2 Dimension FileReadArray() Error 4053

[szczudlo6]

Hi All,

I have small issue with 2 dimenstion array. First I write array to .txt file and next i would like to read array to my array variables. Then occurs error 4053 "ERR_SOME_ARRAY_ERROR".

Could you help me? Please see below example script code for mql4:

#property copyright "FutureRobot"
#property version   "1.00"
#property strict

//+------------------------------------------------------------------+
//| Script program start function                                    |
//+------------------------------------------------------------------+
void OnStart()
{
  write();                                  
  read();
  
}

void write()
{
  int arr[2][2];
  
  arr[0][0]=123;
  arr[0][1]=213;
  arr[1][0]=2132;
  arr[1][1]=153;
  
  string FileName = "test2.txt";
  int fileOpenStatus = FileOpen(FileName,FILE_WRITE|FILE_BIN);
  FileWriteArray(fileOpenStatus,arr);
  FileClose(fileOpenStatus);
}  

void read()
{
   int arrs[][2];
   string FileName = "test2.txt";
   int fileOpenStatus = FileOpen(FileName,FILE_READ|FILE_BIN);
   uint w = FileReadArray(fileOpenStatus,arrs); // <------------------- ERROR 4053

   int gg = GetLastError(); //<-------get ERROR value 4053

   int a = (ArraySize(arrs)/2)-1;
   int b,c;
   
   for(int i=0;i<=a;i++)
   {
      b=arrs[i][0];
      c=arrs[i][1];
   }
  
   FileClose(fileOpenStatus);
}

I found the solution, see below:

#property copyright "FutureRobot"
#property link      "https://www.mql5.com"
#property version   "1.00"
#property strict

//+------------------------------------------------------------------+
//| Script program start function                                    |
//+------------------------------------------------------------------+
void OnStart()
{
  write();                                  
  read();
  
}

void write()
{
  int arr[2][2];
  
  arr[0][0]=123;
  arr[0][1]=213;
  arr[1][0]=2132;
  arr[1][1]=153;
  
  string FileName = "test2";
  FileDelete(FileName);
  int fileOpenStatus = FileOpen(FileName,FILE_WRITE|FILE_BIN);
  FileWriteArray(fileOpenStatus,arr);
  FileClose(fileOpenStatus);
}  

void read()
{
   int arrs[][2];
   string FileName = "test2";
   int fileOpenStatus = FileOpen(FileName,FILE_READ|FILE_BIN);
   uint w = FileReadArray(fileOpenStatus,arrs);
   int aa = (ArraySize(arrs)/2)-1;
   int r = ArrayResize(arrs,aa+1);
   uint ww = FileReadArray(fileOpenStatus,arrs);
   int gg = GetLastError();
   int a = (ArraySize(arrs)/2)-1;
   int b,c;
   
   for(int i=0;i<=a;i++)
   {
      b=arrs[i][0];
      c=arrs[i][1];
   }
  
   FileClose(fileOpenStatus);
}
