to a new file i got new lines where thr were specials characters and
some times nothing ....

AOA!

        send the code how you are doing ? try this function

 

#define  COPY_OK   1

#define COPY_ERROR -1

 

int FileCopy
  ( const char *src,
    const char *dst )
{
#define BUFSZ 16000

char            *buf;
FILE            *fi;
FILE            *fo;
unsigned        amount;
unsigned        written;
int             result;

buf = new char[ BUFSZ];

fi = fopen( src, "rb" ) ;
fo = fopen( dst, "wb" );

result = COPY_OK;
if  ((fi == NULL) || (fo == NULL) )
  {
  result = COPY_ERROR;
  if (fi != NULL) fclose(fi);
  if (fo != NULL) fclose(fo );
  }

if (result == COPY_OK)
  {
  do
    {
    amount = fread( buf, sizeof(char), BUFSZ, fi );
    if (amount)
      {
      written = fwrite( buf, sizeof(char), amount, fo );
      if (written != amount)
        {
        result = COPY_ERROR; // out of disk space or some other disk err?
        }
      }
    } // when amount read is < BUFSZ, copy is done
  while ((result == COPY_OK ) && (amount == BUFSZ));
  fclose (fi);
  fclose(fo);
  }
delete [] buf;
return(result);
}

 

Hope it will work ,

This will be done in the same way make a copy of Edit buffer and pass it to file write func

 

written = fwrite( buf, sizeof(char ), amount, fo );
 

buf contain the edit data  as simple as that !

 

    amount = fread ( buf, sizeof(char), BUFSZ, fi );
    if (amount)
      {
      written = fwrite ( buf, sizeof(char), amount, fo );

      if (written != amount)
        {
        result = COPY_ERROR; // out of disk space or some other disk err?
        }
      }
    } // when amount read is < BUFSZ, copy is done
  while ((result == COPY_OK ) && (amount == BUFSZ));
  fclose (fi);
  fclose(fo);
  }
delete [] buf;
return(result );
}

 

Hope it will work ,
