reloaded wpf window

I have main wpf window, in this window I create new slave windows and add in dictionary. It is possible, after closing the slave window, it showed once again.

public class MainWindow:Window
{
private dictionary<string, SlaveWindow> _winDic= new dictionary<string, SlaveWindow>();

public void SomeMethod()
{

var mySlaveWindow = new SlaveWindow();
//add to dictionary
_winDic.Add("mySlaveWindow",w);

//close slave window w


//show
_winDic[mySlaveWindow].Show();
}
}

This following way of doing this is taken from this msdn page.

Subscribe to the Closing event for the Window and add this in code behind.

private bool m_close = false;
// Shadow Window.Close to make sure we bypass the Hide call in 
// the Closing event handler
public new void Close()
{
    m_close = true;
    base.Close();
}
private void Window_Closing(object sender, CancelEventArgs e)
{
    // If Close() was called, close the window (instead of hiding it)
    if (m_close == true)
    {
        return;
    }
    // Hide the window (instead of closing it)
    e.Cancel = true;
    this.Hide();
}

This will make sure your Window finally closes and is not left hanging.

You'll need to hide the window rather than closing it.

If you call Hide(), the window will vanish like it would when you call Close() but you'll be able to reshow it later by calling Show() again.
