why return this worning loss data conversion ?

Hi  when i run a library of Bernd Kreuss base64 

//+------------------------------------------------------------------+
//| Encoding data in base64                                          |

void _Base64Encode(string in,string &out)
  {
   int i=0,pad=0,len=StringLen(in);
//---- Let's go through and encode
   while(i<len)
     {
      //---- Extracting bytes
      int b3,b2,b1=StringGetChar(in,i);
      i++;
      if(i>=len) { b2=0; b3=0; pad=2; }
      else
        {
         b2=StringGetChar(in,i);
         i++;

           break;
         case 2:
           out=out+"==";
           break;
        }
     }

return me the  error   here  out=out+CharToStr(_ExtBase64Encode[c3]);

Who is " Bernd Kreuss " ? Are we supposed to know him and know what you are talking about ?

i suppose is  this

Jup. It's an int. CharToStr has uchar as input.

Change the call to this:

CharToStr((uchar)_ExtBase64Encode[c3]);
EDIT:

Or change this

static int
to this:

static uchar
EDIT: fixed a typo
 

i change  declaration integer  to uchar  , but now  retorn me  only  this  error 


//+------------------------------------------------------------------+
//| Decodin data in Base64                                           |
//+------------------------------------------------------------------+
void _Base64Decode(string in,string &out)
  {
   int i=0,len=StringLen(in);
   int shift=0,accum=0;
//---- Going to the end
   while(i<len)
     {
      //---- Extracting the code
      int value=_ExtBase64Decode[StringGetChar(in,i)];
      if(value<0 || value>63) break; // End or incorrect encoding
      //---- Reversing the code
      accum<<=6;
      shift+=6;
      accum|=value;
      if(shift>=8)
        {
         shift-=8;
         value=accum >> shift;
         out=out+CharToStr(value & 0xFF);
        //out = out + IntegerToString(value & 0xFF);
        } 
      i++;
     }
//----
  }
//+------------------------------------------------------------------+

in 

 out=out+CharToStr(value & 0xFF);

possible loss of data due to type conversion    common_functions.mqh    2077    34

i try to modify 

CharToStr((ucahr)value & 0xFF]);

but tell me uchar  not  exist like variable

This is an int.

value & 0xFF
You need to cast it again...


(uchar)(value & 0xFF)

Second: seemse a typo on your side.

EDIT;

You copied my typo...
 
myth now  work  thanks  so very much
