressed
#define TECLA_SHIFT_D     0
#define TECLA_SHIFT_E     1
#define TECLA_CTRL        2
#define TECLA_ALT         3
#define TECLA_SCROLL_LOCK 4
#define TECLA_NUM_LOCK    5
#define TECLA_CAPS_LOCK   6
#define TECLA_INSERT      7
#define SEGMENTO_OFFSET   0x00400017

bool kbstatus( int nKey){

   int nStatus;

   nStatus = ( int ) ( ( *( char * ) SEGMENTO_OFFSET ) );

   return (KeyStatus(nStatus,nKey);

}


int KeyStatus( int nStatus, int nKey )
{
   int lStatus;
   int hKey;

   switch(nKey){
      case TECLA_SHIFT_D:
         hKey = 0x1;
         break;
      case TECLA_SHIFT_E:
         hKey = 0x2;
         break;
      case TECLA_CTRL:
         hKey = 0x4;
         break;
      case TECLA_ALT:
         hKey = 0x8;
         break;
      case TECLA_SCROLL_LOCK:
         hKey = 0x10;
         break;
      case TECLA_NUM_LOCK:
         hKey = 0x20;
         break;
      case TECLA_CAPS_LOCK:
         hKey = 0x40;
         break;
      case TECLA_INSERT:
         hKey = 0x80;
   }

   return(nStatus & hKey);

}

Use the GetKeyState() or GetAsyncKeyState() function from the Win32 API
instead.
