A very handy application that's included with the Windows operating system is the magnifier, which you can find in the accessibility folder. Basically, the windows magnifier is designed for computer users who suffer from any form of vision impairment. It acts as a magnifying lens that enlarges a section of the screen when the mouse moves over it. I often use the windows magnifier myself, but I have found a few areas of the program that need a little improvement, that's why I decided to write my own magnifier.

In this article I will show you how easy it is to write your very own magnifier using Visual Basic 6. We will be making use of several Windows API calls however, so you should read my article about Windows API calls first.
