Question

I need to create a application which is similar to those we will get when we buy a laptop. It will be visible only when the mouse pointer reaches the top of the window. So how can I able to do this using C# 4.0 ?

I suppose there are several different ways to achieve this effect:

• You can place part of the window of your application above the visible screen, so only a part of it is visible (let’s say you can see only it’s bottom). Then you need to handle events when mouse enters (MouseEnter) and leaves (MouseLeave) the form to move the form up and down.
• You can use a background thread to call GetCursorPos method at a set interval (i.e. each 500ms) second to check where currently the mouse is. See this link for more information about it and a sample code: http://www.pinvoke.net/default.aspx/user32.getcursorpos.
  (If you need only to check the mouse position, you can use a timer to simplify you application.)
