   //--- 
   if(list!=NULL) 
     { 
      printf("Object create error"); 
      return; 
     } 
   //--- open file 
   file_handle=FileOpen("MyFile.bin",FILE_READ|FILE_BIN|FILE_ANSI); 
   if(file_handle>=0) 
     { 
      if(!list.Load(file_handle)) 
        { 
         //--- file load error 
         printf("File load: Error %d!",GetLastError()); 
         delete list; 
         FileClose(file_handle); 
         //---
