CHART_AUTOSCROLL according the mouse wheel - page 2

[Thierry Ramaniraka]

Thank you very much .

kypa:

The wheel click is assigned for haircross so you may run into conflict (sometimes your functions execute, sometimes a crosshair appears).

I want both of these functions, the orginal cross hair, and my custom fonction.

kypa:

If you want to use the scroll wheel it's the same procedure with id==CHART_EVENT_MOUSE_WHEEL and lparam. Except you need Build 1121, because Build 1090 doesn't support it. 

How can I force update it please ?

[kypa]

Just register a demo account at MetaQuotes-Demo server from terminal (File/Open account) and it will update.

Unless you're running XP or Vista, then it won't update.

Kypa is right . Try this as well (althought it may be firing due to MouseWheel event ) 

bool CrosshairMode=false;
int OnInit()
  {
  CrosshairMode=false;
  ClickAndScroll=false;
  ChartSetInteger(0,CHART_EVENT_MOUSE_MOVE,true);
  ChartSetInteger(0,CHART_KEYBOARD_CONTROL,true);

IT doesn't work. :-/
Does not allow me to go on.

And tried to real account from meta quotes server too...
But still the same old version... :-/

[kypa]

There are no real accounts from MetaQuotes.

Write longer name and bogus e-mail. And random numbers for phone, not just zeros.

What OS do you have?
