Sysmets2
--------

This is another Win32 assembly demo, which is based on the the "C" example in 
Charles Petzold's "Programming Windows" 5th edition.

It demonstrates the use on the scroll bar for moving data so that hidden data becomes more
visible within the application window. This example only has a vertical scroll bar.

To test it run the program and then use the mouse to test the following.

1. Click the lower mouse arrow and the displayed data will move up one line.
2. Click the upper mouse arrow and the displayed data will move down 1 line.      
3. Click the scroll bar between the "Thumb" and the bottom and data will move up 1 page.
4. Click the scroll bar between the "Thumb" and the top and the data will move down 1 page.
5. Drag the "Thumb" with the mouse to move the data up or down.
  
Files included are:-

Sysmets2.exe	The demo
Sysmets2.asm	The source
Sysmets.inc	The System metrics data
Makefile	

The size of the program is 9K compared to 28k for the "C" version !

Appart for being a demo, this program reveals useful data about the various graphical items
in Windows, such as the display size in pixels etc. Have fun.
