Hide one desktop window or disable closing button - Windows Desktop App

Question

I am creating a Windows Desktop App to run on Windows 8.1 Pro.

Programmatically I can minimize it using this property:

WindowState.Minimized;

Is there a way to hide it completely instead, or disable the user to close it?

I tried with all these StackOverflow solutions but

they dont work to me.

I tried with

private const int GWL_STYLE = -16;
private const int WS_SYSMENU = 0x80000;
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

and

var hwnd = new WindowInteropHelper(this).Handle;
SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_SYSMENU);

then I tried with adding the below method to my windows class

protected override void OnClosing(CancelEventArgs e)
{
   base.OnClosing(e);
   e.Cancel = true;
}

the I tried with this property

        WindowStyle = WindowStyle.None;

still with no luck.

How can I get it?

I am using VS2015 and WPF

Can't be, i do it few times, always work fine. M.b. you have some another logic to window that disable it at runtime. https://msdn.microsoft.com/en-us/library/system.windows.window.windowstyle(v=vs.110).aspx — MrDywar, Sep 10 '15 at 15:32

Simply set the ShowInTaskBar property to False in your xaml-

ShowInTaskbar="False"

and in the c# code, just hide your window on the program initialization:

  public MainWindow()
    {
        InitializeComponent();
        this.Hide();
    }

Goodluck.
