Crash on MacOs
11 Jul 2024, 07:09

Hello Guys, I have a tool, which is working properly on Windows, But when I test it on MacOs. I got this message below? Can you help me about it?

I use combobox inside of it? may it cause the crash?

This problem happens because of the combobox, when I comment what is in the function, bot does not crash.

 

private void UpdateComboBox() 
       { 
          
           string[] itemsToRemove = { "ALL", "NO TRADE", "LONG TRADES", "SHORT TRADES" }; 
           foreach (var item in itemsToRemove) 
           { 
               posComboBox.RemoveItem(item); 
           } 

           foreach (var position in Positions) 
           { 
               if (position.SymbolName == Symbol.Name) 
               { 
                   string itemText = $"{position.Id}"; 
                   posComboBox.RemoveItem(itemText); 
               } 
           } 

           _buyCount = 0; 
           _sellCount = 0; 
           _posCount = 0; 

           foreach (var position in Positions) 
           { 
               if (position.SymbolName == Symbol.Name) 
               { 
                   string itemText = $"{position.Id}"; 
                   _posCount++; 
               } 
           } 

           if (_posCount == 0) 
           { 
               posComboBox.AddItem("NO TRADE"); 
               posComboBox.SelectedItem = "NO TRADE"; 
           } 
           else 
           { 
               posComboBox.AddItem("ALL"); 
               posComboBox.SelectedItem = "ALL"; 
           } 

           foreach (var position in Positions) 
           { 
               if (position.SymbolName == Symbol.Name) 
               { 
                   if (position.TradeType == TradeType.Buy) _buyCount++; else _sellCount++; 

                   string itemText = $"{position.Id}"; 
                   posComboBox.AddItem(itemText); 
               } 
           } 

           if (_buyCount > 0) 
           { 
               posComboBox.AddItem("LONG TRADES"); 
           } 

           if (_sellCount > 0) 
           { 
               posComboBox.AddItem("SHORT TRADES"); 
           } 
       }

Hi there,

Please share the complete code so that we can just copy/paste, build and run it, and see the problem.

RE: RE: Crash on MacOs

After MacOs 5.0.1 Update, crashing issue is solved.

But I am facing some other problems right now.

As you can see from 2 videos below, same code, on same pair but getting different outcomes when I print results of combobox.SelectedIndex and combobox.SelectedItem

Windows 
MacOs
