    Title="MainWindow" Height="350" Width="525">

    <Grid>

        <Image Height="150" HorizontalAlignment="Left" Margin="52,12,0,0" Name="Image1" Stretch="Fill" VerticalAlignment="Top" Width="200" />

        <Button Content="Openfile" Height="23" HorizontalAlignment="Left" Margin="52,198,0,0" Name="Button1" VerticalAlignment="Top" Width="167" />

        myDialog.ShowDialog()
