Help with Custom MQL4 code

[Abade69]

I want to use the following code inside an EA:

//+------------------------------------------------------------------+

#property copyright "Copyright © 2010, zznbrm"
#property show_inputs

#import "user32.dll"
   int      PostMessageA(int hWnd,int Msg,int wParam,int lParam);
   int      GetWindow(int hWnd,int uCmd);
   int      GetParent(int hWnd);
#import

#define GW_HWNDFIRST 0
#define GW_HWNDNEXT  2
#define WM_COMMAND   0x0111

extern int eintTF = PERIOD_W1;
                   
int start()
{      
   bool blnContinue = true;   
   int intParent = GetParent( WindowHandle( Symbol(), Period() ) );   
   int intChild = GetWindow( intParent, GW_HWNDFIRST );  
   int intCmd; 
   
   switch( eintTF )
   {
      case PERIOD_M1:   intCmd = 33137;  break;
      case PERIOD_M5:   intCmd = 33138;  break;
      case PERIOD_M15:  intCmd = 33139;  break;
      case PERIOD_M30:  intCmd = 33140;  break;
      case PERIOD_H1:   intCmd = 35400;  break;
      case PERIOD_H4:   intCmd = 33136;  break;
      case PERIOD_D1:   intCmd = 33134;  break;
      case PERIOD_W1:   intCmd = 33141;  break;
      case PERIOD_MN1:  intCmd = 33334;  break;
   }
   
   if ( intChild > 0 )   
   {
      if ( intChild != intParent )   PostMessageA( intChild, WM_COMMAND, intCmd, 0 );
   }
   else      blnContinue = false;   
   
   while( blnContinue )
   {
      intChild = GetWindow( intChild, GW_HWNDNEXT );   
   
      if ( intChild > 0 )   
      { 
         if ( intChild != intParent )   PostMessageA( intChild, WM_COMMAND, intCmd, 0 );
      }
      else   blnContinue = false;   
   }
   
   // Now do the current window
   PostMessageA( intParent, WM_COMMAND, intCmd, 0 );
}

But then i get this:

What should i change to make it work?

There is no particular field where you can set such information to be embedded to the output EA (but I should add some). Only if you make a custom block you can put such information under "Global variables, includes" and then when the block is used, the information is automatically embedded.

that would be perfect

Is there any other way to loop that code with FxDreema? (or any way to change time frames with the existent blocks). I really don't wanna use autokey macros. Also, the block builder has bugs: Everytime i try to click something it minimizes itself, it saved my first block and can use it, but not the second one (for some reason).

I'm aware about this problem in the desktop version, but I stopped making desktop versions year ago. Since then I rewrote everything from PHP to NodeJS and I will update everything on the server probably after few days. In other words, PHP is history, as well as the current desktop version. I of course tried to find why this problem appears back then, without success. I used ExeOutput for PHP to make it, and this software is not only buggy, but also unsupported.
