0, In this lab, you will complete three different exercises, each dealing with a different aspect of interacting with the Windows API.
11, In the first exercise, you'll pass a string to Windows from your VB application, requesting that it be filled with the installed Windows directory.
21, And you'll display that information in a message box.
28, In the second exercise, you'll create a Topmost Window, that is, a window that will not move behind other windows, even when it looses the focus.
38, However, when it's in the non-topmost position then it will act as a normal window and move behind.
50, In the third exercise, you'll use a CallBack routine with a Windows timer.
54, Every time the CallBack routine is called, you'll update a progress bar.
