I am trying to make lot reset button, but I need to get much better result then this, but I can't.
( I do not like all my ea's and indicators Button objects because all of them very ugly like this one. )

I need two things from you guys who can help and gives me good advice, please I really need your help.
I spent a lot of time, and I can't figure out what is a problem with my code.

Thanks in advance.

1. If it's hidden, how can you see and click on it?
2. ZORDER isn't boolean, it's an int 0...

Please you can just use the function from the documentation 'as is' to create the buttons just add it at the bottom of your code and you can call the function and pass the parameters.

So then you can just call:

ButtonCreate(...

Also

1. If it's hidden, how can you see and click on it?
2. ZORDER isn't boolean, it's an int 0...
   

Hidden is just hidden in the object list.

Thanks I fixed it, just it was a mistake.

Thanks Marco that will help me a lot, and my EA's codes looks like cleaned up.
Also I need to ask about below code, what is it, how is it work? (  even I read about that but I don not understand more clearly  )

Please explain it bit more, thanks in advance.

ObjectSetString ( 0, name, OBJPROP_TOOLTIP , tip );

----------------------------------------

Also I need to use void instead of bool like below code so which one is good?

bool ButtonCreate(...)

// or

void ButtonCreate(...)

[Marco vd Heijden]

The function either returns true or false depending in whether the button creation was successful or not so it depends on you if you want to verify that the button was indeed created.

For the second question the tooltip is what becomes visible when you hover your mouse over the object on the chart.

The way you are working now has limitations.

If you want to expand please read the following articles:

Huge thanks.
WOW, man you are going to be my man, Mr. Marco.

( since your first comment - you helped me a lot - you always try to understand my concerns - one more time huge thanks )

[Marco vd Heijden]

Well i just point you to these articles and we should be most thankful to the authors who wrote and also translated them.

I need to use .PNG file format in my EA's code, for LotSize icon.
But I found only .BMP file format, so can someone help me / advice me?

If any comment could quickly much appreciate, just I am hurry a bit more.
Thanks in advance.

[Max Enrik]

I try to if lotsize better then lotvalue 'State true' else 'State false'.
(  when I click 'Reset' object then turn to 'state false' and after I increase lot size state does not turn to true  ) 

Is below code wrong? 

//|     Lot Reset
if ( sparam == _namelotRset )
{
    if ( _lotSize > _lotValue )
    {
        ObjectSetInteger( 0, sparam, OBJPROP_STATE, true );
    }   //---if Close
    else
    {
        ObjectSetInteger( 0, sparam, OBJPROP_STATE, false );
    }   //---if Close
    _lotSize = _lotValue * _lotMin;

    _infoUpdate();
    return;
}   //---if Close

Thanks!

I try to make turn 'ON OFF' with below code.

ObjectSetString( chart_ID, name, OBJPROP_BMPFILE, on_off, file )

[Marco vd Heijden]

Please see:

https://www.mql5.com/en/docs/constants/objectconstants/enum_object/obj_bitmap

For the bitmap issue.

And for the other issue you can splice it into separate parts to set the state outside of sparam.
