VS2010

I am working on a vs2010 WPF project
and I'm currently working on login
login is ok but after that the supposedly MainWindow is Blank(but i designed it in Designer)

C#

Project.MainWindow main = new Project.MainWindow();
                    App.Current.MainWindow = main;
                    this.Hide();
                    main.Show();
                    this.Close();

MainWindow that i Called Show only Blank(WhiteScreen)with Border

XML

Height="550" Width="1000" AllowsTransparency="True" ResizeMode="NoResize" Topmost="True" WindowStyle="None">

but i set it without border.

as I searched google for answer
to switch Wpf window

C#

MainWindow main = new MainWindow();
    App.Current.MainWindow = main;
    this.Close();
    main.Show();

i don't know but why my MainWindow is Blank?

"why my MainWindow is Blank?", could be any number of reasons. Nothing you have presented here would lead anyone to believe that your MainWindow would actually contain anything at all.

What is "this" in this fragment? Why those manipulations? Where Application.Run is called? You just don't show appropriate context of your problem, which looks quite easy.

I'm quite Speechless
Jokler.007 is right
To Load the Data/Design of the Window,
one should never forget to Inialize it's Component. because if not, it will be Blank.

MainWindow.xaml.cs

C#

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent(); 
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {

        }

    }
}

Sorry I'm just new to C#

Solution 1

hello try this :

Project.MainWindow main = new Project.MainWindow();
main.Owner = this;
this.Hide();
main.Show();

in the second form in the constructor don't remove this :

InitializeComponent();

and the second form on the event close add this to show the main form again mean the login one :

this.Owner.Show();

Not quite clear. It depends in what context this code is... The same goes about the OP's code.
