MT5 toggle AutoTrading button

 
Hello. Can Anybody help me? I found the following code that works on MT4 to toggle AutoTrading button:

#include <WinUser32.mqh>
#import "user32.dll"
int GetAncestor(int,int);
#define MT4_WMCMD_EXPERTS  33020
#import

void OnTick()
  {
   int main=GetAncestor(WindowHandle(Symbol(),Period()),2/GA_ROOT/);
   PostMessageA(main,WM_COMMAND,MT4_WMCMD_EXPERTS,0);    // // Toggle Expert Advisor button 
  }


I tried to convert to MQL5, but it didn't work:

#include <WinAPI\winuser.mqh>
#define WM_COMMAND   0x0111
#define MT5_WMCMD_EXPERTS  32851
#import


ENUM_TIMEFRAMES TFMigrate(int tf)
  {
   switch(tf)
     {
      case 0: return(PERIOD_CURRENT);
      case 1: return(PERIOD_M1);
      case 5: return(PERIOD_M5);
      case 15: return(PERIOD_M15);
      case 30: return(PERIOD_M30);
      case 60: return(PERIOD_H1);
      case 240: return(PERIOD_H4);
      case 1440: return(PERIOD_D1);
      case 10080: return(PERIOD_W1);
      case 43200: return(PERIOD_MN1);
      
      case 2: return(PERIOD_M2);
      case 3: return(PERIOD_M3);
      case 4: return(PERIOD_M4);      
      case 6: return(PERIOD_M6);
      case 10: return(PERIOD_M10);
      case 12: return(PERIOD_M12);
      case 16385: return(PERIOD_H1);
      case 16386: return(PERIOD_H2);
      case 16387: return(PERIOD_H3);
      case 16388: return(PERIOD_H4);
      case 16390: return(PERIOD_H6);
      case 16392: return(PERIOD_H8);
      case 16396: return(PERIOD_H12);
      case 16408: return(PERIOD_D1);
      case 32769: return(PERIOD_W1);
      case 49153: return(PERIOD_MN1);      
      default: return(PERIOD_CURRENT);
     }
  }

void OnTick()
  {
      int main=GetAncestor(WindowHandle(Symbol(),Period()),2/*GA_ROOT*/);
      PostMessageW(main, WM_COMMAND,MT5_WMCMD_EXPERTS,0);    // // Toggle Expert Advisor button 
  }

int WindowHandle(string symbol,int tf)
  {
   ENUM_TIMEFRAMES timeframe=TFMigrate(tf);
   long currChart,prevChart=ChartFirst();
   int i=0,limit=100;
   while(i<limit)
     {
      currChart=ChartNext(prevChart);
      if(currChart<0) break;
      if(ChartSymbol(currChart)==symbol
         && ChartPeriod(currChart)==timeframe)
         return((int)currChart);
      prevChart=currChart;
      i++;
     }
   return(0);
  }  

Any suggestions or ideas?

 

A simpler attempt (that didn't work either) based on a suggestion of Alain Verleyen was: 


#include <WinAPI\winuser.mqh>

#define WM_COMMAND 0x0111
#define MT5_WMCMD_EXPERTS 32851

void OnStart()
  {
   int wHandle=(int)ChartGetInteger(0,CHART_WINDOW_HANDLE);
   long hMDI=GetParent(GetParent(wHandle));
   Print(hMDI);
   PostMessageW(hMDI,WM_COMMAND,MT5_WMCMD_EXPERTS,0);
  }

Fantastic! it's a completely different aproach (it doesn't use postmessage), but most important: it's works! Thanks Alain!
