In Topic: Binding a list<string> to ListBox

Posted 16 Apr 2013

For your previous code to work, you should change how you are binding. First, you are binding to the property, but calling the .Add method on a list doesn't actually call the 'setter' of that property, which means it's not calling the NotifyPropertyChanged method. So you could change it to this...

<ListBox 
         x:Name="MyListBox"
         Grid.Column="0"
         Grid.Row="10"
         Grid.ColumnSpan="2" 
         Background="Transparent"
         ItemsSource="{Binding}"/>

public partial class MainWindow : Window, INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        protected void NotifyPropertyChanged(String info)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(info));
            }
        }

        ObservableCollection<string> _oListStars = new ObservableCollection<string>();

        private void Window_Loaded(object sender, EventArgs e)
        {
            _oListStars.Add("fruit");
            _oListStars.Add("chicken");
            _oListStars.Add("meat");
            MyListBox.ItemsSource = _oListStars;
        }

        private void Button_Click_2(object sender, RoutedEventArgs e)
        {
            _oListStars.Add("test");
        }
    }

The ObservableCollection implements the INotifyPropertyChanged interface, which will notify any control that it's bound to that it's items list has changed.

Post more code. Preferrably, post the code that around this code.
In Topic: Read Line XML File

Posted 11 Feb 2013

You could also use the XDocument class which is great for reading XML documents to use with LINQ-To-XML.

I agree with Martyr2 that you don't normally read an XML file the same way as a standard text file.
In Topic: question on automapping between entityobjects

Posted 8 Feb 2013

If you are wanting to map properties, why aren't your Business Objects inheriting from your Data Layer objects? If you want them to have essentially the same properties, make your Business Objects inherit from their Data Layer counterparts.
In Topic: How to free the unused occupied memory?

The long and sort of that means that your memory is going up because you are continuing to create objects that are remaining in scope (remaining alive).
```
Then when I don't need these objects anymore how to tell the garbage collector that they aren't being used anymore and are to be destroyed? I suspect not telling it might be the reason.

Using this code upon pressing the close button the current TabPage is closed and this is due to tab.Dispose(); - when I remove tab.Dispose(); the tabpage is not closed, so I thought tab.Dispose(); is also calling destructors and stuff, which delete all the objects belonging to the tab page, but apparently it isn't. How do I do that? I suppose that the tabpage is still kept in the memory even though it's not shown in the tabcontrol anymore.

Should I finalize the variables or set them to null or both or what?
You don't need to manually tell the GC to collect. You can, but it's frowned upon. The GC will collect when it gets ready to. There is no schedule. If you are removing all references and handling everything correctly in your Dispose, then the objects are getting disposed of correctly. However, the memory won't be reclaimed until the GC collects. That could be 2 minutes from the time you call Dispose, or 2 hours, or longer.

Don't worry about the size of the memory your application is using until you notice a problem like an OutOfMemoryException is thrown. Your app will consume a lot of memory. That memory will be reclaimed eventually if you are killing all of the references correctly.

As Adam states, one of the main "memory leaks" that occurs in .Net is when we do not unsubscribe from events. Anytime you manually do a "+=" to subscribe, you also need to unsubscribe("-="). Without the unsubscription, the object will remain in memory as it will still have a reference for the event handler.

Hey Ryan,
Just wanted to thank you for your post in this thread: http://www.dreamincode.net/forums/topic/161952-textwriter-help/
I'd been looking for a while about how to use the TextWriter with StreamWriter to append text.

I happen to agree with your personal message there, too many people take it personal.
