App won't come to the foreground when started

Question

This is a MSDN question asked by Will Pittenger, the source is App won't come to the foreground when started.

I have a WPF application that when I start it from Visual Studio, its main Window goes to the background rather than becoming the foremost window. I tried adding the code below to the Window, but had no effect.

protected override void OnInitialized(System.EventArgs e)
{
base.OnInitialized(e);
Activate();
}

What am I doing wrong?

Hi,

Welcome to our Microsoft Q&A platform!

You can try the following code:

 public partial class MainWindow : Window
    {
        [DllImport("user32.dll")]
        private static extern int SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, int uFlags);
        static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);
        const int SWP_SHOWWINDOW = 0x0040;
        public MainWindow()
        {
            InitializeComponent();
            IntPtr handle = new WindowInteropHelper(this).Handle;
            SetWindowPos(handle, HWND_TOPMOST, 0, 0, 100, 200, SWP_SHOWWINDOW);
        }   
    }

Thanks.
