CEdits lose their value

[Juan Luis De Frutos Blanco]

Good afternoon,

I have a problem with a panel created with CAppDialog.

The CEdits that I manually feed lose their value when I change the TimeFrame.

Is there any way to avoid it?

Thnaks in advance,

Juan

when you change timeframe your indicator/ea is restarted so you need to anticipate this and save any variables that you want to keep first and reset them when it restarts.

you can use terminal global variables or write data to a file to achieve this

Here is the modification of the panel. What has been done: the 'edit_value' variable is declared in the EA (NOT IN THE PANEL!!!).

//+------------------------------------------------------------------+
//| Global Variables                                                 |
//+------------------------------------------------------------------+
CControlsDialog ExtDialog;
string edit_value="-1"; // '-1' -> start value
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()

When deinitializing to this rename, we save the value from the CEdit element. Two methods have been added to the panel:

   //--- create
   virtual bool      Create(const long chart,const string name,const int subwin,const int x1,const int y1,const int x2,const int y2);
   //--- chart event handler
   virtual string    GetValue(void)            const  { return(m_edit.Text());   }
   //--- chart event handler
   virtual void      SetValue(const string value)     { m_edit.Text(value);      }

protected:
   //--- create dependent controls
   bool              CreateEdit(void);

Added print statements to OnInit and OnDeinit so you can control the 'edit_value' variable

Very thankful. It works perfectly.

Best regards,
