Requirment

To animate a windows form while displaying it to user , just like a powerpoint slides effects.

Solution

To get such powerpoint slides effect can be achieved using Win32 API . the only problem here is that its unmanged code.

Note : sample code below is in C#

1) Add a reference to you class file
using System.Runtime.InteropServices;

2) import user32 dll with following syntax
[DllImport("User32.dll")]
static extern bool AnimateWindow(System.IntPtr handle, int time, int value);
3) call AnimateWindow function at windows form load event


Arguments
1) Handler(this. handle) of form(to be animated)
2) time(in milliseconds) to specify how much time animation will take (faster or slower)
3) values(in hexadecimal ) which specify how the form will be displayed (left to right, right to left, top to bottom, bottom to top or center etc..)

The last values are or'd together and can be any of the following:
