The Microsoft ZoomIn utility is a classic sdk tool in VC++6.0.

This is my first test to try to port a classic sdk tool.
Now, the ZoomIn utility is reimplemented using FASM.

This tool magnifies a portion of the screen,
allowing you to see things at a pixel level.

Press "Left" mouse key in the ZoomIn utility window
and hold on, then move your mouse to magnifies a portion of the screen.

Press "Arrow Up" key, "Arrow Down" key, "Arrow Right" key
and "Arrow Left" key to move a portion of the screen.

Other features:
You can incremet movement speed using "Ctrl" key.
Ex: "Ctrl" key + "Arrow Up" key

P.S. :
But, some more complicated functionality, such as copy to clipboard etc...
is still not reimplemented, this version is treated as alpha version.

Anyone can study and improve my source code.

I program fasm with 1.71 version.
Well, other old fasm version (like 1.69) should also assemble the source code.

The program works as it is expected but I think it would be better if the whole application window would work as a magnifier zooming in the area lying below and surrounding the geometrical center of the window. I mean that moving the main application window should cause immediate change of the view and give an illusion of the real lens moving over the desktop area.
