Window launch effects, using the Win32 API

A window effect code that uses the API. You can try it, is not in the window display will show a variety of special effects. It's a little bit of a surprise.

[System.Runtime.InteropServices. DllImport("user32")]
private static extern bool animatewindow (IntPtr hwnd, INT Dwtime, int dwflags);
Private const int aw_hor_positive = 0x0001; // display from left to right
Private const int aw_hor_negative = 0x0002; // display from right to left
Private const int aw_ver_positive = 0x0004; // display from top to bottom
Private const int aw_ver_negative = 0x0008; // display from bottom to top
Private const int aw_center = 0x0010; // from the middle to the perimeter
