Hello every one, I'm making a EA that uses a ComboBox and I can't get the value, for instance: this instruction "Comment(m_field.Value());" should print the value of the current CombBbox field like a string and so on, but instead, it shows me the index of the array(in this case the ComboBox list). I don't know if it's a common error in the class ListView.mqh or Edit.mqh. I would like to know what´s wrong or if I must re-install MT5.
Thank you so much in advance.

This is the snippet to create the control...
bool CTrade::CreatePipsST(void) { //--- coordinates int x2=(ClientAreaWidth()- CONTROLS_GAP_X*3) - EDIT_WIDTH*2; int x1= x2 - (EDIT_WIDTH + 20); int y1=INDENT_TOP+(EDIT_HEIGHT+CONTROLS_GAP_Y)+ 5*CONTROLS_GAP_Y; int y2=y1+EDIT_HEIGHT; //--- create if(!m_field_pips_st.Create(m_chart_id,m_name + "ComboBoxPipsST",m_subwin,x1,y1,x2,y2)) return(false); if(!m_field_pips_st.ReadOnly(false)) return(false); if(!Add(m_field_pips_st)) return(false); //--- fill out with strings for(int i=0;i<110;i+=10) if(!m_field_pips_st.ItemAdd(IntegerToString(i))) return(false); //--- succeed return(true); }
... and this is the event to get the value and show it into the chart.
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CTrade::OnChangeFieldPipsST(void) { Comment((m_field_pips_st.Value()); }
This is the result
For instance I select the value "30" and print the position 3. What´s wrong? It should print the value "30". I think that the problem is some class by default like the Edit.mqh, ComboBox.mqh or ListView.mqh class I'm not sure. I would like that you do the same control and prove it in your PC and tell me if this control works well in your PC.
Thank you very much .
