How do you disable Aero Snap in an application?

Question

Is it possible to disable the automatic window-docking feature of Windows 7 in a WPF application?

Answer 1

A rather simple solution I found that works with borderless windows as well: Just hide the maximize button (event if it's already not displayed due to the lack of caption bar):

    [DllImport("user32.dll")]
    private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
    [DllImport("user32.dll")]
    private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
    private const int GWL_STYLE = -16;
    private const int WS_MAXIMIZEBOX = 0x10000;

    private void Window_OnSourceInitialized(object sender, EventArgs e)
    {
            var hwnd = new WindowInteropHelper((Window)sender).Handle;
            var value = GetWindowLong(hwnd, GWL_STYLE);
            SetWindowLong(hwnd, GWL_STYLE, (int)(value & ~WS_MAXIMIZEBOX));
    }
