Hello freinds,

 

I have an indicator in MQL4, with the following code line:

 PostMessageA(hwnd,WM_COMMAND,33324,0); 

 The 2 colored builtin indicator are not known at MQL5.

 

Can somebody explain how to imigrate these 2?

 

Thanks. 

They are also undefined in MQL4. Maybe PostMessageA is a custom function and WM_COMMAND is a custom define?

Thank you enivid, but this is what is written in MQ4 indicator:

 

         //---- refresh window not frequently than 1 time in 2 seconds
         if(hwnd!=0 && cur_time-last_time>=2)
           {
            PostMessageA(hwnd,WM_COMMAND,33324,0);
            last_time=cur_time;

           }

Can somebody help...?

Yeah, that can be written in MQ4 indicator but for it to work even in MT4 hwnd, WM_COMMAND and PostMessageA() should be defined somewhere in this indicator or in the included file.
